Introduction
The following units are covered in this manual:
Boxed video transmitter BVT-230.
Boxed video receiver BVR-230-1GV/3.
Boxed video repeater BVX-230-1GV/3.
All three units are fully compatible with other Ernitec twisted pair video equipment.
However, the specified transmission distance, and adjustments, assumes the use of
Series 230 equipment only.
Throughout theses instructions, reference is made to the drawings which can be found in
the back of these instructions.
General
The Series 230 Twisted Pair Video Transmission equipment, is designed for use with
standard CAT5e twisted pair cable. It can also be used with standard 120 ohm twisted pair
cable, suited for video transmission. Types like the Belden 1872A or 1700A, can also be
used.
On the receivers, and repeater, the twisted pair input is galvanically separated to avoid
earth loop problems (hum bars).
All boxed types are housed in an IP65 rated enclosure.
The Boxed Series 230 types are mains supplied - 230VAC, but can also be ordered in
115VAC versions.
Coax and twisted pair cables, can be connected/disconnected with power on.
Box Installation
Choose a plane surface to prevent the box from being twisted and thereby becoming
leaky when mounted. When mounted outdoor the box should be installed with the cable
glands downwards.
Screws and wall plugs are supplied in the mounting kit. Drilling dimensions are shown in
the back of this manual.

Mains Installation
Terminals marked with hazardous live symbol requires installation by an instructed
person.
The BVT/R/X-230 must be used with a 3-wire mains connection (2W+PE @ min.
0,75mm2).
If permanently connected to mains, a readily accessible disconnect device shall be
incorporated in the building installation wiring.
If pluggable connection to mains, the socket-outlet shall be installed near the equipment
and shall be easily accessible.
In order to fulfil the safety standard (EN60950), the mains cable must be routed via the
provided cable clip inside the Series 230 box. The figure below shows how the mains
cable should be routed.

WARNING: Make sure the equipment is earthed; otherwise the over
voltage protection will not work! Although both the transmitter and the
receiver are earthed no hum bar problems will occur due to the galvanic
separation of the video signal in the receiver.
Cable Connections
Please refer to the drawings in the back, for details on cable connections.
At the receiver end, do not in any way connect the twisted pair shield. If the shield is
connected to the receiver, the galvanic separation will not work!
The shield should be connected at the transmitter end only.
