MMI Product Documentation
The Events Buss allows the Controller to receive and/or transmit discrete events in time. The XMT and REC LEDs indicate whether the OPTOMUX is transmitting or receiving data. (These LEDs should never be on at the same time.) This actual input/output switching is executed by the OPTOMUX board: see “Setup and Configuration” or “Programmer Operations” or the OPTO22 manual for specific details.
