Function Description
Channel Search The Wireless Matrix Modem is tuning to various frequencies
and searching for a Data Hub (DH) signal (there is more than
one signal). This will occur under the following conditions:
- the Initial DH Frequency is incorrect or was never entered.
You may enter this value from the Installation window.
- the DH signal is not present due to a blockage (e.g. truck,
building, trees, mountain, etc.), or the system provider took
the DH signal off air.
- the antenna is out of alignment or damaged.
Pilot Search When the channel search has failed to find a valid Data Hub
(DH) frequency the Wireless Matrix Modem will search for pilot
frequencies. Tuning to a pilot allows the Wireless Matrix
Modem to correct for any frequency drift and restart the
channel search.
Tx Disabled The window is being modified and may receive data; however,
it cannot send any data.
SASK Invalid The Seed Access Security Key (SASK) parameter is incorrect.
Check the SASK entered. Contact the Value Added Reseller
(VAR) that provided the Wireless Matrix Modem to have it
fixed.
MUI Invalid The Mobile Data Services (MDS) User Identification (MUI)
parameter is incorrect. Check the MUI entered. Contact the
VAR that provided the Wireless Matrix Modem to have it fixed.
Fade The Wireless Matrix Modem is receiving the current Data Hub
(DH) channel with a Signal to Noise Ratio (SNR) that is below
an acceptable level. This may occur under the following
circumstances:
- the DH signal is not present due to a blockage (e.g. truck,
mountain, etc.), or the DH signal was taken off air by the
system provider.
- the Wireless Matrix Modem is crossing to a new beam.
- the antenna is out of alignment or damaged.
