5. Connect the remote monitor and RS232 to the receiver unit and
attach the power supply to the receiver
CAUTION
Before plugging in the remote monitor, verify that the AC line is properly
wired and that a protective ground (green) wire is established with NO
potential difference between both the sender and receiver locations. The
splitter can tolerate up to 5 v peak-to-peak ground potential between the
two locations. Failure to ensure good grounding can result in erratic
operation and possible shock hazards or damage to your equipment.
NOTICE
Do not connect this unit to any LAN device such as network cards or hubs
as this may damage the UV232/UR232 and/or the LAN device. Use EIA/TIA
568B standard straight-through patch wiring as shown below. Do not use
crossover cables.
