they must be placed far away, compensate for losses of the long coaxial cable by increasing the cable
compensation setting by one click for each 200 feet of coaxial cable length (see diagram below). For example,
if the coaxial cable length from source to 9871 Driver is 220 feet (1 click) and the Cat 5 cable length to a certain
wallplate is 250 feet (2 clicks), the correct Cable Length Compensation for that wallplate is 1 + 2 = 3 clicks.
Conditions vary, so it is best to verify settings using the video display that will be installed in each location.
Connecting to an IR network
The DuoDrive does not have an IR remote control system; it provides a discrete three-strand Cat 5 pathway
for a third party system. Connect an IR remote control system input to the Driver IR output stereo 3.5mm jack
(see example diagram below). Connect an IR receiver to each wallplate/receiver and position them appropriately
in the rooms. Do not connect any equipment to the vacant white RCA jacks marked “IR”.
