Connect any Ethernet device to the XPress Ethernet Bridge
RF Modems and the bridge will function in place of
an Ethernet cable. The Ethernet bridge provides a
transparent wireless point-to-point cable replacement.
This manual provides step-by-step instruction on how to setup a wireless link and test the
Ethernet Bridge’s ability to transport data over varying ranges and conditions.

Quick Setup
Hardware Setup
1. Using the power adaptors, plug in each of the XPress RF Modems to an outlet.
2. Connect an Ethernet cable from each XPress RF Modem to a network device.
3. Send Ethernet traffic through the wireless Ethernet Bridge [for trou bl eshoo ting, refer to
the following page].
Each RF Modem automatically selects the best radio channel, encrypts the Ethernet traffic and
transports the data wirelessly to its matched pair . Cross-over cables are not necessary since the
RF modems automatically sense the device (client vs. switch).

Troubleshooting
No Power LED:
Check the power connections.
No Radio Link LED:
The radio is looking for its matched partner. If both units are powered up and the Power LEDs
are active they may be too far away to create the radio connection. Try other locations that may
have a less obstructed path or try to reorient the antennas.
Yagi-type antennas get their best range when they are both oriented to point directly at each
other with the antenna elements oriented in the same plane (e.g. vertically or horizontally).
Radio Link LED on but Quality Indicator is low:
The units may be too far away to create a good radio connection. Try other locations that may
have a less obstructed path or try to reorient the antennas.
No Ethernet Link LED:
Check your network connections.
Still not working?
If practical, temporarily use an Ethernet cable to see if the network is working ov er a wired connection. If a wire does not work then the problem is with the network.
PRODUCT LIMITED WARRANTY:
This product is warranted to the original purchaser for normal use for a period of 30 days from
the date of purchase. If a defect covered under this warranty occurs, MaxStream will repair or
replace the defective part, at its option, at no cost. This warranty does not cover defects resulting from misuse or modification of the product.
Advanced Settings
Automatic Frequency Selection Mode (All DIP Switches OFF (up))
<Default Configuration> The RF modem is designed to automatically select and continuously
optimize the performance of its radio channel. The radio channel is monitored to ensure it is
providing low error rates necessary for successful radio transmission. In the event that the
error rate rises, the RF modem will autonomously change to a new channel. There are 12 nonoverlapping channels.
Australia only: In order to comply with Australian regulations, all modems intended for use in
Australia are pre-configured to operate on 6 channels and DIP Switches are disabled.
Manual Frequency Selection Mode
To restrict the operation of the RF modem to a subset of the 902-928 band, the user may activate a manual selection mode that allows the radio to automatically choose the best channel
within a grouped subset of the 12 available channels. This is enabled by the 8-position DIP
switch on the master unit. These settings allow the RF modem to operate on the optimal channel in one of three subsets: LOW 4, MID 4 or HIGH 4.
ChannelsFrequency RangeDIP Settings
LOW 4 - 1,2,3 or 4903-909 MHz2 ON / 3 OFF
MID 4 - 5,6,7 or 8911-917 MHz2 OFF / 3 ON
HIGH 4 - 9,10,11 or 12919-925 MHz2 ON / 3 ON
Or - the user may wish to select a specific channel. This can be done by setting DIP switches 58 as shown in the table below. [Turn DIP 2 Off / 3 Off]

Site Survey Mode (DIP Switch 4 is ON (down))
In this mode the RF modem can perform a site survey . With this mode activated the r adios send
and receive at 100% capacity by transceiving self-generated simulated data. The installer can
monitor the Link Quality display to assess channel quality while optimizing antennae orientation. The installer can manually select each channel to evaluate performance and identify the
best channels for operation. By identifying channels with poor performance it is possible to
identify possible interferers and use "Manual Frequency Selection Mode" to avoid portions of
the band or select a fixed operating frequency.
Important Note: Ethernet traffic does not get transported while the RF modems are in Site Survey Mode.
