6 Service and Maintenance 6.12 IEEE 488 Troubleshooting If your interface fails to function, first verify the following: 1. Switch settings. Be sure the vacuum system controller knows the address of the 360 as set by the dip switches. Be sure the vacuum system controller does not reserve certain addresses for system devices, e.g., a printer. Be sure the 360 is not in the talk-only mode unless desired for data logging. Be sure, if the SRQ mode is set, that your controller performs a serial poll in response to the SRQ from the 360. 2. Check interface wiring. Be sure the cable is good; try swapping in a known good cable (IEEE 488 cables are available from G-P). Check for too many devices on the bus or too great a total bus length (> 20 meters). Too many devices could cause problems due to capacitive loading. 3. Check command syntax. Be sure you are following the syntax specified in Section 4.13 on page 4-31. Table 6-7 IEEE 488 Troubleshooting Guide. Symptom Micro-controller reset LED lit. OVERRUN ERROR message. SYNTAX ERROR message. No response. Possible Cause Micro-controller failure. Host software failure. Message to 360 not in accord with syntax. Incorrect address setting. Bad cable. 6.13 Field Installation of Modules 1. Turn off power. 2. With power off, remove any cables from the Control Unit rear panel. 3. Observe antistatic precautions to avoid damaging static sensitive components inside the chassis. Use a grounded, conductive work surface. Do not handle MOS devices more than absolutely necessary, and only when wearing a high impedance ground strap. Use conductive envelopes to store or ship MOS devices or printed circuit boards. Do not operate the 360 Controller with MOS devices removed from the printed circuit boards. 4. See Section 2.1.1 on page 2-2 for how to remove the top cover. 5. Locate correct position for module. 6. Carefully remove the bus ribbon cable from all modules located to the right (as you face the front panel) of the position where the module is to be installed. Remove connectors slowly using pull tabs. 7. Lift out the filler module at the position where the module is to be installed. 8. Install the module in its proper position making sure all ends lock together. 6-10 Series 360 Stabil-Ion December, 2001
