Troubleshooting Serial Communication Problems

General Notes ¥ Power up your computer or terminal BEFORE you power up the ZETA6104.

¥ Make sure the serial interface is connected as instructed on page 8. Shield the cable to earth

ground at one end only. The maximum RS-232 cable length is 50 feet (15.25 meters).

¥ RS-232: Handshaking must be disabled. Most software packages allow you to do this.

You can also disable handshaking by jumpering some terminals on the computerÕs/

terminalÕs serial port: connect RTS to CTS (usually pins 4 and 5) and connect DSR to

DTR (usually pins 6 and 20).

¥ RS-485: Make sure the internal DIP switches and jumpers are configured as instructed on

page 5.

Test the Interface 1. Power up the computer or terminal and launch the terminal emulator.

2. Power up the ZETA6104. A power-up message (similar to the following) should be

displayed, followed by a prompt (>):

* PARKER COMPUMOTOR 6104 Ð SINGLE AXIS INDEXER/DRIVE

*RP240 CONNECTED

3. Type ÒTREVÓ and press the ENTER key. (The TREV command reports the software

revision.) The screen should now look as follows (if not, see Problem/Remedy table

below).

*PARKER COMPUMOTOR 6104 Ð SINGLE AXIS INDEXER/DRIVE

*RP240 CONNECTED

>TREV

*TREV92-014630-01-4.7 6104

Problem Remedy (based on the possible causes)

No Response ¥ COM port not enabled for 6000 language communication.

If RS-232 connected to COM 1: issue ÒPORT1Ó and ÒDRPCHK¯Ó commands.

If RS-232 connected to COM 2: issue ÒPORT2Ó and ÒDRPCHK¯Ó commands.

If RS-485 connected to COM 2: issue ÒPORT2Ó and ÒDRPCHK¯Ó commands.

¥ RS-232: Echo may be disabled; enable with the ECHO1 command.

¥ If you are using an RS-232 connection between the host computer and the master

ZETA6104 connected to multiple ZETA6104s in an RS-485 multi-drop, make sure

the master ZETA6104 has these settings executed in the order given (you should

place these settings in your power-up STARTP program):

PORT1 (select RS-232 port, COM1, for configuration)

ECHO3 (echo to both COM ports)

PORT2 (select RS-485 port, COM2, for configuration)

ECHO2 (echo to the other COM port, COM1)

¥ Faulty wiring. See instructions on page 8. RS-485: verify internal DIP switch and

jumper settings on page 5. Also check for shorts or opens.

¥ Is the cable or computer/terminal bad? HereÕs a test:

1. Disconnect the serial cable from the ZETA6104 end only.

2. Connect the cableÕs Rx and Tx lines together (this echoes the characters back

to the host).

3. Issue the TREV command. If nothing happens, the cable or computer/terminal

may be faulty.

¥ The controller may be executing a program. Issue the !K command or the

<ctrl>K command to kill the program.
