Cannot Download - PC Communications The most common problem with PC communications to the payload meter is configuration of the PC. Be sure the correct serial port is selected for your laptop. In addition, be sure you have the latest PC software by checking with your distributor. Verify the payload meter is using the proper OP setting. Refer to “Setting the Option Code” for information on OP settings. No body-up input signal can be perceived as a communication problem with the payload meter. Without the body- up signal, the payload meter never starts a new haul cycle.
When the payload meter is downloaded, and no haul cycles have been stored in memory, a technician may assume that the laptop did not communicate with the pay- load meter. M20-40 Payload Meter II™ Troubleshooting M20007.2 3/02 ?
