The Torpedo SOM hardware uses a different
nomenclature in the documentation. The SOM
serial port (A, B, C) maps to the SLA serial port (0,
1, 2).
Used for:
Command and Control
and debug. Recommend
allowing access for
troubleshooting.
Command and Control
and general customer
use/passthrough.
Primarily camera control
passthrough, can be used
for general customer

J1 is FFC ribbon to Tau camera.
Voltage levels set by Tau camera so only 3.3 V
when camera is connected.
IMPORTANT
: To use serial port 1 and serial port 2, external power must be applied to VIOSEL (OEM
J4 pin 46) to set the IO voltage level. Connecting to camera interface boards and cameras sets this
IO voltage level.
