4.10. Monitor And Control Connections

J2 NMEA
- The NMEA Port allows 2 simultaneous NMEA-0183 input connections on the same DB9
connector, defined as NMEA A and NMEA B. Both ports have selectable baud rates independent of each
other. In addition, NMEA A Tx- Line (J2- Pin 3) outputs a pseudo NMEA string (GGA format) which can be
connected to an external device, such as a satellite modem, to provide Latitude and Longitude position.
o
NOTE
: The factory default for NMEA heading input is xxHDT, if the gyro input into the ACU is providing
heading information in any other format, you must use the internal webpage to configure the NMEA
Heading ID parameter for proper operation. Example if you have a heading input providing xxHDG
heading strings, you would set up the NMEA Heading ID parameter to
HDG . Refer to the
“ Communications Port Settings ” information in the Maintenance section of this manual.

J3 M&C - The Monitor and Control port allows external control from a PC using a communications program
such as Sea Tel ProgTerm or DacRemP via a straight 9 wire serial cable. This Port is used in conjunction with a
diagnostic software connection to configure all communications settings, and/or for an
Authorized Sea Tel
Dealer to perform software uploads to the PCU, ACU Main PCB, and DVB Receiver.

Ethernet - The Ethernet Port allows use of a LAN connection to login into the ACUs internal webpage’s to
view or change system parameters using a web browser such as Internet Explorer or Mozilla Firefox and a
standard CAT5 Ethernet patch cable. This 10BaseT Ethernet Port has a configurable static IP address with 2
TCP/IP connections for diagnostic software connections and a UPD Port for an
Authorized Sea Tel Dealer
to perform a software upload to the Comm IF Module. For operating a ABS VSAT system, this Ethernet port
must be connected via a CAT5 patch cable to an available LAN port of an OpenAMIP™ compatible satellite
modem ( i.e. an iDirect 5000 Series satellite modem)
4.11. Install Other BDE Equipment
Install and connect the other below decks equipment as required.
4.12. Final Checks
4.12.1. Visual/Electrical inspection
Do a visual inspection of your work to assure that everything is connected properly and all cables/wires are
secured.
4.13. Power-Up
Verify that all shipping straps and restrains have been removed prior to energizing the antenna.
When all equipment has been installed, turn ACU Power ON. If the ACU does not provide power to the antenna, turn
antenna power ON. The ACU will initially display “SEA TEL – MASTER and DAC-2202 VER 6.xx”. If the Antenna is
energized, approx. 10 seconds later the display will change to “SEA TEL – REMOTE and INITIALIZING”. After
initialization, the bottom line of the remote display will display the antenna model number and the software version
from the PCU.
Energize and check the other Below Decks Equipment to verify that all the equipment is operating. You will need to
assure that the ACU is setup correctly and that the antenna acquires the correct satellite before you will be able to
completely check all the below decks equipment for proper operation.
4.14. Setup
If your system includes the Touch Screen Controller, refer to the Setup chapter in the TSC-10 manual to setup the
ACU. If not, refer to the Setup instructions in the next section of this manual to assure that the ACU settings and
parameters are set correctly for your desired satellite.
