WRITE/READ BITS (Range, Filter and Channel 3/4 Connect Register)
These bits set the gain of the input channel by the codes shown below:
000 = 62.5 mV range
001 = 0.25V range
010 = 1.0V range
011 = 4.0V range
100 = 16V range
101 = 64V range
110 = 256V range (also 111 = 256V range)
These bits connect an internal short to the channel inputs when the bit is "1". When it
is "0", bits 7 & 15 connect the channel to the input or the calibration bus.
These bits set the input channel filter cut-off frequency by the codes shown below:
000 = 1.5 kHz
001 = 6 kHz
010 = 25 kHz
011 = 100 kHz
111 = NO filter
This bit connects the input channel to the front panel connector (Connect Code = 0) or
to the calibration bus (Connect Code = 1).
This register provides 8-bit data corrected for offset and gain in 2's
compliment format.
