If all four input channels are being driven, we see that the value that
appears at address #1 is the rate of the signal that appears at swingarm
terminals 3 and 4. Note that the value that appears at address #3 is the rate
of the signal that appears at swingarm terminals 6 and 7; the value
appearing at address #5 is the rate of the signal that appears at swingarm
terminals 9 and 10; and finally, the value that appears at address #7 is the
rate of the signal that appears at swingarm terminals 12 and 13. The totals
for each of the channels appear to the right of their respective rates; i.e.
channel 1 rate (word #1) is accompanied by channel 1 total (word #2);
Channel 2 rate (word #3) is accompanied by channel 2 total (word #4);
Channel 3 rate (word #5) is accompanied by channel 3 total (word #6); and
channel 4 rate (word #7) is accompanied by channel 4 total (word #8). The
acknowledgement code of 1000 (in word 0) identifies the module as
1771–QRD Pulse Flowmeter Module.
