Signal Name & Cable Characteristics
A.1 INTRODUCTION
This appendix defines Digital Interface Label information and electrical characteristics of input and
output signals to the CP-2500 Control Panel. Sufficient data is included to perform an electrical load
analysis for the aircraft.
Connection information identifies the connector-pin and signal names as they appear on the external
interconnect wiring diagram shown in the installation section.
