Can also be used to transmit low-voltage (12~24) AC/DC. Fig. 5
Note 1: Output depends on adapter used. The transmitter uses 40mA. So a 12VDC, 500mA adapter gives 12VDC, 460mA through
this output, or a 24VDC, 500mA adapter gives 24VDC, 460mA through this output.

MOUNTING AND DAISY-CHAINING MULTIPLE RECEIVERS (optional) (fig. 4):
The optional EVT-xxxx 1U balun mounting plate allows up to eight EVT-RB1-4T2Q receivers to be mounted on
a standard 19-inch rack along with other video equipment for a safe and secure installation.
The receivers can be daisy-chained together for easier mounting of multiple units and to reduce the number
of power supplies, using the included patch cords with a 4-pin connector on each end.
For a clean installation, the receivers can be interlocked with each other.

INSTALLATION OF MULTIPLE CAMERAS
Standard Cat 5e UTP cable includes four pairs of colored wires. Up to four CCTV cameras can be connected per
single run of Cat 5e UTP cable without interfering with each other under normal conditions.
However, for installations where multiple cameras cannot be run over the same cable, separate cables must
be run between the cameras and the remote devices.
OTHER CABLE TYPES
The active video baluns, when used with Cat 5e UTP cable, offer the performance characteristics mentioned in
this manual. Other types of twisted cable can be used as well. However, the performance characteristics vary
from cable to cable, and so care must be taken when using other types of cable. Specifically, the maximum
distance between the camera and the remote device may decrease significantly with lower grades of cable.
Step 3:
Add jumper.
