Page 16: Installation Planning
INSTALLATION PLANNING The ST3453H has been designed to ensure maximum interoperability with external avionics. Contact Sandel with any questions about interfacing to specific avionics equipment not covered in the installation drawings in this manual. General Information To simplify installation, after signals are wired to the ST3453H pins, on-screen setups are used in a post-installation procedure.
Page 17 ohm resistance check on ground pins to airframe ground; and presence of inverter 400Hz (if used) only on the appropriate pins.  Review any special items particular to the subject helicopter installation.  Power up the ST3453H in maintenance mode and sequentially access each maintenance page to select the installed equipment.
Page 18: Interface Functions
INTERFACE FUNCTIONS Power The primary power is 28 volt dc on J1-P and is supplied from the aircraft avionics buss through a circuit breaker. Ground is provided on J1-R and should be attached to an approved airframe ground. A 26 volt 400Hz excitation input is available at J1 - W. It is only used in the case of an XYZ heading source.
Page 19: Glideslope
Glideslope This input provides the GPWS mode-5 glideslope alert. MIL-STD-1553, ARINC 429 or low level analog inputs for Glideslope deviation, Glideslope flag status, and Localizer and Localizer Flag are provided. An additional discrete input is available for Back Course from the HSI, which acts to disable Glideslope alerting while on a Back Course approach.
Page 20: External Annunciator-Only Functions
