You can easily update the Bundled applications on your JNIOR by downloading and installing the above update project. Download and open the .zip file in the JNIOR Support Tool.

The bundled software is easy to activate and deactivate from the JNIOR Web UI.  Go to the Applications section in the Configuration tab, check the box for the application you want to activate or deactivate. The setting will automatically be saved. You must reboot the JNIOR for the updated settings to take effect.


MODBUS is a legacy protocol that is still heavily in use today. It is a request/response protocol. The MODBUS Server application implements MODBUS/TCP and allows the user to interact with JNIOR I/O over the Ethernet network. The default MODBUS port is 502.

Serial Control Plus

Our Serial Control Plus application provides I/O control and status using simple ASCII commands. You can connect to the Serial Control Plus application serially via one of the two serial ports or an Ethernet port can be configured to accept the Ethernet connection.

Serial to Ethetnet Converter

The Serial-to-Ethernet Server application allows the JNIOR to act as a converter between a serial device connected to one of the JNIOR serial ports and a remote application communicating to the JNIOR via the Ethernet network using TCP/IP. The Serial-to-Ethernet conversion is bi-directional, meaning that the serial device can communicate to the Ethernet device and the Ethernet device can communicate to the serial device.

Slaving Service

Slaving allows you to assign local I/O to follow the state of other I/O channels.  The I/O point you are following can be another local I/O channel or a remote I/O channel.  Remote I/O channels can be accessed on one or more JNIORs. The I/O can also have a default state in case connection to a JNIOR that was being slaved to is lost.


SNMP allows you to view system information from an SNMP browser. The SNMP application uses the JNIOR MIB in order to query its data. Once you’ve opened the JNIOR MIB in an SNMP browser, you can enter its IP address to begin searching for different information from that JNIOR. You can also set standard or custom traps to receive notices when events occur on the JNIOR.

These applications have web pages created for them to make configuring them easier. To access the configuration web pages for these applications, you can do so by opening a web browser and entering the JNIOR’s IP address followed by /bundled. Specific web pages won’t display unless their related application is running on the JNIOR. These web pages let you configure registry keys for their related application. Here is a link describing the web pages in a bit more detail.
