Output Data File
For each module, slot x, words 0 through 3 contain the channel output data.

Words 0 through 3 contain the analog output data for channels 0 through 3, respectively. The
module ignores the "don't care" bits (0 through 2), but checks the sign bit (15). If bit 15
equals 1, the module sets the output value to 0V or 0 mA.

Words 0 through 3 contain the analog output data for channels 0 through 3, respectively. The
module ignores the "don't care" bits (0 and 1), but checks the sign bit (15), and bit 14. If bit
15 equals 1, the module sets the output value to 0V or 0 mA. If bit 15 equals zero and bit 14
equals 1, the module sets the output value to 10.5V dc or 21 mA.
