Note: Only sample mode 2 is supported on the A724 Series 4 RTU.
RETURNS A data block of io-port, raw adc and counter values.
REMARKS GET only. The command needs a certain delay to execute (for
example, for the standard SST setting this delay amounts to two
seconds). The delay is necessary to allow for the sensors to settle
after applying power to them.
REMOTE No.

The first column is the channel number. Channel 0 uses the internal
sensors such as temperature and battery voltage. Channels 1-4 are
the virtual connectors IO-A through IO-D. The four counter inputs of
the A724 Series 4 are mapped to virtual connectors IO-A through IO-
D, although the A724 Series 4 has only one sensor connector (INPUT).
Column 6 of channel 1-4 are the counter values. The analog input is
mapped to column 3 of channel 1. In the above example, the analog
value is 64 and counters 1-4 have a count of 9, 12, 1890, and 19
respectively. The actual valve state is displayed in column 2. The
decimal value 240 shows that all four valves are inactive
(high=inactive).
Note: The number 240 displayed in binary form is 11110000, which means
bits 7 to 4 are high.
