©e2v technologies (uk) limited 2010 107553 09 Aug 2010 DAS762156AA (UK) Version 11, page 17
INSTALLATION
The EPVA requires a DC power source of between 10 and 30 V DC. A vehicle accessory plug is
provided (cigarette lighter), or this may be removed for direct connections to be made. Do not
connect directly to a mains voltage supply. The supply should be capable of supplying up to 10 W
(1 A at 10 V or 300 mA at 30 V). Reverse polarity protection is provided in the EPVA. The circuit
protection against reverse polarity and vehicle transients is inside the junction box and direct
connection from the cable or into the Battery Replacement Unit should not be attempted.
Note the limitation of use on page 2. The EPVA must not be used as a driver vision device for
example.
Analogue video will only be available when coupled to a suitably equipped camera, it is not
present as standard on all cameras.
Models P7030, P7030-LITE, P7009, P7130, P7225/D and P7250/D do not have analogue video
output capability.
Model P7030-LITE does not have any video output facility.
If in doubt please contact your distributor or e2v for advice on use with the cameras that you own.
Mount a camera as required. A standard tripod thread is fitted in the base of an Argus
®
4 for this
purpose. There is also a mounting bracket accessory available as P7030MB.
Connection to the camera is by fitting the Battery Replacement Unit in place of the standard
battery on the camera. Use the 1.7 m lead to place the junction box in a more convenient or
protected location.
The junction box network connector is a Woodhead RJ-Lnxx rugged industrial network socket
allowing the use of industrial or standard network leads. The socket has been wired with a network
crossover inside the unit. A standard network lead will allow connection directly to a computer,
while most routers will automatically sense polarity and still connect correctly. Full contact area
sealing is only maintained with the use of the matching RJ-Lnxx plug.
Where the EPVA is used solely to power a camera or for analogue output, the sealing cap should
be secured in place on the network socket.
The analogue video output is direct from the Battery Replacement Unit and should use a 75 Ω
cable suitable for the location (e.g. high temperature or low smoke).
A computer is required to receive digital video and the configuration options for this are covered in
section 9. It is recommended that a computer with a second network device is used for connection
to cameras, either as a point-to-point or small router based network, separate to other corporate
and internet connectivity.
Analogue video is in NTSC 60 Hz format and can be displayed on a standard video monitor or
through most modern TV sets by using video inputs. The connector on a television or video
recorder is usually an RCA phono socket and coloured yellow and labelled ‘AV in’ or similar. The
camera does not connect directly to the antenna socket.
Both the Junction Box and Battery Replacement Unit are sealed. There are no user serviceable
parts inside.
The default setting is for the camera not to send output video when turned on in order to conserve
power when in normal battery powered use. It may be found more convenient to set the camera
always to turn on with output video sending through setting this mode with the customer software.
With the automatic switch on this will give a fully automatic camera feed from just switching the
power to the EPVA.
