2.Confirm that the host and peripheral are configured for the same baud rate, 8 data bits, 1 stop bit, and no parity.

3.Use DC common or signal ground as a reference, not earth ground.

4.Cable lengths should not exceed 50 ft. unless you are using some form of line driver, optical coupler, or shield. As with any control signal, be sure to shield the cable-to-earth ground at one end only.

5.To test the terminal or terminal emulation software and the RS- 232C cable for proper three-wire communication, unhook the OEM650X and enter a character. You should not receive an echoed character. If you do, you are in half duplex mode. Con- nect the host’s transmit and receive lines together and send another character. You should receive the echoed character. If not, consult the manufacturer of the host’s serial interface for proper pin outs.
