PHYSICAL INTERFACES
Serial Data Interface
- The serial asynchronous interface allows connection to external serial devices. It is
shared between user data and unit’s command/status information. All commonly supported baud rates, par-
ity and bit configurations are available up to 115.2 kbps.
Power Interface
- The power interface allows connection to an unregulated DC power source. The DC power
source (third-party or user supplied) must provide DC power of 4.0V±5% DC.
The standalone unit’s RF interface is a 50-ohm impedance matched standard MMCX connector as required by
regulation.
Antennas
- Antenna type depends on the site requirements, and may be directional or omni-directional.
Note:
To support 8 miles distance range between Base sta-
tion and SS unit, an antenna mast should elevate the base an-
tenna a minimum of 20 feet above the average level of the ter-
rain.
