PVE400 USER’S GUIDE
2.3 Using other video/audio source
PVE400 can accept any standard video source. The optional
PVE-AV split cable has a standard RCA female connector
(Yellow) for video input. PVE400 can provide 12V/200mA
power for an external camera using a standard power jack. This
power source is protected by resettable fuse with 400mA limit, to
secure PVE400 from accidental shortage.
The standard electret microphone can be connected to the audio
jack. PVE400 will provide 1.1V DC bias for the microphone on
the same connector.
See also the table in section
for the connector pin out, if the
custom cable is needed.
2.4 Powering up
Press and hold the power button (Figure 2 -1) until the
green LED
is on (Figure 2 - 5). The unit will be ready for
operation as soon as the
status LED
is lighted (Figure 2 - 6). To turn off, press and hold the power button again,
until
all
LEDs
are off. When the external power adapter is attached, the unit will turn on immediately. The
power button works only for battery. Alternatively the unit can be powered via AUX connector (see the table in
section
). This is useful if the unit operates with an external power source, for example inside a car, or while
stationary mounted.
Warning
:
Do not remove the battery, even if the unit is always working with the external power source.
2.5 Battery charging
The battery can be charged using an external charger (optionally supplied p/n PVE-ECx) or internally using
bundled AC /12VDC power adapter (PVE-PS with AUX adapter). The charging time of a
fully discharged
battery is about 5 hours. During the charging process PVE400M will operate normally. On the bottom cap two
additional LEDs will show status. If power source comes from AUX connector,
External Power LED
11) will be solid green,
Charger Status LED
(Figure 2 – 10) will be solid
red
if battery is charging and change to
solid
green(amber)
if battery is fully charged.
When AC/DC adapter is connected, the battery will always be in the charging state, but the internal circuit will
prevent the unit from overcharging.
When the battery is internally charged, turn on the unit by pressing the battery power button first, then attach
DC-AUX plug. This will insure calibration process of the battery monitor. When the unit is fully charged, the
capacity monitor will work with 1% accuracy in this case.
It is also possible to charge from a car battery using an optional cable PVE-VPS (cigarette lighter plug to AUX),
in the same way as using PVE-PS.
Aluminum case of PVE400M is electrically connected with internal ground signal (negative). The external
power source must be positive. PVE400M has a built-in protection from reverse polarity of an external power
source.
Note:
AC/DC adapter is designed to use only for indoor environment.
