CHAPTER 3
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.
