Ipoint Operation Monitoring
The Ipoint Antenna control system is designed to be very simple to operate and is expected to be fully
automatic in acquiring the required satellite signals.
However the system does not provide very much user feedback if the satellite acquisition operation
does not complete.
This document is intended to provide method to gather information on the progress of the satellite
acquisition.
1 Serial Communication
To communicate with the Ipoint system a PC with a serial port is required. The information below
described the use of hyper-terminal as a "terminal emulator", but any similar program could be used
instead.
One unusual point about the serial interface is that the UIU front panel will keep trying to take control
of the interface. When this happens you may see “garbage characters” generated. To reduce the effects
of this type an extra “carrige return” evry 10 seconds or so, The normal serial parameters are
19200,n,8,1 but mobile systems which connect the UIU to a DVBRCS modem are typically set to
4800,n,8,1.
The Baud rate can be changed via the UIU front panel.
Press the buttons as follows:-
Down arrow *6 Display Shows "User Setup"
Enter Display Shows "Final Pol"
down arrow *4 Display Shows "GPS Output"
Enter Display Shows "4800"
Enter. Display Show "19200".
Clear. Return to main menu.
This baud rate change is not stored. The next time the system is power cycled the baud rate will
revert to normal operation.
The connection is taken from the RJ-11 front panel connector on the Ipoint User Interface Unit.
A cable can be supplied but connection details are shown below.
RJ-11 TO 9-PIN D-Type Socket ADAPTER CABLE
To connect a PC to the UIU Front Panel M&C connector use this adapter cable. Adapter
cables must be individually wired. Follow the pinout listed in table below.
The diagram shows the pinout for the RJ-11 connector, looking into the socket on the
panel. This is a 6 pin version of the RJ-11 connector, sometimes known as an RJ-12
