Protocol and interfaces
Introduction
The following sections describe the protocol and interface between the SAILOR 900 VSAT
High Power ACU and an iDirect OpenAMIP VSAT modem. OpenAMIP operation is normally
used by service providers offering global VSAT service as 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 (VMU). 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.
Important
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.
