NOTE:  Configuration numbers 2 & 4 have transmit (Tx) on the same control port (c+1). This is
useful if you plan to initialize the SC100 and receive data without having to change the control port
functions.

Choosing value for bit3 (half/full):

1) If the half duplex version and configuration

number 2 or/and 4 are used, then bit3 must
be 1.

2) If the full duplex version and configuration

number 2 or /and 4 are used, then bit3 must
be 0.

3) If configuration number 1 is used, then bit3

must be 0 for either half or full duplex.

Bit2 (parity/none) when this bit is set to one,
then either even or odd parity (depending on bit
4) will be enabled for the computer/sensor side.

Power Down wire (+5 V will power
down the SC100 if internal jumper is
connected, connect to gnd if not
used).  There are three different
power modes.
1) Yellow wire tied low (gnd) normal

operation mode ~55ma.

2)  Yellow wire high (+5 V), Red wire

+12 V, power down mode ~ 2ma

3) Yellow wire high (+5 V), Red wire

+5 V power down mode  >50
