Problem Remedy (based on the possible causes)
No Response • COM port not enabled for 6000 language communication. Issue the “
PORT1
”
command and then the “
DRPCHKØ
” command.
• Echo may be disabled; enable with the
ECHO1
command.
• Faulty wiring. See instructions on page 7. Also check for shorts or opens.
• Is the cable or computer/terminal bad? Here’s a test:
1. Disconnect the serial cable from the 6200 end only.
2. Connect the cable’s 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.
Garbled Characters • Verify setup: 9600 baud (range is 9600-1200—see AutoBaud, page 4),
8 data bits, 1 stop bit, no parity; Full duplex.
• Faulty wiring. See instructions on page 7. Also check for shorts or opens.
Double Characters • Your terminal emulator is set to half-duplex; set it to full-duplex.
Product Return Procedure
Step 1
Obtain the serial number and the model number of the defective unit, and secure a purchase order number to
cover repair costs in the event the unit is determined by the manufacturers to be out of warranty.
Step 2
Before you return the unit, have someone from your organization with a technical understanding of the
6200 system and its application include answers to the following questions:
• What is the extent of the failure/reason for return?
• How long did it operate?
• Did any other items fail at the same time?
• What was happening when the unit failed (e.g., installing the unit, cycling power, starting other
equipment, etc.)?
• How was the product configured (in detail)?
• Which, if any, cables were modified and how?
• With what equipment is the unit interfaced?
• What was the application?
• What was the system environment (temperature, enclosure, spacing, contaminants, etc.)?
• What upgrades, if any, are required (hardware, software, user guide)?
Step 3
