5.5.3. Transmitting Case Data to a Computer
The following instructions explain how to transmit case data to a computer using a null
modem cable and a terminal emulation program such as Tera Term™* or HyperTerminal™*
programs.
Data is transmitted approximately once every second as the case progresses. Data can be
transmitted in two formats: PC LINK 1and PC LINK 2. Instructions for selecting a format are
provided in the monitoring system's service manual. See Case Data Downloaded via Serial
Port, page 83 for descriptions of the formats.
5.5.3.1. Null Modem Cable Requirements
A 9-pin to 9-pin null modem cable is required for transmitting case data to a computer via
the serial port.
The null modem cable must be no longer than 50 feet (15.24 m).
