A DTE device is “Data Terminal Equipment.” This includes computers, PLCs, and most devices that are

• Use a DB9 Female to DB9 Male cable to connect a PC to the DCE port. (Recommended)

Loopback Test

not used to extend communications.

• Connect a DB9 Female to DB9 Female cable

(Think “COMPUTER” for DTE.)

A DCE device is “Data Communications

to the DTE port. On the DTE Port, jumper pin 2 to 3 and pin 7 to 8 on the female end

of the cable. This loops TD to RD and CTS to RTS. Equipment.” This includes modems and other devices that extend communications, like RS-422, RS-485, ber optic converters or radio modems.

• Using HyperTerminal or similar program, connect

to the appropriate COM port. (Remember to set

the baud rate to 9600.) (Think “MODEM” for DCE.)

• Turn off HyperTerminal local echo. When connecting a DTE device to a DCE device, use a straight through connection. When connecting a DTE device to a DTE device, or a DCE device to a DCE device, use a crossover (null) connection.

• Type some characters in HyperTerminal. The

same characters should appear on your screen. The LED indictors will light up to show you that data is being transmitted.

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.
