Quick Installation Guide
Introduction
The VideoEase Active CCTV Transmitter Balun (500100, 500101) provides enhanced
performance for a single CCTV video channel via Cat5 unshielded twisted pair (UTP)
cable. The balun is installed at the CCTV camera and is powered by the camera power
supply. There are two (2) models; 500100 for 12VDC cameras and 500101 for 24VAC
cameras. The Active CCTV Transmitter Balun features ground loop isolation and manual
gain compensation adjustment based on cable length.
Installation
The Active CCTV Transmitter Balun is designed to be installed at the CCTV camera
only. In order to install the Active CCTV Transmitter Balun, perform the following
steps:
1. Determine the cable length between the CCTV camera and the receiver at the
head end.
2. The Active CCTV Transmitter Balun has a 4-position gain adjustment DIP
switch. The switch is factory set for a cable length of 750 ft (228m) to 1,500 ft
(457m). If the cable length is within this range, proceed to Step 6. If the cable
length is outside this range, proceed to the next step to adjust the switch setting.
3. In order to access the gain adjustment switch, slide the cover off the balun to
reveal the internal components as shown in the following figure.
