WFM 601i Serial Component Monitor
Installing the WFM 601i in a Serial Video System
The serial digital monitor can operate almost anywhere in the distribution system
due to its high impedance, bridging, loop-through design. The following
describes two specific connections.
Most serial equipment employs a receiver and then later regenerates an output
signal. Routing the incoming serial signal through one of the loop-though inputs,
while connecting the output of the device to the other loop-through (for either
further distribution or termination) allows a check of both the incoming signal
and the equalized regenerated output signal. See Figure 1-8.

The WFM 601i can also be used to check serial digital signals around a routing
switcher. It is possible to look at all the inputs to the switcher with the use of a
patch panel and the serial monitor. See Figure 1-9.
