Serial Configuration Interface (RS232)
RS232 interface is used only when the required basic network configuration setup is
being done.
Use a serial null modem cable with a 9-pin D-SUB connector. It is recommended to use
a short length cable for RS232 interface in order to maintain full communication speed.
RS232 interface connector is located on the front panel of each CPU card.
Important - RS232 connector is used only when the required basic network configuration
setup is being done. Therefore, the cable should not be connected to RS232 connector at
any other time.
