Getting started
Power Supply
The BRD-355 requires a DC power source in the voltage range of 10 to 60 VDC. The
unit is designed to self protect from permanent damage if the voltage exceeds 60 VDC
or if reverse polarity is applied. The router may need to be returned for service if this
occurs. The router can also be damaged if there is any potential difference between the
chassis-ground, RS-232 signal ground or power (–) input. Before connecting any wiring,
ensure all components are earthed to a common ground point. An external isolator will
be required if a positive earth power supply is used.
Ethernet
The Ethernet ports are on the front of the unit and are marked LAN 1 and LAN 2, each
port has a LED indicating the connection speed and a LED indicating activity as shown in
figure below. Both ports are capable of auto-negotiation, meaning cross-over cables are
not required. The Ethernet ports are switched, allowing more than one Ethernet device
to be connected to the unit at one time.
