Note 1: mil is milliseconds for ASCII, but microseconds for binary (2-hexidecimal) output format.
Data output formats differ slightly from data input formats in that binary formats may be used for Channel Data.
Channel Data is the only output data which may use the binary format (if it is specified). Channel Data is defined
as data originating from the High/Low/Last (HLL) Registers or the Acquisition Buffer. The commands that initiate
Channel Data output are the
as Engineering Units and Counts.
Data output formats for command queries will follow the same rules as data input formatting. As in the case of
data input formats, all readings output will be in Engineering Units unless Counts is specified. However, there
are only 3 command queries which need to follow the
command queries.
