VGA SOURCE AND DISPLAY BALUNS
3. Installation
To install the VGA Balun, follow these steps:
CAUTION
Do not attempt to open the housing. There are no user-serviceable parts
inside the balun. Opening the unit will void your warranty.
1. For reliable signal continuity between the equipment, use shielded twisted-
pair (STP) cable terminated with shielded RJ-45 connectors.
2. Since the VGA Balun does not support VGA handshaking and control signals,
set the monitor attributes before installing the VGA Baluns. To do this, first
connect the standard VGA cable directly from the PC to the monitor. Then
set the monitor attributes to the required settings (resolution, color, etc).
Also, to achieve optimum results via twisted pair, set the Contrast and
Brightness levels to maximum.
3. Turn off the power and disconnect the PC and VGA display equipment by
following the manufacturer’s instructions.
4. Make certain that modular outlets and cross connects to which you will
connect the VGA Balun are configured properly and labeled appropriately to
identify the circuit.
CAUTION
Do not connect the VGA Balun to a telecommunication outlet wired to
unrelated equipment. Making such a connection may damage the
equipment and/or the balun. Make sure that all wiring is “straight-
through” twisted pair.
5. Verify that the desired twisted pairs are not being used for other LAN or
telephone equipment.
NOTE
The baluns operate in pairs.
6. Connect the VGA Source Balun (AC640A) to the PC’s or VGA
splitter/booster’s VGA port. Tighten the mounting screws on each balun.
CAUTION
Do not mount the balun over equipment ventilation openings. Covering
the openings may cause the equipment to overheat.
