SIS™ Programming and Control

The MLC 104 Series controller can be remotely set up and controlled via a host
computer or other device (such as a control system) attached to the rear panel
Config/RS-232 port or LAN port, or the front panel Config port.

The MLC 104 or MLC 104 IP must be configured before use. As shipped the
controller can trigger basic input switching but cannot control any other devices
before being configured.

The MLC can be set up and controlled by using Extron’s Simple Instruction Set
(SIS) commands or the Extron Global Configurator software (version 2.0 or higher),
and both of those methods can be accessed via RS-232 or Ethernet LAN connection.
See chapter 2 for pin assignments and other details on the configuration and
control ports. For information on the software and the MLC’s embedded Web
pages, see chapter four.

MLC’s RS-232 protocol:

• 38400 baud

• 8 data bits

• 1 stop bit

• no parity

• no flow control

Both configuration ports require 38400 baud communication. This is a higher
speed than many other Extron products use. The Global Configurator (version

2.0 or higher) software or MLC 226/104 control software automatically sets
the connection for the appropriate speed. If using HyperTerminal or a similar
application, make sure the PC or control system connected to these ports is set
for 38400 baud.

LAN port defaults:

• MLC’s IP address: 192.168.254.254

• gateway’s IP address: 0.0.0.0

• subnet mask: 255.255.0.0

• DHCP: off

Host-to-MLC Communications

SIS commands consist of one or more characters per field. No special characters
are required to begin or end a command sequence. When the MLC determines that
a command is valid, it executes the command and sends a response to the host
device. All responses from the MLC to the host end with a carriage return and a
line feed (CR/LF = ), which signals the end of the response character string.
A string is one or more characters.

MLC-initiated messages

If you are communicating with the MLC via RS-232 or via a verbose Telnet
connection, when a local event such as a front panel selection or adjustment takes
place, the MLC responds by sending a message to the host. No response is
required from the host. The MLC-initiated messages are listed here (underlined).

(c)Copyright 2004, Extron Electronics, MLC 104 IP, Vx.xx
Day, DD Mon YYYY HH:MM:SS
Vx.xx is the firmware version number.
The MLC sends the boot and copyright messages under the following
circumstances:

• If the MLC is off and an RS-232 connection is already set up (the PC is cabled to
the MLC and a serial communication program such as HyperTerminal is open),
the connected MLC sends these messages via RS-232 when it is first powered on.

MLC 104 Series • SIS™ Programming and Control5-2

• If the MLC is on, it sends the boot and copyright messages when you first open a
Telnet connection to the MLC. You can see the day of the week, date, and time if
the MLC is connected via Telnet, but not via RS-232. If you are using a Telnet
connection, the copyright message, date, and time are followed by a password
prompt.

X1

Chn
The MLC sends this response when an input is switched.

(where X1 is the input number)

Password information

The “ Password:” prompt requires a password (administrator level or user level)
followed by a carriage return. The prompt is repeated if the correct password is not
entered.

If the correct password is entered, the unit responds with “
Administrator
If passwords are the same for both administrator and user, the unit will default to
administrator privileges.

” or “ Login User ”, depending on password entered.

Error responses

When the MLC receives a valid SIS command, it executes the command and sends
a response to the host device. If the MLC is unable to execute the command
because the command is invalid or it contains invalid parameters, it returns an
error response to the host.

The error response codes and their descriptions are as follows:
E01 – Invalid input channel number (the number is too large)

E12 – Invalid port number
E13 – Invalid value (the number is out of range/too large)
E14 – Not valid for this configuration
E17 – System timed out
E22 – Busy
E24 – Privilege violation
E25 – Device is not present
E26 – Maximum number of connections has been exceeded
E27 – Invalid event number
E28 – Bad filename or file not found

Login

PRELIMINARY

Error response references

The following superscripted numbers are used within the command descriptions
on the following pages to identify commands that may respond as shown:

14

= Commands that give an E14 (not valid for this configuration) response if the

MLC’s current configuration doesn’t support that command

22

= Commands that yield an E22 (busy) response.

24

= Commands that give an E24 (privilege violation) response if you are not logged

in at the administrator level.

27

= Commands that may yield an E27 (invalid event number) response.

28

= Commands that may give an E28 (file not found) response.

Command Tables

Using the command/response tables

The MLC 104 IP can be controlled via either a Telnet (port 23) connection or a Web
browser (port 80) connection. All MLC 104 Series models can be controlled via

5-3MLC 104 Series • SIS™ Programming and Control

SIS™ Programming and Control, cont’d

RS-232. The ASCII and URL commands listed in the tables starting on page 5-8
perform the same functions, but they are encoded differently to accommodate the
requirements of each port (Telnet or browser).

The following ASCII to hexadecimal (HEX) conversion table is for use with the
command/response tables.

ASCII to HEX Conversion Table

•

ASCII to Hex conversion table

The command/response tables list valid ASCII (for Telnet or RS-232) command
codes, the corresponding URL (uniform resource locator) encoded (for Web
browsers) command codes, the MLC’s responses to the host, and a description of
the command’s function or the results of executing the command.

PRELIMINARY

• Upper and lower case characters may be used interchangeably in the command
field unless otherwise specified.

• Commands may be sent back-to-back without spaces (for example, 2!65V1Z).

• Numbers can be entered as 1, 2, or 3 digits, e.g., 8V = 08V = 008V.

• There are a few differences in how to enter the commands depending on whether
you are using Telnet or a Web browser.

• When using these commands through a Web browser, the URL reference
is used to shorten the examples. “URL” refers to the full URL of the
control interface and Web page reference including all path information
(e.g., http://192.168.100.10/myform.htm).

• To send any of the commands using a Web browser you must prefix them
with the full URL followed by ?cmd=.

• For control via a Web browser, all non-alphanumeric characters must be
represented as the hexadecimal equivalent, %xx, where xx represents the
two-character hex byte. For example, a comma (,) would be represented
as %2C. Characters such as %, +, and the space character ( ) must be
encoded as hex bytes, or they will be misinterpreted by the MLC.

• Some characters differ depending on the method you use to send the
commands:

Telnet Web browser

Escape (hex 1B) W [must not be hex encoded]
Carriage return (hex 0D) Pipe character ( | ) [must not be hex encoded]

With Telnet you can use either an “Escape” command or a “W” command, and
the carriage return or the pipe character. With the Web browser, you are
required to use a “W” command and the pipe character.

In either method, {Data} = Data that will be directed to a specified port
and must be hex encoded if non-alphanumeric.

If you make adjustments (changes to volume, etc.), whether via the front panel
or via RS-232 or IP communication, it will take 1 minute 40 seconds (100
seconds) for the data in the MLC’s RAM to be saved to flash memory.

represented as two ASCII characters (two bytes)

Ports:

01 = rear host (Config/RS-232 port)
02 = front panel Config port
03 = slaved switcher (MLS port)
04 = projector port (Proj RS-232/IR)

= Command data section.

For Web encoding only: data will be directed to the
specified port and must be encoded (URL encoding)
if it is non-alphanumeric. Change any non-
alphanumeric character (%, +, |, , etc.) within
the data section into the corresponding hexadecimal
equivalent, %xx, where xx represents the two­character hex byte. For example, a space (hex: 20)
would be encoded as %20 (hex: 25 32 30) and a plus
sign (hex: 2B) would be encoded as %2B or hex 25
32 42.

= Greenwich Mean Time (GMT) offset value

(-12.00 to +14.00) represents the time difference
in hours and minutes (+/-hh:mm) relative to
Greenwich, England. The leading zero is
optional. For example, 5:30 = 05:30. Do not use
a plus (+) sign if the GMT offset is positive.

= On/off status

0 = off/disable
1 = on/enable

= Volume level (0 – 100 steps). When no MLS is

detected at the MLS port, the range is limited by
the max. volume command (X*47#).
Default volume = 40 when no MLS switcher is
detected at the MLS port.
Default volume = 100 when slave mode (X*41*)
is active and an MLS switcher is detected at the
MLS port.

= Version (typically listed to two decimal places,

e.g., x.xx)

= MLC’s name. The name is a text string of up to 24

characters drawn from the alphabet (A-Z),
digits (0-9), and minus sign/hyphen (-). No
blank or space characters are permitted as part
of a name. No distinction is made between
upper and lower case. The first character must
be a letter. The last character must not be a
minus sign/hyphen.

disabled (by default) in order to reduce the amount of communication traffic on the network. If you want to use the verbose mode with a controller connected via Ethernet, this

mode must be set to “on” each time you reconnect to the controller.

Example:

Get a connection listing

This command is optional. You do not have to use this command to set up the MLC. By default during configuration, the configuration software associates the main event script

file (0.EVT) with hardware events and button presses. Once that event file has been compiled, it is capable of receiving information from the MLC’s register that tracks hardware

actions and button presses. In response to a detected button press or other hardware happening, the event script can then tell the MLC to issue commands, or make some other

change. You would use this command only to associate a different event script file with tracking and responding to hardware/button actions.

Button press/release emulation

Emulating a button press or release causes the commands and actions that are associated with the button via the main
event script to be executed. Button emulation triggers only what has been set up via the Button Config. part of the
Windows-based configuration program or via Global Configurator 2.0 or higher. Emulation does not trigger the built-in
SIS input switching commands (

See the diagrams below and on the next page to determine the number of the memory block associated with each button.

The input button register numbering shown in the following illustrations is for a stand-alone MLC.

mode simultaneously.

The Repeat while held every... feature found in the configuration software (in the Button Config. tab) and Global
Configurator 2 is based on this command. However, through scripting the MLC sets the repeat mode on in response to
a specific button press, and it sets the repeat mode to 0 when the button is released or input is no longer selected.
