DB9 Pinouts
- DTE stands for “Data Terminal Equipment.” DTE include computers, PLC’s, and most devices which are not used to extend communications. (Think COMPUTER for DTE.)
- DCE stands for “Data Communications Equipment.” DCE includes devices intended to plug directly into a DTE port; modems or devices that extend communications like a modem, such as RS-422, RS-485, or fiber optic converters or radio modems. (Think MODEM for DCE.)
- On the DCE (female) side, Pins 1, 4, and 6 are tied together internally.
- On the DTE (male) side, Pins 4 and 6 are tied together internally.
Wiring Example
Power
- The two sides of the isolator are powered from a single +12VDC power supply and maintain isolation. This powering configuration allows the device to be run in any system with only a single power supply, regardless of the power levels on the RS-232 ports.
- In order to maintain the required isolation, use the recommended power supply. Using an unregulated power supply may negate the isolation.
- Recommended power supply: Model SMI6-12-V-P230-C1 (available from Advantech B+B SmartWorx).
Loopback Test
- Use a DB9 female to DB9 male cable to connect a PC to the DCE port.
- (Recommended) Connect a DB9 female to DB9 female cable to the DTE port.
- On the DTE Port, jumper Pin 2 to Pin 3 and Pin 7 to Pin 8 on the female end of the cable. This loops TD to RD and CTS to RTS.
- Using hyper-terminal or a similar program, connect to the appropriate COM port (remember to set the baud rate to 9600).Turn off hyper terminal local echo
- Transmit data. The same data should be returned.
