Frequently Asked Questions

While we are always available one-on-one to answer any questions and/or discuss how JNIOR can help your company, we wanted to answer some of the more frequently asked questions.

Contact INTEG Process Group for additional assistance with your Technical Questions and General Questions.

General Questions

Where is the JNIOR manufactured?

The JNIORs and Expansion Modules are made in the USA. We purchase the PCBs from a company a company in the US. The components are sourced globally. The PCB and components go through surface mount assembly here in the office. Programming and testing is also performed in our office.

What does “JNIOR” stand for?

JNIOR (pronounced “junior”) is a Network I/O Resource utilizing the Java™ platform.

What are the JNIOR Certifications?

TUV Safety Mark (IEC, EN 60950), CE Mark, FCC Class B, CB Scheme Available, RoHS Compliant. A copy of the TUV Certification PDF can be obtained from the All Downloads page.

How much does the JNIOR weigh?

11 ounces (312 grams).

What is the warranty on JNIOR?

2 years. Here is the JNIOR Warranty

How do I submit an RMA?

If you want to return your JNIOR via an RMA, make sure you contact INTEG support first. They will try and review your JNIOR and if it is defective will help you with the RMA process. They can be contacted at support@integpg.com or through our chat on our website.

How does the JNIOR internal time clock keep current?

The JNIOR has NTP (Network Time Protocol) capability.  You can enter an IP address (or URL) and the JNIOR will sync its time when it boots up with that computer. It will continue to sync it every 4 hours.

Do JNIOR Expansion Modules need power?

No. The modules draw their power via the Sensor Port on the JNIOR.

How many Expansion Modules can be connected to one JNIOR?

Multiple plug-and-play expansion modules can be daisy-chained to the JNIOR via the Sensor Port.  The exact number of modules that can be connected is a function of the mix of expansion modules being used.  Each module draws differing amounts of current. Please contact INTEG with your proposed mix of expansion modules.

What programming language do I use to program the JNIOR?

The applications on the JNIOR are developed using Java, but we have standard applications included with each JNIOR that meet a variety of needs so 99% of our customers do not actually do any programming on the JNIOR! But if you want to add your own software, we would be glad to help you get started.

What is the recommended power for the JNIOR?

We recommend 12 Volts DC at 1 Amp.  Although the JNIOR can handle 12 – 24 VDC or AC for the JNIOR power supply. The JNIOR digital inputs and relay outputs handle 0 – 60 volts DC or AC. 

Support Questions

How do you take a Snapshot?

To take a snapshot, you open the support tool and go to the snapshot tab. There you’ll click “take snapshot” and select the JNIOR you want to take a snapshot of.

How do you control external modules with a macro?

To control an external module with a macro command, you’ll create a macro in the support tool and send it to the analog presets program using cinema.

How do you close or pulse an output when the JNIOR boots?

In order to close an output on boot, you can open the support tool and go to the configuration page. On the configuration page in the outputs section, you can set the initial action of any channel to 0 which will close that output on boot. If any positive number is set in the initial action, that output will pulse for that many milliseconds on boot.

How do you invert an input?

Inputs can be digitally inverted on JNIORs to help test when they are triggered. Inverting an input can be done via the JNIOR Web Page, or by setting the ‘Inversion’ registry key through the command line.

How do you view the Environmental Monitoring Module data?

To view data from an environmental monitoring module in a graph, you use the Grapher and Tasker applications. You configure Grapher to read data from logs that will be created by Tasker. You then configure Tasker to log the data from the environmental monitoring module.

Can the JNIOR use the MQTT protocol?

The JNIOR can use the MQTT protocol. You can use the MQTT application to send information through the JNIOR message pump. You configure the MQTT application to a public broker and then send messages from another application on the message pump.

Why can’t the JNIOR connect to a MODBUS server?

The JNIOR can connect to a MODBUS server, but you need the MODBUS application. This application is separate from the Operating System and needs to be activated or else you can’t connect to a MODBUS server. You can do this by going to the application section of the configuration tab in the JNIOR’s WebUI, and clicking the checkbox next to the MODBUS server application.

How do I reboot my JNIOR?

One way you can reboot a JNIOR is simply by pulling the power and plugging it back in. You can also go to the command line from the support tool or JNIOR web page and type “reboot” and then type “y”. This will initiate a reboot as well.

How do I reset my JNIOR back to its factory default?

WARNING: Doing this wipes all data on your JNIOR, be sure this is what you want to do before executing a factory reset. To do a factory reset, its similar to a normal reboot from the command line, but the full command is “reboot -eraseall” followed by “y”. This will NOT work for the Series 3 JNIOR. There is a post explaining how to factory reset a Series 3 JNIOR.

How do I transition from a Series 3 to a Series 4 JNIOR?

Series 4 JNIORS were made to be a drop in replacement for Series 3 JNIORs. While some applications are only usable on Series 3 JNIORs, typically Series 4 JNIORs have an application that provides the same functionality and can be switched to. While different setups may require different steps to upgrade, you can always reach out to JNIOR support for help performing said upgrade.

How do I look at the connections on my JNIOR?

In the command line of the JNIOR, if you type “netstat” a list of connections on the JNIOR will be displayed. A post about the netstat command is in the knowledge base.

How do I use the JNIOR’s WebUI?

The JNIOR’s WebUI (Previously called the DCP) allows you to access and control tons of setting on your JNIOR. It can be accessed by right clicking your JNIOR in the support tool and opening its web page or by typing its IP into a web browser’s URL.

How do I update a JNIOR with an application?

To put an application on the JNIOR, you’ll need to download the application from our website, then open it (Don’t Unzip) in the update tab of the Support Tool. You’ll select ‘publish’ and the JNIOR to update the application to, and once it completes your JNIOR should have that application on it. There is an example post on updating Cinema to a JNIOR as well.

How do I access a JNIOR application that has a webpage?

There are two ways to usually access an application on a JNIOR. One way is by opening the JNIOR’s WebUI and under the configuration tab, in the application section, clicking its pop-out link. If the application doesn’t have a pop-out link, it you can also be accessed by opening a web browser, and typing in the URL your JNIOR’s IP Address followed by /”application name”.

How do I set the time on my JNIOR?

To set the JNIOR’s date and time, you’ll want to access either command line from the support tool or JNIOR web page and login in. You can then enter “date” followed by the date and time you want on the JNIOR formatted as “MMDDYYYYHHMMSS”.

How do I take a backup of my JNIOR?

To take a backup of the JNIOR, you’ll need the support tool. In the Snapshot tab of the support tool, you can select the Take Backup button which can will copy the configurations and files from a JNIOR and create a backup of it that can be transferred to other JNIORs to clone the configuration or to revert to an older configuration if a mistake is made.

Why won’t my JNIOR’s web page load, or show in the support tool?

When the JNIOR is loaded on the network they have DHCP enabled, which checks the network the JNIOR is on and assigns it an IP available. If your network doesn’t support DHCP then your JNIOR will default to the address 10.0.0.201. If another device on the network has 10.0.0.201, then the JNIOR will forgo the IP address and set itself to 0.0.0.0 to avoid an IP conflict. Even if no other unit has the same IP as your JNIOR, this issue can also be caused from your JNIOR’s IP address not being compatible with your computers IP address. To fix this, you need to change the IP address of the JNIOR, which a post explains here.

Whats the difference between Tasker and Task Manager?

Tasker is a new application that was made to replace the Task Manager application. Task Manager was made for Series 3 JNIORs, and aren’t able to use Tasker. Tasker on the other hand was made for Series 4 JNIORs, which has improved functionality and is easier to configure. For more information, click here.

I have a system that declares the JNIOR as a device and connects on port 9200. Why is it not connecting?

When this happens its typically when a connection is initially being made to the JNIOR during setup. Give your system connecting to the JNIOR a reboot and the connection should establish itself. You can check which ports the JNIOR is listening on using the netstat command.

I’m sending a command to the JNIOR via a TCP/Serial connection, but why isn’t the JNIOR doing anything?

Something that commands need to include when being sent to the JNIOR is the termination string. For example, if your connecting to the JNIOR using Cinema the default termination string is \r\n. So when you send the JNIOR a command in Cinema, make sure the command ends with \r\n. To check what termination string you need for your connection, based off the application your using on the JNIOR, you can check in the application registry keys in the JNIOR registry of a JNIOR’s web page. (appdata/application name). If its a TCP connection, you may want to also check and make sure the JNIOR is listening on the port you are sending to. You can check which ports the JNIOR is listening on using the netstat command.

CINEMA.JAR is an advanced digital cinema automation program that runs on the JNIOR to provide central control functionality for a theatre implementing a digital cinema system. The Cinema program can also be used for other audio-visual applications because of its ability to control both I/O on the JNIOR and to send commands to devices on the network.

Controls Other Devices
Cinema.Jar software enables the JNIOR to interface with a variety of systems and devices by running ‘macros’ on the JNIOR. Devices that can be controlled include practically any device. INTEG has built-in some standard commands for some widely used devices, but by adding a RAW Ethernet or RAW Serial device, the user can add any command needed to the JNIOR macros. A sample of devices include:
  • Barco, Christie, NEC digital projectors
  • NCM, Screenvision, Broadsign and other preshow systems
  • Dolby, USL, QSC and other sound processors
  • Scalers
  • 3D Systems
  • Unique devices via a RAW Ethernet connection
  • Unique devices via a RAW Serial connection

The core JNIOR provides the capability to work with various digital cinema servers (Doremi, GDC, Christie, Dolby, Barco, Qube) to allow the JNIOR to act as GPIO (General Purpose IO) to control the lighting levels (low, medium, high), masking curtains (scope, flat), sound, doors and various other items.  The digital cinema server sends commands to the JNIOR to ‘pulse’ its relays to change the desired function.

When you add the Cinema.Jar application, it allows the JNIOR to become a central automation device capable of interacting with the digital cinema server, preshow systems, projectors, sound controllers, scalers and various other industry devices and systems.  The application integrates these devices and systems with the JNIOR via the Ethernet and/or serial ports. To see how to setup the serial connection for Cinema.Jar, click here.

Central to Cinema.jar is its ability to execute ‘macros’ on the JNIOR.  A macro consists of one or more ‘actions’.  An action can control a JNIOR relay or send a command to one of the external devices.  The external ‘devices’ and ‘macros’ are easily configured by using the JNIOR Support Tool.

Once the macros have been configured, the JNIOR is very flexible in providing a variety of methods to trigger a macro:

  • The digital cinema server or other client can send the ‘run macro name’ command.
  • A predefined ‘message’ can be sent by the client that will trigger a user-configurable macro name.
  • The JNIOR digital inputs can be configured to ‘trigger’ a specific macro when the input goes “high” (transitions from “off” to “on”).
  • A macro can be ‘scheduled’ to execute on boot-up of the JNIOR or at a specific time of day.
  • A macro can be triggered based on a ‘logical expression’.
  • The ‘switches’ on the JNIOR Control Panel can trigger a macro.

Perform a reboot from Java Application

When we want to reboot the JNIOR from our Java application we call the command line reboot command.  To call to the command line we use the ConsoleProcess class.  Since there will not be any user to confirm the reboot we need to use the -f command to force the reboot.

        try {
            // the -f option forces the reboot without the need for user confirmation
            ConsoleProcess consoleProcess = new ConsoleProcess("reboot -f");
            consoleProcess.waitPrompt();
        } catch (Exception ex) {
            throw new IOException("Error rebooting").initCause(ex);
        }

Finding the JNIOR IP Address

Sometimes you need to find out what the IP Address of the JNIOR is that is sitting on your network.  Sometimes someone else set it up and are no longer working with you or maybe you programmed it but years have passed and you haven’t needed to access the JNIOR because it is performing its job and no attention has been needed.

There are a couple of different ways to find out the IP Address.

By far the easiest way to find the JNIOR IP Address is the use the JNIOR Support Tool.  The JNIOR Support Tool only works on Windows systems.  http://jnior.com/category/news/support-tool/ will have links to the latest, as well as previous, versions of the JNIOR Support Tool.  Once loaded and started you will be presented with the Beacon tab.  The Beacon tab will show all the JNIORs that are present on your LOCAL network that have reported.  When the Support Tool launches a broadcast is sent out asking for all the JNIORs to report their information.  Some network configurations can either help or hinder this operation.  In most cases it works as intended.  Here is a picture of the Beacon screen.  If you have more than one JNIOR shown you can use the Serial Number of the JNIOR to identify which row corresponds to your unit or you can use the identify feature to pulsate the amber LED next to the power indicator.  To perform that function you can right click on a row and select either Query | Identify or Configure | Identify from the menu.

The other way to determine the IP Address of a unit is to directly connect a serial cable to the RS-232 port.  Computers do not come with serial ports anymore so a USB to Serial adapter will be needed.  You can find them at Amazon.  Once the cable is connected, select your favorite terminal application or use the Command Line application included with the Support Tool.  The serial settings must be 115200, 8, 1, none for the baud rate, data bits, stop bits and parity respectively.  Now that the connection is set up you can press enter and the login prompt will be presented.  The default credentials are username: jnior and password : jnior.  You can now enter ipconfig to see the current network setup.

 

 

 

 

 

 

 

 

Lastly, for those who know Morse code, you can unplug the network cable and the status LED will flash Morse code representing the value of the last octet.  You must know the first 3 octets of your network.

JMP Protocol

Available in JANOS 1.8.

Name Version Release Date Size MD5
JMP Protocol Manual v2.0 Mar 14 2024 230.0 KB 905f124811e438ea93ccd542bdd66f41

The JMP protocol shares the messaging JSON structure that is used by the DCP (Dynamic Configuration Page) and the web-socket protocol but on port 9220, by default.

To make processing easier we wrapped the JSON message in a two element JSON Array.

[ number, object ]

Where number is the size in bytes/characters of the JSON object that follows.

Doing this relieves us of needing to count braces to see when an entire JSON message was received. To parse the structure we can do the following:

  1. Look for the opening ‘[‘.
  2. Then process numeric values until a ‘,’ is found. White-space is ignored.
  3. White-space is again ignored and N bytes are read.
  4. Finally remaining white-space is ignored and the trailing ‘]’ confirmed.

If the numeric value is invalid, the comma missing or the trailing ‘]’ bracket not found, the entire message is to be ignored. The extracted JSON Object can then be validated as well.

Type28 is the temperature probe and Type7E is the environmental sensor.

To enable this you will need to set the AppData/Cinema/WebServer/Port registry key. The JNIOR will need to be rebooted after this key has been changed. In this example I chose 8081. Port 80 or 443 is normally the default web server port. This web server port is an additional web server that cinema is hosting to handle these types of requests.

Enabling MODBUS Server

MODBUS is a communications protocol used to communicate between a master and a slave or several slaves. The JNIOR implements MODBUS TCP. MODBUS TCP is the form for this protocol over the Ethernet network. The JNIOR acts as a slave by accepting requests and forming responses. Since Ethernet networks call devices clients or servers, the JNIOR is a server. Therefore the JNIOR has an application called MODBUS Server to handle the MODBUS TCP requests.

The MODBUS Server application is NOT enabled by default. It must be enabled before MODBUS masters or clients can send requests to the JNIOR. Once enabled the JNIOR will begin listening to TCP connections on port 502.

To enable the MODBUS Server you should go to the DCP (Dynamic Configuration Page).

Then navigate to the ‘Configuration’ tab.

Now, select ‘Applications’ halfway down the left side. Make sure the MODBUS Server application is checked

Once the application is checked it is then required you Reboot the JNIOR.

You can then optionally make a telnet connection to verify. The ps command to make sure the modbusserver application is running. Then you can use the netstat command to see that port 502 is listening.

Taking a Snapshot

Many times the best way to send diagnostic information to INTEG is to send us a Snapshot. A Snapshot is a zip file containing all of the files from the JNIOR.

When a Snapshot is taken the Support Tool will make a telnet connection, run a few diagnostic commands and then download all of the files. The diagnostic commands that are executed will be logged to the snapshot.log file.

There are two commands that will generate files that are not normally in the file system.

The first in the iolog command. The iolog command will generate a jniorio.log file. This file shows the past 512 digital input transitions as well as the past 512 relay output transitions. Up to 16 relay outputs will be shown in the log. The relays on the expansion modules will be logged as well.

The second command is the netstat -c command. This command generates a network capture file in the temp directory. The network capture file can be loaded in a desktop application called wireshark. This file will grow up to 512Kb. The duration of time covered by the file depends on the amount of traffic that the JNIOR handles. Optionally filters can be applied to the capture buffer to limit the types of traffic that are logged.

To take a snapshot follow these steps:

  1. Open the Support Tool. Go to the Snapshot tab.
  1. Click on ‘Take Snapshot’.
  1. Answer ‘Yes’ to the Snapshot confirmation dialog
  1. Select the JNIOR you want to take a Snapshot from and click ‘Ok’.
  1. Once your snapshot is compete find it on the left. It should be made visible once it is complete. Right click on the Snapshot file and select ‘Show in folder’. You could also expand the zip archive in the tree view or double click it to open in your loaded Archive application.

JANOS 1.8 Moved to Release Candidate

It’s been 5 months since the release of 1.7.1. We finally had a reason to touch JANOS. We implemented the JMP protocol. JMP (JANOS Management Protocol) is the same JSON messaging structure that is used in our weboscket protocol.
