IR RX Port Channels (Port 5)

I/O Send Commands

Command Description

GET INPUT

Get the active state for the

selected channels.

An active state can be high (logic high) or low (logic low or contact closure).

Channel changes, Pushes, and Releases generate reports based on their

active state. The port responds with either 'HIGH' or 'LOW'.

Syntax:

SEND_COMMAND <DEV>,"'GET INPUT <channel>'"

Variable:

channel = Input channel 1 - 8.

Example:

SEND_COMMAND IO,"'GET INPUT 1'"

Gets the I/O port's active state.

The system could respond with:

INPUT1 ACTIVE HIGH

SET INPUT

Set the input channel's active

state.

An active state can be high (logic high) or low (logic low or contact closure).

Channel changes, Pushes, and Releases generate reports based on their

active state. Setting an input to ACTIVE HIGH will disable the ability to use that

channel as an output.

Syntax:

SEND_COMMAND <DEV>,"'SET INPUT <channel> <state>'"

Variable:

channel = Input channel 1 - 8.

state = Active state HIGH or LOW (default).

Example:

SEND_COMMAND IO,"'SET INPUT 1 HIGH'"

Sets the I/O channel to detect a high state change, and disables output on the

channel.

IR / Serial Ports Channels

00001 - 00255 PUSH and RELEASE channels for the received IR code.
