DAC-2202 Antenna Control Unit Basic Configuration Information
3-1
3. Basic Configuration Information
This section provides you with some additional information about the satellites you will be using, some basics of your satellite
antenna system and other equipment within your system configuration. For more information about you specific antenna,
refer to its manual.
3.1. Open Antenna-Modem Interface Protocol (OpenAMIP™) Specification:
3.1.1. Overview:
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 ACU (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 ACU to perform synchronized automatic beam switching. It is
NOT a status logging system or a
diagnostic system. In addition, OpenAMIP is intend 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 assure
the parameters of both the satellite modem (proper option files) and the ACU/PCU (setup parameters) are
actually compatible for the intended satellite(s).
