APTUS
Use Mediator: enables use of the Intellian Dual VSAT Mediator.
Use Mediator must be set to “NO” if there is no MEDIATOR con-
nected to the ACU. Improper setting of this parameter will cause
your ACU’s modem interface to work incorrectly
Select Modem: selects your modem type for loading pre-congu-
ration settings. If the ABS (auto beam switching) function is in use,
select either IDIRECT-AMIP or COMTECH-ROSS depending on
which type of modem is used.
Modem Port: selects the data communications port (RS232/ 422/
Ethernet) to interface with the modem.
Modem Protocol: selects a proper communications protocol on
the ACU to interface with the modem (I/O Console/ Open AMIP/
Serial GPS).
GPS Out Sentence: selects GPS out sentence type (GPGLL/ GP-
GGA/ Simple GPGGA).
Use TX Mute: selects whether or not to use the “TX Mute” func-
tion from the satellite modem. A transmit inhibit output from the
ACU will disable/ mute the modem transmit via a voltage change
whenever the antenna is blocked, searching, or is miss-pointed 0.5
degrees from the peak satellite position.
Use Modem Lock: selects whether or not to use the external lock
signal from the modem.
TX Mute: TX Mute is a transmit inhibit output from the ACU to dis-
able /mute the modem transmit through a 5 V (HIGH) or 0 V (LOW)
current whenever the antenna is blocked, searching, or is miss-
pointed 0.5 degrees from peak satellite position. TX Mute will only
be activated when modem protocol is set as I/O console.
Modem Lock: is the modem lock output from the modem. It pro-
vides a logic input through a 5V (HIGH) or 0 V (LOW) current to the
ACU to identify when the system is on the correct satellite.
• Modem: sets the interface between the ACU and the Intellian Dual VSAT
Mediator or the satellite modem.
