The Pulse Output Block allows you to control multiple outputs at the same time. The Channel Mask allows you to select which channels will be set to the given State Mask. The State Mask and Channel Mask accept a binary mask. This can be represented as decimal or hexadecimal. To specify the mask as hexadecimal simple put '0x' before the value. For example, the decimal value of 128 equals output 8 which is also equal to hexadecimal 0x08. The Duration field set the duration of the pulse.
