Troubleshooting
Are My Devices Wired As DTE or DCE?
How to Check:
1. Use Rule of Thumb - If the device plugs into
the computer serial port and works normally,
the device is wired as DCE (or the connection cable
is a crossover type that makes it work as a DCE).
If the device connects to the computer port using
a “null modem” crossover cable, it is wired as DTE.
2. Use RS-232 Line Tester - A quick and easy way
to determine the DTE/DCE port type is to use
a RS-232 line tester such as the 9PMTT. The tester
can show the signal state of any active RS-232
data lines using LEDs lighting Red or Green.
Active data lines are output from a device.
They may be either High or Low.
