Evolution
C.1.1 Protocol and interfaces
Introduction
The following sections describe the protocol and interface between the ACU and an iDirect
OpenAMIP VSAT modem. OpenAMIP operation is normally used by service providers
offering global VSAT service because the protocol supports roaming between satellites
(Automatic Beam Switching).
OpenAMIP, an ASCII message based protocol invented and Trademarked by iDirect is a
specification for the interchange of information between an antenna controller (ACU) and
a VSAT modem. This protocol allows the VSAT modem to command the ACU to search and
lock to a particular satellite as well as allowing exchange of information necessary to permit
the VSAT 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.
Connections
Connect the ACU and iDirect modem with the following cables:
• Ethernet cable for TCP/IP data communication
• RS-232 console cable for signal strength indication (part number: 407090A-020)
• 75 Ohm RF cables F-F connectors for rx and tx frequencies.
It is important to connect this cable to achieve satisfactory acquisition of
the satellite. This is due to missing information in the iDirect OpenAMIP
software before version 3.1.1.2/13.0.1.2. RSSI information on the
dashboard will only be available with this cable connected.
