7.1.1 Comm. commands for DTM Host and Measurement Expansion Module
1. Before turning on power to the DTM host, first set dip switches, station number addresses, and all
attribute expansion module station number addresses.
2. Function code (Function): H03 = read the register content, up to 64 words; H06 = write a word to the
register; H10 = write multiple words to the register, up to 64 words.
See the table below for communications function addresses and their content: (x represents the internal
station number, x=0 indicates the DTM host)
