9711 C & Ku-Band TXRX Introduction
1-3
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 pass 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.
The blockage (SW2) output, GPS output and modem lock input from the two MXPs (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 and RX
signal levels between the two antennas.
1.7. Open Antenna-Modem Interface Protocol (OpenAMIP™) Specification:
1.7.1. Overview:
OpenAMIP
TM
, 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
TM
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
TM
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 ACU/PCU (setup
parameters) are actually compatible for the intended satellite(s).
