The three connector test units provide the ability to monitor any baud rate of Async data in both directions in a simplex mode, not Tx and Rx at the same time, between two devices such as a computer and modem. The data can be monitored with a computer using Procom, HyperTerminal or similar communications software using only one serial port on the monitoring computer. The data flowing between the two devices is OR together and connected to the Rx input of the MONITOR connector. The three connectors are wired in the conventional RS232 manner. The INPUT and OUTPUT connectors are connected pin per pin together. |
