2. Quick Start Guide
Welcome to the Quick Start Guide for the 9256 radio modem. This guide provides step-by-step instructions,
with simple explanations to get you up-and-running. For further information, please refer to the other
sections in the user 9256 user manual.
2.1 Mounting and Environmental Considerations
The 9256 can be mounted to a panel or tray by means of screws or bolts, using the hole slots provided. The
9256 OEM will require 10mm stand-offs to prevent components on the PCB from touching the panel and
short-circuiting. For more information on the dimensions of the 9256, please consult the technical
specifications section in Appendix A of the 9256 user manual.
The radio should be mounted in a clean and dry location, protected from water, excessive dust, corrosive
fumes, extremes of temperature and direct sunlight.
2.2 Connecting Antennas
The RF antenna system should be installed in accordance with the manufacturers notes. The RF connector
used on the 9256 radio is an BNC female connector. Always use good quality low loss feeder cable, selected
according to the length of the cable run. Ensure all external connections are waterproofed using
amalgamating tape. Preset directional antennas in the required direction using a compass, GPS, or visual
alignment and ensure correct polarisation (vertical or horizontal).
