Connector Cap Removal
18
For streaming data through SDI and
supplying external power, remove
the connector cap (A) located below
the "tail" section by using the
provided T6 Torx tool.
For stand alone use, place the
A
connector cap back in the slot and
tighten by hand without excessive
torque.
This cap provides basic sealing and
protection for the SDI and power
connectors.
