NOTE: For CM 2000 Configuration Modules used in ART 2000 Weather
Radar and KRA 405B Radar Altimeter Installations and CM
2000 configuration modules that have never been pro-
grammed or may have a default program for a different
unit, a "write to" initialization must be performed be-
fore writing the parameters required for the installation
into the CM 2000 configuration module. From the File menu,
load the default RDR 2000 or KRA 405B file into memory
and perform a "write to" from the hardware menu. This will
ensure that a correct default program, without errors, is
present. The default program can then be modified from
View in the memory menu. Refer to sections 1.4.2.1,
1.4.2.2, and 1.4.2.3 of the KPA 900 operators guide (006-
05392-OOXX).
C. KPA 900 CONFIGURATION MODULE PROGRAMMER KIT
A KPA 900 Configuration Module Programmer Kit, Part Number 050-
03311-0002, is necessary to input configuration data to the
Configuration Module. This must be completed before the module is
installed. For operational procedures refer to KPA 900 Operator’s
Guide, Part Number 006-05392-00XX (XX = Latest Revision).
D. DH AUDIO OUTPUT
The KRA 405B (066-01153-0202) provides an audio output which some
operators prefer to the visual indication of Decision Height. The
audio output is intended to be connected to an audio panel as an
aural indicator of Decision Height. The audio is enabled by
connecting the DH Tone Enable discrete to an indicator such as the
KNI 415/416 which provide a switched external DH line. Audio is
enabled by pulling the discrete low; <3.5Vdc. The frequency of the
tone and the duration are controlled internally by software. See
Note 15, FIGURE 2-17 KRA 405B RADAR ALTIMETER SYSTEM INTERCONNECT ,
for more information. FIGURE 2-16 EXTERNAL SONALERT shows an
external sonalert installation.
2.5 KRA 405B SYSTEM INSTALLATION
A. KRA 405B RECEIVER/TRANSMITTER
Select the KRA 405B Receiver/Transmitter installation location. The
unit may be mounted rigid, but if shock mounting is desired, allow
adequate sway space. Always allow one inch of free air space around
the top and rear of the unit.
