VGA Wiring
Recommended cable for VGA purpose is Carlisle P/N 453005 (formerly ECS). This is a single
shielded cable containing 5 separate coaxial cables, color-coded to match the functions of the
wires.
We recommend coax cables be terminated using solder sleeve coaxial cable terminators such
as Raychem Part Number CWT-4174-W122-5/9.
Power and Ground Wiring
The rated current of the equipment and associated voltage drop should be taken into
consideration when selecting wire gauge. The following example is based on an install with a
28VDC power system, 1.5 amp equipment load and a total of 50 feet of wire between the
circuit breaker, monitor and ground.
Example: 22awg wire has 16.2 Ohms per 1000 feet, this equates to .81 Ohms for 50 feet. 1.5
Amp of current on .81 Ohms will drop 1.22 Volts.

Also, use short heavy gauge wire and a clean tight connection for ground.
It is the installer's responsibility to understand the product's requirements in order to install the
product in compliance with industry standards and safety.
