- Use Mediator: enable the usage of Mediator if the antenna is
connected to the Intellian Dual VSAT Mediator. Use Mediator
must be set to “NO” if there is no MEDIATOR connected to the
ACU. Improper setting of this parameter will cause your ACU’s
modem interface to work incorrectly.
- Select Modem: is to select a proper data communication port
and protocol on the ACU to interface with the satellite modem.
The settings related to the modem interface will be set auto-
matically once the modem type is selected (USER SETTING,
IDIRECT-I/O, IDREICT-AMIP, COMTECH-I/O, COMTECH-
ROSS, HUGHES, SATLINK-SERIAL, SATLINK-VACP, ELEK-
TRIKOM-AMIP, GILAT-SE-II, IPSTAR-SOTM.
However, it is required to set the related settings separately if
USER SETTING is selected.
- Modem Port: is to select a proper data communication port on the
ACU to interface with the satellite modem (RS232/422/ Ethernet).
- Modem Protocol: is to select a proper communication protocol
on the ACU to interface with the modem (I/O Console,
OpenAMIP, Serial GPS, ROSS, VACP, ELEKTRIKOM AMIP, GILAT).
- GPS Out Sentence: is to select the GPS out sentence type (GP-
GLL/GPGGA/SIMPLE GPGGA)
- USE TX Mute: is to select whether or not to use TX mute
function from the satellite modem.
- USE Modem Lock: is to select whether or not to use external
lock signal from the satellite modem.
- TX Mute: is a transmit inhibit output from the ACU to disable/
mute the modem transmit through a 5V (High) or 0V(LOW) cur-
rent whenever the antenna is blocked, searching, or is mispoint-
ed 0.5° from peak satellite position.
- Modem Lock: is the modem lock output from the modem which
provides a logic input through a 5V (High) or 0V(LOW) current to
the ACU to identify when it is on the correct satellite.
- Use Modem Lock Verify: With this option on, the antenna will
change to search mode if there is no modem lock signal in NBD
tracking mode, reducing overall time spent for satellite search.
With this option off, the antenna will continue to stay in tracking
mode.
Note:
TX Mute and Modem Lock items will only be activated
when the modem protocol is set as I/O Console.
