Connect the Communication Cables

RS-232 Connections

You can connect one clock to the host computer with an RS-232 connection. This is a basic connection using an RS232 serial cable.

See Appendix A for the RS232 cable diagram

To make an RS232 connection

Run your RS-232 cable from the back of the computer to the clock.

Attach the DB9 connector to an open 9-pin COM port on the back of your computer. (Note: Connect the RJ45 modular cable to the DB9/RJ45 adapter)

Insert the RJ-45 end of the cable through one of the knockouts on the clock’s back box.

Attach the RJ-45 plug to the Terminal’s RS232/RS485 communications port as shown in the diagram below, Figure 3.
