The setting of the eight contrast temperature bins is initially done at
Campbell Scientific. Below are the contrast settings of one type of
LCD screen for temperatures from <-15 to >+50 °C. A user can also
adjust the value of the current bin by entering the * D mode while in
Remote Keyboard Mode. The minimum contrast setting is 0. The
maximum setting is 255.

S
Returns Mode A Memory Allocation registers (first group of 01: to 09:)
and Mode B Status/On-board Firmware registers (second group of 01:
to 17:)

SDM-SIO4 talk through command
Address: Port T
Address = 0..15
Port = 0..4
nnnnU
Returns V[value] C[checksum] where nnnn refers to an input
location, port, or flag, V is the value at the input location, port or flag,
and C is the checksum. For nnnn = 90ff, then nnnn refers to flag ff.
For nnnn = 91pp, then nnnn refers to port pp. For nnnn<9000, then
nnnn refers to input location nnnn.
Examples (xxxx is checksum, true or high for flags is non-zero, false
or low is zero):
2U
V+73.650 Cxxxx. (input location 2 equals 73.650)
9003U
V+1.0000 Cxxxx (flag 3 is high).
9107U
V+0.0000 Cxxxx (port 7 is low)
nnnn:[value]:[checksum]U
Loads the input location, port, or flag referred to by nnnn with value if
the checksum is correct. nnnn refers to input location, flag, or port
as above. The datalogger returns the same as the nnnnU
command.
