1.5. Open Antenna-Modem Interface Protocol (OpenAMIP™) Specification:

1.5.1.

OpenAMIP

, an ASCII message based protocol invented and Trademarked by iDirect is a specification for

the interchange of information between an antenna controller and a satellite modem. This protocol allows

the satellite modem to command the MXP (via TCP port 2002) to seek a particular satellite as well as

allowing exchange of information necessary to permit the modem to initiate and maintain communication

via the antenna and the satellite. In general, OpenAMIP

is not intended for any purpose except to permit a

modem and the MXP to perform synchronized automatic beam switching when using an iDirect Network. It

a status logging system or a diagnostic system. In addition, OpenAMIP

is intended for a typical

installation whereby a specific satellite modem and Antenna system are properly configured to work

together. The protocol does not make specific provisions for auto-discovery or parameter negotiation. It is

still the responsibility of the installer to ensure that the parameters of both the satellite modem (proper

option files) and the MXP/PCU (setup parameters) are actually compatible for the intended satellite(s).
