PC COMMUNICATION PROTOCOL % 1. Scope This protocol is to help 19-1108 communicate with optional device by user. 2. General This protocol consists of download section and upload section. ^ Download section is to transmit the data from PC to 19-1108 and upload section is to transmit from 19-1108 to PC. Data transmission should be through RS mtsh232 port. Please, read this documents carefully to communicate with the processor of 19-1108. 3.
