VISTEK V165X serial digital
video router module
HU-V165X
5
REF
The reference input is an analogue video signal of either 1Vp-p video or upto 4Vp-p mixed sync pulses. The
signal is passed through the rear module and terminated in 75 Ohms on the input router module.
SD (OUT) & SD1-8 (OUT)
The outputs are driven directly through the rear module from the input or output router module at 75 Ohm
impedance.
MON (OUT)
The monitoring output is driven directly through the rear module from the input router module at 75 Ohm
impedance. This output monitors the output busses of the crosspoint ic and not the inputs to the crosspoint.
DART Remote Control
The DART control interface is picked up by the input rear module from the rack and routed into the input
router module.

Hardware
The figure below shows diagramatically the input module, which contains all the control hardware and link
selectable variations. Not all components are fitted in every variant, (see text for details). The 8 Output
module has no links and is therefore not shown.

Switch and Link Settings
R102 & R103
These two resistors are used to control the routing of the signal on input eight to determine if the reference is
used or SDI input eight. The modules are shipped in the following configurations:-
V1651
R103
Reference Input.
V1652
R102
SDI Input eight.
V1653
R103
Reference Input.
V1654
R102
SDI Input eight.
