RS232 Monitoring

Post by xol »

To monitor half-duplex RS232 communication with SUB-20 (or PC) you can use Monitoring Dongle presented below. Dongle has 3 DB9 connectors. Left and right are pass through connectors and bottom one is a monitor connector. The data passing between pins 2 and 3 of the left and right DB9 connectors in both directions can be viewed at the bottom connector at pin 2.
