P101 Main Channel Signal Definitions
Console 1 M Keying (/PTT) (C1PTT)
Logic signal from Console
Low = PTT on Main Channel
Console 1 Coded/Clear
Logic signal from Console
Low = Coded TX Main Channel
High = Clear TX Main Channel
Console 1 TX Audio Tip & Ring
600 Ohm (Or Bridging) TX Audio from Console (Main
Channel)
RX Voted 1-8
Logic signals from comparator
Low = Voted
Instant Mode
Logic signal from Console
Low = Instant TX Update Mode
RPT DISABLE
Logic signal from Console
Low = Disable Repeater Operation
High = Enable Repeater Operation
(if programmed)
RPT KEY
Logic Output from TSAM (Not normally used)
Low = PTT during Repeat operation
Console 1 PTT Out COM & N.O
Relay contacts active when C1PTT is active.
FORCESEL
Logic signal from Console (used with /TXS1-8)

This tells the TSAM to use the /TXS1-8 lines as inputs.
Holding this line low also disables automatic steering.
TX Sel 1-8 /TXS1-8
Bi-directional logic signals
To/from Console (Main Channel)
Outputs from TSAM (when FORCESEL is High):
Low = Selected TX
Inputs to TSAM (Read on low-going FORCESEL):
Low = TX to force select
TX 1 - 8 Audio Tip & Ring
600 Ohm TX Audio Outputs to Transmitters
(Main Channel)
Gnd
Negative Ground (common for all logic signals)

Logic signal from Console
Low = Coded TX Secondary Channel
High = Clear TX Secondary Channel
Console 2 TX Audio Tip & Ring
600 Ohm (Or Bridging) TX Audio from Console (Secondary
Channel)
Gnd
Negative Ground (common for all logic signals)
