PC Communications Configuration Laptop computers must be properly configured to communicate with the payload meter. Often times the wrong serial port is set, or old software is being used that is not compatible with newer computers. Verify the correct serial port is set for your laptop. The most common port available on a laptop is serial port 1. It is sometimes labeled as COMM1. Occasionally, installed software on the laptop will take command of the serial port and not let the download soft- ware have access to the port. Software used by Palm Pilots, Handspring Visors, Pocket PCs, and other Personal Digital Assistant (PDA) devices monitors the serial port for connections.
When this software is active, the download software cannot use the serial port and cannot download the payload meter. Ensure this software is not running when attempting to download data from the payload meter. M20007.2 3/02 Payload Meter II™ Troubleshooting M20-41
