Dear all,
How can I communicate seatel antenna (marine) with 3100 modem? 3100 - mobile (input NMEA). Rx lock. Tx - off. NMEA from controller via NMEA port to consol 3100 modem.

From the above this looks like a GPS problem, if no GPS is present no TX will go on unless you have made this a static site

Other problems can be blockage zones on the antenna (also possible bad wiring causing a mute into the idirect modem)

is there GPS on this system?

iDS Release 7.0.0.x to 7.0.1.2-- TX is muted on the Mobile Remote if the look angle(elevation) for the antenna is below 10 degrees.
Details:
By default, for all Mobile Remotes with GPS input, if the antenna look angle ( elevation) is below 10 Degrees , the GPS input is ignored and TX is muted. On the console you will see a message [ MUTED] . This will prevent the remote from acquiring into the network.
Resolution:
In a future release this default behavior will be changed to not perform this check.
Workaround:
Currently, the workaround is to apply a custom key on the remote side configuration of the remote, to disable this check. The Custom key is as follows: [SATELLITE] min_look_angle = 0.0
I have look anagle = 10 Degrees .
