Discrete Inputs*
The GDL 82 has two active-low discrete input pins denoted with an asterisk (*). The following signal conditions are
required for the states of those inputs:
•
Active (low) state: Input signal is < 1.0 VDC and/or resistance to ground < 375
ohm
•
Inactive (open/high) state: Input signal is between 2.0 VDC and 33 VDC and/or resistance to ground > 130 kilohm
5.2 Functional Descriptions
5.2.1 Power and Antennas
This section provides power input requirements and antenna connections. Refer to section 10 for interconnect
