Console Access
14.1
RS232
The console is accessible via an RS232 interface for direct connection to a
computer’s serial (COM) port. This is performed by connecting the unit’s
RS232 port to the computer’s serial port via a standard straight-thru serial
cable. Unless the ARP ping configuration method is used, this will typically be
the initial configuration channel, as the telnet and web browser interfaces can
only be accessed once the network parameters have already been established
and the device is communicating on the Ethernet network.
14.1.1
Requirements
All that is needed is a computer with a serial (COM) port containing some sort
of communications software (such as HyperTerminal, included with Microsoft
Windows operating systems) and a straight-thru serial cable, such as the Belkin
6’ serial extension cable (Belkin part #F2N209-06). Refer to Figure 6 for a
representative example cable. Any communications software and PC will work,
provided they support ASCII communications at 38.4kbaud.

14.1.2
Connection
Connect one end of the serial cable to the gateway’s RS232 port, and connect
the other end to the computer’s serial port. Make sure that CFG DIP switch #2
is in the “OFF” (left) position to force the RS232 port to act as the serial
console. If the unit is currently using the RS232 port for control protocol
communication, then it must be rebooted (powered down and then back up
again) with CFG switch #2 in the OFF position to enable the serial console on
the RS232 port.
