Model 2790 SourceMeter
Channel number — The channel number indicates the switching module channel for the
reading. Channel number 000 indicates that no system channel was closed.
Limits — For the ASCII data format, limit test results are returned as a 4-bit binary num-
ber "abcd" where:
a = High limit 2
b = Low limit 2
c = High limit 1
d = Low limit 1
A "0" indicates that the limit has passed, while a "1" indicates that the limit has failed.
For the binary data formats, the limits information must be decoded from the returned
value (0 to 15). Convert the value to its binary equivalent for "abcd" where "d" is the LSD
and "a" is the MSD. For example, the value 10 converted to its binary equivalent is1010.
That means High Limit 2 and High Limit 1 have failed.

Parameters
For normal byte order, the data format for each element is sent as follows:
Byte 1
Byte 1
For reverse byte order, data is sent as follows:
Byte 4
Byte 8
The "#0" header
at the beginning of the data string for each measurement conversion.
The ASCII data format can only be sent in the normal byte order. The SWAPped selection
is ignored when the ASCII format is selected.
