Initiate or abort IR learning

Learn ready 80 B0

LrnRdy Initiate IR learning.

LrnTimOut Timeout during IR learning.

LrnRetry Retry IR learning. (Aim remote

control at MLC, press button again.)

LrnFail IR learning has failed.

LrnOK IR learning has succeeded.

Abort learning 80 B1 Lrn Abort Abort IR learning.

Set pass-through/normal mode

Set to pass-through mode 80 C0 Hst1 Set the MLC to RS-232 pass-

through mode. RS-232 commands

will go directly to a connected

Extron MLS switcher for direct

control of switcher settings.

Set to normal mode 80 C1 Hst0 Set/reset the MLC to normal

mode. RS-232 commands are

processed by the MLC.

Activate a memory block (segment)/emulate a button press

Activate a block 80 D0

IRSnd*

??d

Activate/trigger a memory

block. (Send the command

stored at that address).

Emulate a button press 80 D1

Btn

??d

Simulate pressing a button.

(Send the command and/or

perform the function [relay

triggering] stored in the block.)

indicates the block number in hex notation where

can be 0 to 7F (hex)

(0 to 127 decimal).

??d

indicates the block number in ASCII numeric notation.

The responses shown are ASCII.

Command/response table for advanced instructions

(for the Windows-based control program)

Data downloads/uploads are initiated by sending a series of hex commands to the

host RS-232 port of the MLC. The Windows-based control program uses these

commands mainly to load and save driver data and system configuration settings.
