Industrial 8-Port Gigabit Switch
User Manual – DN-651108
Introduction
This industrial 8 port Ethernet Switch is designed especially for IP
surveillance, traffic monitoring and for a broad range of applications. It
can be used as a stand-alone device for buses, trucks, and other vehicles
for surveillance purposes. This unit is suitable for heavy usage
environments or central control areas where a reliable device is critical.
It has been rigorously tested for your security, transportation and telco
application.

Power connection
This unit comes with a 6 pin terminal block. It can be operated from
12-56VDC power source. Always make sure your input voltage is within
this supported voltage range for each model.
WARNING – Any exceeded input voltage will not make this unit
function and may damage this unit.
To connect power: Follow the printed polarity for PW1+, PW1-, PW2+,
PW2-, and ground. Connect positive wires to PW1+ and/or PW2+,
connect negative wires to PW1- and/or PW2-, and connect the neutral
wire to the ground screw as shown.
Relay: This unit includes an additional 24V@1A relay circuit for special
purpose. When 2 powers are connected, the relay is in OPEN mode. If
only one of the power sources is connected, the relay changes to SHORT
mode. This relay will only work with PW1 and PW2. It is independent
from PW3.
Power connecting procedure:
STEP 1 – Pull out 6 pin terminal block.
STEP 2 – Connect wire to PW1+, PW1-, PW2+, PW2-, and the
Neutral wire to the ground screw.
STEP 3 – Plug connected 6 pin terminal blocks back into place.

WARNING -- Always SHUT OFF power source to connect power wire.
WARNING -- Always ground the power source to maintain a clean
power input. Cheaply made power supplies create too much noise and
will cause the power input to fluctuate when connected to this unit. To
avoid this, always ground the power source to maintain a clean power
input.
