OpenAMIP setup for iDirect iNFINITI & Evolution
C-6
Appendix C: VMU settings
98-150471-A02
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.

Note
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.
