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.
3.7.7.4. TS1 Control Interface
Connections.
AGC & GND - External AGC, or Modem
Lock, input.
•
External AGC input to the DAC-
2202 must be 0 to 15 Volts DC
analog signal, positive going
voltage proportional to satellite
signal input level and must be
real-time in its response to
antenna pointing.
•
External Modem Lock from a
satellite modem is used as a
positive ID that the antenna is on
the desired satellite.
This input
is NOT used for Tracking
purposes
, it is only used for
satellite identification to acquire
the correct satellite during
search. To enable the external
modem input you must include a
2 in the SYSTEM TYPE
parameter (If your system type is
presently 76 or 77, then change it
to 78 or 79) and
NID MUST be
set to 0000 .
• Connections - The modem lock
signal connects to EXT AGC and
