SDI
Pin Function
A SDI power out
B SDI data
C Ground
POWER OUT:
Current limited to approximately 750 mA. Short duration transients
of higher current can be supplied without triggering the limit.
SDI DATA:
Bi-directional SDI communications (standard 0-5 Vdc).
Version 1.1 supported.
GROUND:
Standard SDI power and signal ground.
NOTE:
If running long cables to a SDI sensor, it is very important that the wire gauge be
large enough to minimize voltage drops due to the sensor operating current. As a
rule of thumb, do not let there be more than 0.5 V drop due to cable resistance in the
power and ground lines. The ground line is the most important, the signal line is not
important.
PROGRAMMING SUPPORT:
SDiV: The voltage present on pin A with respect to pin C.
