Transceiver Installation Overview
To successfully install a transceiver, follow the basic steps listed below.
1. Determine the best location for the transceiver.
2. Install the ground rod.
3. Install the NEMA 4 enclosure
4. Mount the transceiver and power supply into the enclosure.
5. Route data cables to the end device.
6. Connect power and configure the transceiver.
7. Install the antenna.
8. Connect a surge suppressor between the external antenna cable and interior cable connected to
the transceiver's RF connector..
9. Waterproof all external connections.
Choosing a Location for the Transceiver
Placement of the FreeWave transceiver is likely to have a significant impact on its performance. The key to
the overall robustness of the RF link is the height of the antenna. When using an external antenna, placement
of that antenna is critical to a solid data link. Other antennas in close proximity are a potential source of
interference; use the Radio Statistics to help identify potential problems. In general, FreeWave units with a
higher antenna placement will have a better communications link. In practice, the transceiver should be
placed away from computers, telephones, answering machines, and other similar devices. FreeWave
Technologies, Inc. offers directional and Omni directional antennas with cable lengths ranging from 3 to
200feet.
The Show Radio Statistics page is found in option 4 in the main terminal menu or in the Diagnostic information
in Tool Suite. An adjustment as little as 2 feet in antenna placement may resolve some noise issues.
Installing the NEMA Enclosure
The NEMA enclosure selected for the installation site should be a NEMA-4 rated enclosure. NEMA 4
enclosures are gasketed and the door is clamped for maximum sealing. NEMA 4 enclosures are available in
sizes from small wall mounts to two-door floor mount models. The selection depends on the requirements of
the particular installation and the amount of equipment to be placed inside.
Follow the installation instructions provided with the NEMA enclosure, ensuring that no holes are drilled on the
top of the enclosure. Holes on the top of the enclosure can allow moisture and other elements into the
enclosure. Ensure holes on the sides and bottom are waterproofed.
Mounting the Transceiver in the NEMA Enclosure
FreeWave transceivers have several mounting options including metal plates, din rail clips, and brackets.
When mounting any transceiver, ensure that it is mounted to a flat, stable surface using the mounting bracket
or the mounting holes in the corners of board-level transceivers.
