Switching-off the Termination of the universal Clock Inputs
When iCLOCK is shipped, the BNC-based univer-
sal inputs are terminated internally with 75
Ω
.
Two Jumpers are put on two 2-pin sockets, J 41
for INPUT 1 and J 42 for INPUT 2.
Removing the jumpers from the two 2-pin
sockets will switch off the 75
Ω
termination for
the according universal BNC input connector.
We recommend to keep the jumpers to be able
to reactivate the termination for other applica-
tions!
Jumper:
CAUTION! Disconnect the unit from the mains before opening!
Remount the steel-plate cover thoroughly before you attempt to operate
the unit!

Splitting-up the Video Ouputs for dual
Video Generator Operation
When iCLOCK is shipped, the two BNC-based
video output pairs are transfering the video
signal of the internal video reference generator
simultaneously. Two Jumpers are put on two
2-pin sockets, J16 and J17.
Removing the jumpers from the 2-pin sockets
will split up the dual video BNC output connec-
tors for two video generators as follows.
VIDEO OUT 1 = internal video reference
generator
VIDEO OUT 2 = optional video generator
We recommend to keep the jumpers to be able
to reactivate the termination for other applica-
tions!
CAUTION! Disconnect the unit from the mains before opening!
Remount the steel-plate cover thoroughly before you attempt to operate
the unit!

Connecting the universal Clock Inputs to Ground
When iCLOCK is shipped, the BNC-based univer-
sal inputs are isolated from ground.
Setting the jumper one pin forward in direction
to the housing’s backside will connect the accor-
ding BNC input connector to ground. Both inputs
can be set independently.
