Cable Recommendations for Female DB9 Connector (older)
The recommendations for the older female DB9 connector are the same as for the male DB9
connector, but the gender on the RMC-end of the cable must be reversed:
• Generic null-modem (female on both ends) serial cable with a 9-pin female-to-male gender
changer
• Allen-Bradley PLC Serial Cable with a 9-pin female-to-male gender changer
• Modicon Modbus cable
• Siemens SIMATIC 505 Programmable Controller Serial Cable with a 9-pin female-to-male gender
changer
• You can build an RS232 cable using the diagram above, except the gender of the RMC-end
connector should be reversed.
• Any other cable you have will work if you can verify that pins 2, 3, and 5 on the RMC-end of the
cable are connected as shown in the above diagram. An Ohmmeter or continuity checker will
work for verifying the cable connections.
