Laird’s RAMP Bridge provides a simple, high-performance wireless Ethernet cable

replacement system that eliminates the frustration, cost, and complication of its

competitors, all contained in a small, durable, form factor. Say goodbye to
enormous outdoor antennas that rely on directional precision and complicated
alignment. Laird’s RAMP Bridge makes it easier than ever to achieve industrial-

strength long-range Ethernet cable replacement in any environment.

Safety

Important Notice: Please read all instructions carefully before

attempting to install and use this product.

RAMP Bridge and all associated equipment should be installed in
accordance with applicable local and national electric code
guidelines to ensure safe operation.

Precaution

For best results, make sure the connector is clean and free from
any metal flakes/dirt. Tighten the connector using a torque
wrench. Also, do not remove the dust cap from connectors when
not in used.

Placement

For best results, orientate RAMP Bridge vertically as shown
below. The top portion of the unit contains an omni-directional
antenna; for best results, the upper portion should be located in
free space with no obstructions in the antennas near-field.

Device Setup and Connections

The RAMP Bridge may be powered by either a network switch that supplies 48VDC (802.3af compliant) Power Over Ethernet
(POE) or by using any 802.3af compliant POE injector. If using the network switch with POE, use a standard CAT 5 or CAT 6
cable to connect the device to the switch. If using an external POE injector, set up according to the manufacturer’s
recommended connections. A few seconds after power is first applied to the Ramp Bridge device, the LEDs light up in a
pattern from top to bottom. Once finished, the device is ready to be used or configured.

Configuration

RAMP Bridge units are configured via any standard web browser. Enter the IP address of the RAMP Bridge unit into a browser
(default IP is 192.168.3.1) and log in. The default login is
that you immediately change the admin credentials. To do this, click Change Admin Credentials in the upper right side of the
screen.

RAMP Bridge units are configured as either a server or a client. Each network should have only one server and can have
between one and five clients. By default, units are configured as a client. To set up a network, first configure the server using
the web browser as shown below.

For the server, the only configuration options:

 Network Name – Unique name of the network shared among

the server and client.

 Passphrase – Security key for clients to authenticate

communication to server. This is used for over the air
communication; it is not the same key as the device login
password. The server and client(s) must have the same
passphrase.

 Channel Number – The channel for radio communication.
 IP Address – The IP address used to connect to the device for

configuration.

and the default password is

. We highly recommend

Then configure each client in the network as shown in the image to
the right.

For the client, the following are the only configuration options:

 Network Name – Unique name of the network shared among

the server and client.

 Passphrase – Security key for clients to authenticate

communication to server. This is used for over the air
communication; it is not the same key as the device’s login
password. The server and client(s) must have the same
passphrase.

 IP Address – The IP address used to connect to the device for

configuration.

Once all configurations are saved, the units can be used in a point-to-point or point-to-multipoint bridging operation.
