8. Will the LEDs
on the Model 360 Satellite Modem help to confirm Rx lock on the
The Rx light on the Model 360 will
illuminate if the modem has been configured and you have obtained
Rx lock on the assigned satellite. Once Rx lock is achieved, the
Synchronization (SYN) light will illuminate, indicating the satellite
timing sequence has been accomplished with the StarBand Hub and
within 30 seconds the Connection (CON) light will illuminate, indicating
the VSAT is communicating with the StarBand Hub.
Even if you are locked on the assigned satellite,
the Rx light and the SYN light will still illuminate if:
- The modem has been
incorrectly configured (incorrect zip code or site parameters)
- The antenna feed
assembly has the incorrect transmit polarity (applies only to
However, the CON light
will not be on.
All three of these lights (Rx, SYN & CON) must be on before you
call into CVACS and a Continuous Wave (CW) is generated to obtain
co-pol and cross-pol alignment values

when Model360 has been configured and detects the Gilat OB
frequency. Modem must be configured to get Rx. This will indicate
a working receiver on the antenna and a functional connection
through the receive side of the RF cabling. If the modulator
for a given cluster outbound is operational, the VSAT will
get Rx even if the cluster is not fully functional.
when the Model 360 is synchronized with the hub, i.e. the
VSAT is receiving synchronization packets or time clock data
from the hub. SYNC will indicate that the hub is transmitting
one-way data to all VSATs in it's footprint.
when a correctly configured VSAT at the NMS (SatModem ID,
IP Address, MAC Address) has finished the downloading phase
and is ready to work. [If the MAC address is not configured
correctly the LED will come On, but the VSAT will not operate
properly and Mission Control Icon will indicate ISP Not Authorized].
Indicates functional aspects of both sides of the connection
between Hub and VSAT and all cabling throughout.
when Model360 is transmitting (burst mode).
when Model 360 detects connectivity with PC. (Note that drivers
for the USB cable do not need to be installed for this to occur).
