(host to MLC) (MLC to host)
Send/receive data to/from page 0 memory
Send 80 A0 [16k bytes of data] Dnl0 The host downloads 16k bytes
of binary data to page 0 of the
MLC’s memory.
Receive 80 A1 The MLC sends 16k bytes of
binary data to the host.
Send/receive data to/from page 1 memory
Send 80 A2 [16k bytes of data] Dnl1 The host downloads 16k bytes of binary
data to page 1 of the MLC’s memory.
Receive 80 A3 The MLC sends 16k bytes of
binary data to the host.
Send/receive a segment (256 bytes) of data (a segment relating to a single button)
Send 80 A6 ?? [256 bytes of data] Seg0 The host sends 256 bytes of
binary data to the MLC.

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.
