Response Data (conditional): The following sections describe the response of the 13x to commands that
require it to send data (all data described below follows a transmission Header identical to that described
above).
Channel Setup Data - The data sent in response to the ‘Setup from 13x’ command (0x02) is identical to
the format of the Setup to 13x’ command (0x00) described above. If the channel number indicated in the
header equals zero (0) then data will be sent for all three channels.
Calibration Constant Data - The data sent in response to the ‘Cal Constants from 13x’ command (0x03)
is identical to the format of the Cal Constants to 13x’ command (0x01) described above. If the channel
number indicated in the header equals zero (0) then data will be sent for all three channels.
Calibrated Vout Data - The data sent in response to the ‘Calibrated Vout Data ‘command (0x04) will be
for the channel indicated in the transmission header. If the channel number equals zero (0) then data will
be sent for all three channels. The transmission of data for the indicated channel(s) will continue at the
rate specified by the ‘Data Interval to 13x’ command. The data will be one or three values formatted to be
a decimal integer string. To render it back to a floating point number it should first be converted from a
string to an integer and then divided by 1000.
NOTE: If the unit is not in the ‘Normal’ mode of operation at the time it is scheduled to output
data remotely, that data transmission will be skipped.
Raw Vout Data - The format of the data sent in response to the ‘Raw Vout Data ‘ command (0x05) is
identical to the Calibrated Vout Data discussed above.
Unit ID Data - The data sent in response to the ‘Unit ID from 13x ‘ command (0x09) is a string which
states the Model number and the firmware revision (i.e 133 REV A).
