3.7. Interconnection
The following figure shows the PDS3000C01 module rear board connector layout.
Rear view of the PDS3000C01
The PDS3000C01 provides one digital video reference input (SDI REF) and two digital
video outputs (SDI OUT1 y SDI OUT2). The connector labeled SDI OUT1 is protected by the
bypass relay such that continuity of the reference input signal is maintained in case of a
power supply failure or extraction of the module. The module also has two connectors
with loop-through for analog video (CCVS IN), and if only one is used then the other
should be terminated with a resistance of 75Ω. In addition the module has an output
(VID DELAY) that delivers pulses with a duty cycle proportional to the delay between the
input and output. Finally, the module has two GPIOs, (IO1 and IO2).
The rear interconnection board is not designed to withstand mechanical stress. The
wiring must be fastened properly to the frame where the mounting frame is housed to
prevent the rear board from supporting the weight of the cables.
