The Ethernet RJ45 connector on the end of the module incorporates two indication LEDs. The LINK LED which comes on
to indicate a connection on the Ethernet port, and it will blink OFF briefly when activity is detected, similar to the LAN Led
on the front panel. The 100MB LED indicates that the LAN connection is at 100 MBit/Sec. The 100MB LED will be off for
10MB/Sec connection.
Other conditions indicating a fault are described in CHAPTER 4 - DIAGNOSTICS.
Radio Operating Parameters 3.1
Frequency Bands
The radios will operate within the range 360-512MHz; however the full range is broken into different frequency bands and
the radios will be set to one of these frequency bands. Care must be taken when ordering to select the correct band as
the frequency cannot be configured outside of its band.
The Frequency of the radio is configurable by the user within a Frequency band of the radio; the following bands are
available.
370
360 380 MHz
390
380 400 MHz
410
400 420 MHz

The modems are capable of being configured in the frequency range of 380MHz 512MHz however the modems are
factory tuned for a particular 20MHz frequency band as shown above.
