Pgui32 Setup And Installation; Figure 8-3: Rs232C Interface Cable Wiring Diagram - Ametek 2003RP User And Programming Manual

8.4.2 Serial Cable Diagram
California Instruments AC power sources require a special RS232C cable to communicate
with a PC. Standard null-modem cables obtained from a computer hardware store most
likely will not work. For this reason, all California Instruments power sources that operate
over RS232C are supplied with a RS232C 9 pin female to 9 pin female cable.
If for some reason this cable cannot be located, the cable diagram shown in Figure 8-3
should be used when constructing a serial cable.
