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.
root
and the default password is
summit
. 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.

FCC Statements of Conformity
FCC Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one of the following measures:
