OpenAMIP setup for iDirect iNFINITI & Evolution
C-6
The signal strength from the modem is measured on RS-232 pin 9. It is a DC voltage in
the range of 0 - 5 VDC.
The signal strength displayed web interface on the Dashboard as 0 – 500. The minimum
value for an Internet connection is 250 - 260.
C.2.2 Sample options file
This section presents a portion of a sample options file with OpenAMIP parameters that
must be defined for FV-110. Each parameter is in bold and commented.

Table C-3: Messages sent from the ACU to the VSAT modem (examples)
The iDirect modems only sends the satellite information once when booting.
If the ACU has not received the information for some reason, the system
cannot point. In that case the modem will automatically boot after 5 minutes
and send the satellite information again.
Ranges for signal strength
VDC Antenna status
0-2.5 RF energy is detected, but from the wrong satellite.
2.6-5.0 Carrier lock, correct satellite.
