SPECIFICATION & OPTIONS INTRAC-305

OPTIONS		A number of options are available for the INTRAC-305.
		The options are described in the following pages. Some of
		these options require changes to the firmware or hardware
		and some are only available when ordered at the time of
		initial order.
		Serial Interfaces only need a change to switch and / or
		connector positions within the INTRAC.
Voltage		The power supply unit (or units for Dual Redundant PSU
		option) of the INTRAC-305 auto switch for nominal mains
		voltages of 110Vac or 220Vac.
Tracking Signal		The INTRAC-305 can be supplied with an integral L-band
		beacon receiver (IBRL). Alternatively a voltage, from an
		external receiver, which varies directly with the received
		signal strength in dB may be used. The IBRL option should
		be specified at time of initial order.
Serial Interfaces		There are three communication ports on the INTRAC-305,
		“Remote Port”, “Test Port 1” and “Test Port 2”. The Remote
		Port is configured for RS232/RS423. Test Ports 1& 2 can be
		independently configured as either RS423 or RS422.
		This involves connecting the rear panel connectors to the
		appropriate connectors on the main board and setting the
		option links as shown below.

Polarisation	If the antenna has motorised polarisation the INTRAC can be
	user configured to control the polarisation angle. Polarisation
	uses the standard Andrew polarisation resolver.
Note	The standard version of the INTRAC-305 is firmware
	configured for a Pol resolver geared 1:1 to the polarisation
	tube. Firmware for a Pol resolver geared 2:1 to the
	polarisation tube is available if required. Note this is a
