Cable Pin Assignments
In a serial communications connection, generally a computer is DTE (Data Terminal Equipment) and a
modem is DCE (Data Circuit-terminating Equipment). The ZyWALL is DCE when you connect a computer
to the console port. The ZyWALL is DTE when you connect a modem to the dial backup port.

The CON/AUX port also has these pin assignments.
The CON/AUX switch changes the setting in the

port’s pin assignments. ZyWALLs with a CON/AUX port also have a 9-pin
adaptor for the console cable with these pin
assignments on the male end.
