Notes for Figure 4
1. This example of a host system motherboard footprint is shown for illustrative purposes only. The host
system may require a different PCB layout or mechanical arrangement.
2. The 9602/9602N is designed to be incorporated within a host system. As such, the antenna or cable
distribution system that feeds the host system should be terminated in a robust RF connector that is
suitable for the end-application.
3. Safety isolation requirements for external antennas or cable distribution systems should also be taken
into consideration when designing the motherboard. A suitably safe design for the RF connections
should be incorporated into the host system motherboard, ideally using a chassis-bonded ground
connection to the antenna cable shield.
4. The surface below the modem should be a conductive ground plane such that the modem bonds to
the motherboard ground system thus reducing the possibility of radiated emissions. This also requires
that the mounting screws get properly tightened to 7 pound-inches of torque.
5. The modem is to be installed in a “service access only” area not accessible by untrained personnel.
Warning- Although the modem dissipates very little power, its use in ambient temperatures
in excess of 60 deg C will make the caseworks considerably hot.
