Logic Input/Output Options

Logic Input/Outputs allow control from/to external GPIO style switches.

Logic Input Options

Logic Inputs are available on HMS-4X, HRM-4X and HKB-2X-X7.

Logic Input Options allow certain system functions to be remotely controlled by an external contact input (GPI).

A common use of the Logic Input Option is to assign a footswitch to the microphone on a station. This allows a user to latch certain talk keys On and then enable all with a single Logic Input, hands-free.

Assign a GPI switch (example: a footswitch) to one or more of the following buttons;

  • Talk

  • Call

  • Mic

  • Headset

Logic Inputs follow the latch configuration of the button and can be assigned to multiple buttons. They will change the current state (for example, if it is On then the switch will make it go Off).

Logic Output Options

Logic Outputs are available on HMS-4X and HRM-4X.

Logic Output Options allow assignment of sytem key presses or events to trigger a function on a system connected to the relay (GPI). For example, to key two-way radios.

System key presses on Talk, Call and SA buttons can be assigned to GPO/Relay.

Logic Output options can also be assigned to individual Channel Events:

  • Talk Event (when a user is talking on the channel)

  • Call Event (when a call signal is active on the channel).

    • A Talk/Call Event is only generated in a channel if the Action Trigger on the port is set to:

    • VOX (Program Audio)

    • Call/VOX (2/4 Wire)

o

A Talk Event also requires that the VOX is enabled on the input port.

Note: Talk Action Trigger initiated by a Program Audio Input VOX can on only be assigned to a Logic Output Option local to the device.
