1.6. Dual Antenna Arbitrator
The Dual Antenna Arbitrator panel can pass LNB voltages (and handle 250-400 ma of current) and the RXIF signals on
the RX connections. TXIF, Reference and BUC supply voltage can be passed through this arbitrator panel to the
antenna, but it is not recommended that BUC power be supplied through the dual channel rotary joint of the antenna
(a BUC power supply is provided on all Series 09 Antenna Pedestals).
The blockage (SW2) output, GPS output and Modem lock input from the two terminal mounting strips (antenna “A”
and antenna “B”) are wired through the arbitrator panel to the satellite modem. When antenna “A” is blocked, the
arbitrator PCB will toggle the coax switches so that antenna “B” provides signal to the BDE distribution (multi-switch or
modem). When antenna “A” is no longer blocked the arbitrator will do nothing (because it is a latch circuit). When
antenna “B” is blocked the panel will switch so that antenna “A” is again providing signal the BDE distribution.
To provide a seamless switching transition, refer to the arbitrator installation instructions to balance the TX & RX signal
levels between the two antennas.
1.7. Open Antenna-Modem Interface Protocol (OpenAMIP™) Specification:
1.7.1.
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 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
Overview:
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
