Group Commands for Four 8-bit Channels: 7000
hex
and 7100
hex
With commands for four channels, the analog values for two channels are mapped to every input
word. The measured value for each channel is represented in eight bits. This measured value corre-
sponds to bits 15 to 8 in the format displays of a 16-bit value.
Example 4 x 8-Bit Group A (Channels 1, 2, 3, and 4): 7000
hex
