Default is
SHORTED
. The Locked/Unlocked logic state can be reversed by including SYSTEM TYPE 0128.
Shorted provides a pull-up DC Voltage input (determined by JP5 setting) into the ACU when the
modem supplies a continuity output. This hardware connection is also routed to the Console and
OBM RJ45 ports.
Open provides a DC Voltage directly from the modem into the ACU when the modem supplies a DC
Voltage output. This hardware connection is also routed to the Console and OBM RJ45 ports.
JP5
Voltage Output Select - Select 12VDC or 24VDC.
Default is 12VDC
.
JP6
GPS NMEA Output Select -
Default is SHORTED
.
Shorted provides GPS latitude & longitude, in alternating GGA & GLL formatted messages, to be
outputted on the Terminal Mounting Strip NMEA output terminals. This hardware connection is also
routed to the Console and OBM RJ45 ports.
Open disconnects the GPS output from the Terminal Mounting Strip NMEA output terminals.
3.7.7.2. J1 “Modem Console Port” connector
FCC compliance connection to an iDirect Satellite Modem can be made very easily by connecting a
Straight Serial RJ-45 cable from the J1 “Modem Console Port” connector on the Terminal Mounting
Strip to the Console port on the iDirect Modem. Your modem must be set
If your modem is Open AMIP compatible and you wish to use it in an Open AMIP configuration you
will use an Ethernet patch or cross-over cable as is appropriate to connect to your LAN.
Refer to the Setup – Modem Connections, Setup and Test chapter for more information.
3.7.7.3. J2 “OBM Port”
The Out of Band Management port is used to connect the ACU to the out of band management
device, through the Terminal Mounting Strip. This port is also a straight Serial RJ-45 port.
