DESCRIPTION
BIA-32 Bearing Interface Adapter
Accepts CSDB or ARINC 429 digital bearing from ADF or VOR, and CSDB
or ARINC 429 or three-wire synchro heading information. The output of the
adapter is three-wire synchro or sin/cos AC relative bearing-to-station signals.
May be used with the VIR-32, VIR-33, VIR-432, VIR-433 or ADF-462.
CAD-31 Control Adapter
Accepts CSDB input and outputs 2x5 VHF COMM or NAV tuning information
for VHF COMM or navigation system updating. May be used with the VHF-20( ),
VIR-30( ) or VIR-31( ).
CAD-62 Control Adapter
Converts CSDB to transponder code, or converts CSDB to ADF frequency
Binary Coded Decimal (BCD). May be used with TDR-90 or ADF-60.
DDA-42 Distance Data Adapter
Input: CSDB output from DME-42.
Output: Distance in 40 mv/nm, six-wire (ARINC 568) and pulse pair format
for a single channel.
RAC-870 Radio Altimeter Converter
Converts analog altitude data from the ALT-55B or ALT-1000 radio altimeter
into an ARINC 429 serial format.
SIU-80 Serial Interface Unit (-001)
Converts data between CSDB and ARINC 429 bus formats and from ARINC
568 DME to CSDB and ARINC 429 bus formats.

SIU-80 Serial Interface Unit (-003)
Similar to -001 but converts specific CSDB/429 autopilot signals. Contact
Rockwell Collins for specific interface requirements.
SIU-80 Serial Interface Unit (-004)
Similar to -001 but converts 6-wire TACAN signals to CSDB/429 for VOR/DME
formats. Contact Rockwell Collins for specific interface requirements.
WXA-1000 Weather Radar Adapter (-001)
Provides the interface needed to display ARINC 453 Enhanced Ground Proximity
Warning Systems (EGPWS) formats on a system that is equipped with a non-ARINC
453 Weather Radar Control Panel like the WXP-85( ). May be used with EFIS-84/85/86,
WXR-350 and EGPWS with slow raster timing.
WXA-1000 Weather Radar Adapter (-021)
Similar to -001 but for EGPWS with fast raster timing.

Inputs | | | | PRGM
COM | Return line for grounding strap option inputs. | | | 453 Control Data Input | High-speed digital bus that carries control
data and processed terrain information from the EGPWS to the WXA-1000. Data
is transmitted in 1600-bit words at a 1 megabit/s rate. | | | WXA
Data B (Ext Load) | Use this input instead of
J2-19 for the side B connection of the ARINC 453 bus when connecting a second
WXA to the bus. This input provides additional resistance to maintain the
bus impendance at 70Ω. Not used in a single WXA-1000 installation. | | | Left/Right (F) | Strap input for left-side/right-side
identification. Connecting this input to PRGM COM (J2-12)
identifies the unit as the right-side WXA. Left open, unit is identified as
the left-side or single WXA. | | | EFIS
Ready (F) | Active low input from the
new EFIS systems that control the start of the next raster update cycle. The
raster update cycle normally starts when this line returns to high, but internal
timing circuits will intervene to start the raster cycle after 50 ms if the
EFIS has not released the input. Ground = hold off raster; open = start raster
or use 60-Hz timing. | | | WXP-85 Data | Serial 4-wire data bus from the
WXP-85( ) that contains range and mode information | | | WXP-85
Clock | Serial 4-wire data bus from the WXP-85( ) that contains

supplied to the raster control circuit in the EFIS display. 128 cycles of
52 µs low and 7 µs high for
-021 (11 µs for -001) occur within each 7.5 ms high
period of the WXA Busy signal. The signal remains high during the 9.1 ms low
period of the WXA Busy signal. | | | WXA Busy | Vertical deflection signal supplied
to the raster control circuit in the EFIS display. Signal is high for 7.5
ms of the 16.6-ms period for -021 (17.25 ms for -001). | | | WXA
Data | 4-wire serial digital data bus that carries annunciator
data (range, mode, etc.) to the EFIS system | | | WXA Clock | 4-wire serial digital data bus
that carries annunciator data (range, mode, etc.) to the EFIS system | | | WXA
Shadow | 265 µs pulse that is generated
with the rising edge of each WXA Busy pulse. This signal is used to charge
an integrator circuit in the EFIS that varies beam intensity from minimum
at the shortest range to maximum at the longest range. | | | WXA Retrace | Horizontal deflection signal supplied
to the raster control circuit in the EFIS display. This signal is low for
7 µs high for -021 (11 µs for
-001) and then high for 52 µs. The signal runs continuously
at this duty cycle. | | | WXAZ
Red | Video output that controls the red color gun in the
EFIS display. | | | Range Mark | Control signal to the EFIS that
displays the range mark. This signal is a 52-µs pulse
that occurs at the center of each WXA Busy high period. | | | WXAZ
Blue | Video output that controls the blue color gun in the
EFIS display. | | | | WXAZ Green | Video output that controls the green color gun
in the EFIS display. | | | | 429
Control Data Output | Serial digital
bus that carries mode and range control data to the EPGWS. Data is transmitted
