(g) Performance Management Bus Interface
The TCAS 3000 computer contains a low speed ARINC 429 bus input
(RMP6A,6B) that is reserved for connection to a performance management
system. The input is provisioned to obtain maximum rate of climb information
from a FMS or Performance Management System (PMS.) The input is provided
for future system enhancements and is currently not used.
(h) Magnetic Heading/Attitude Bus Interface
The TCAS 3000 computer contains a high speed ARINC 429 bus input
(RMP7A, 7B) that is reserved for connection to an Inertial Reference System
(IRS). The input lets aircraft heading and attitude data be input for the purpose
of providing for future horizontal maneuvers. This function has not been
implemented on TCAS II installations, so these pins are reserved for future use.
(i) Compact Flash Flight Data Recorder Interface
The TCAS 3000 computer contains a Compact Flash card interface that provides
flight data recording capability.
(j) ARINC 573 Flight Data Recorder Interface
The TCAS 3000 computer contains 12 discrete outputs that can be connected to
an ARINC 573 flight data recorder. The outputs are used to record information
during a resolution advisory event.
(k) ARINC 429 Flight Data Recorder Interface
The TCAS 3000 computer contains an interface for an ARINC 429 flight data
recorder. The flight data recorder function is activated by grounding a discrete
input pin (RMP11D) on the rear connector. With the discrete input grounded,
flight data is output as high speed ARINC 429 data on the RA Display No. 1 and
No. 2 busses. With the discrete grounded, the normal RA Display bus operation
is not available.
(l) Voice Audio Outputs
The TCAS 3000 computer contains two analog audio outputs that provide TCAS
aural traffic advisories and resolution advisories. The 8Ohm output has the
capability to supply up to 4 Watts RMS into a speaker. The 600Ohm output has
the capability to supply up to 80 milliwatts RMS into an audio distribution system.
(m) RS232 Interface
The TCAS 3000 computer has an RS232 input/output for connection to a
personal computer. The interface allows for LRU maintenance and
troubleshooting. The maintenance log and RA event log can also be
downloaded to a PC using this port. The RS232 interface is connected to the
53pin PDL connector on the front of the unit.
