Serial Communications Problems

1.Test your terminal or terminal emulation software. Disconnect the motor and transmit a character. Receiving double characters (XX) when entering single characters (X), indicates your computer is set to the half duplex mode. Change to the full duplex mode.

2.Host transmit (TX) must be connected to receive (RX) of the drive unit, and receive (RX) of the host must be connected to transmit (TX) of the drive. If communication fails, try reversing these connections at either the host or the LinStep.

3.Many serial ports require handshaking. Jumper RTS to CTS, and DSR to DTR at host connector Jumpers 9 pin (25 pin) RTS to CTS 7 to 8 (4 to 5); DSR to DTR 4 to 6 (6 to 20).

4.Configure the host to the identical baud rate, number of data bits, number of stop bits, and parity.

5.Check all grounds. Use DC common or signal ground as your reference. Do not use earth ground or shield.

6.Check your cable length. If any cable is over 50 ft. long, you should be using a line driver, optical coupler, or shield. Shields must be connected to earth ground at one end only.
