About This Guide
This guide provides detailed information and best practice recommendations about cabling
and configuring the Extron MLC 60 Series MediaLink Controllers. It provides reference
information about specifications, dimensions, and programming of the controllers.
Throughout this guide the general terms “MLC” and “controller” are used interchangeably
to refer to any MLC 60 Series controller. “MLC D models” applies to the MLC 62 RS D,
MLC 62 IR D, and the MLC 64 RS VC D. “MLC 62” applies to all MLC 60 Series models
except the MLC 64.
About the MLC 60 Series MediaLink Controllers
The Extron MLC 60 Series MediaLink Controllers are panels that control a wide range of
audio/video systems in any classroom, meeting facility, or auditorium via RS-232 or IR. They
act as extended remote control panels, featuring eight (optionally six) labeled backlit buttons
for the MLC 62 models or six for the MLC 64 RS VC D. These buttons can be configured via
the MLC Windows®-based configuration software to control power, input switching, and
volume on a display device or switcher. If desired, you can replace these buttons with ones
having different labels, which also are provided with the controller.
The MLC 64 RS VC D model has, in addition to the configurable buttons, a volume control
module containing an analog volume control knob and a Mute button. An Extron amplifier
can be connected to this module for volume control via the MLC.
All models can control a projector, display, or switcher via IR. In addition, the MLC 62 RS
models can control display devices, switchers, and various other items such as lights, a
projector lift, or a motorized screen via RS-232, IR, relays, or digital input.
The MLC controllers are housed in secure, compact, one-gang and two-gang sized
enclosures, which can be mounted on a wall or furniture, with or without an electrical
junction box or mounting bracket.

Figure 1. MLC 60 Series Models
MLC 60 Series MediaLink Controllers • Introduction2
The five MLC models have the same button functionality and use the same configuration
software. All models can be controlled by pressing the front panel buttons or via a host
device using RS-232 communication and simple ASCII commands (Simple Instruction Set,
SIS™). They differ from each other in the following ways:
• The MLC 62 IR D rear panel does not contain the Relay, Digital Input, or RS-232
control ports that the RS models have.
• The MLC 64 front panel has seven buttons, one of which (the Mute button) is located
below the Volume knob. This button is used only to mute and unmute the volume on
an Extron amplier and cannot be congured to perform other functions.
• Some front, side, and rear panel connectors are located in different places on the
MLC RS D (US), EU (Europe), and MK (United Kingdom) models (see “Panels and
Connectors” in the “Features, Cabling, and Operation” section).
Faceplate alternatives
The MLC 60 Series models are available with the following faceplate configurations:
• MLC 62 IR D: The US IR model is delivered with two six-button faceplates in black and
white. One black and one white Decora wallplate are also provided. An eight-button
faceplate is available to order.
• MLC 62 RS D: The US RS-232 model is delivered with two eight-button faceplates
in black and white. One black and one white Decora wallplate are also provided. A
six-button faceplate is available to order.
• MLC 62 RS EU: The European model is delivered with six-button and eight-button
faceplates, both in RAL9010 white.
• MLC 62 RS MK: The UK model is delivered with six-button and eight-button
faceplates, both in white.
• MLC 64 RS VC D: The MLC 64 is delivered with seven-button faceplates in black and
white.
Features
Some of the features of MLC 60 Series include:
• Customizable buttons — Eight buttons are standard on the MLC 62 RS models,
prelabeled as shown in figure 1 on the previous page. The MLC 62 IR D has six
prelabeled buttons, and the MLC 64 RS VC D has seven.
An additional set of prelabeled buttons is included with each model, enabling the
controller to be customized to suit the application.
Additional buttons are available to order for all models, labeled in English (the default)
and other languages. Buttons can be ordered with custom labeling as well.
• Button backlighting — The front panel buttons are backlit to facilitate use in
low-light environments and to provide certain status (such as whether power is on or
off, or which input has been selected).
• Alternative six-button configuration (MLC 62 RS models only) — For
applications in which input device or button functions are not necessary, the standard
eight-button faceplate on the MLC 62 RS can be replaced with a six-button one. Each
pair of source selection buttons can be changed to a long, single function button.
• Device drivers — A wide variety of Extron certied, ready-to-use device drivers are
available via the MLC configuration software, the provided MLC software disk, and
the Extron website (www.extron.com).
MLC 60 Series MediaLink Controllers • Introduction3
• IR and RS-232 ports — The MLC 64 and the MLC 62 RS models each have a
dedicated serial port for communicating with most types of projectors or flat
panel displays via unidirectional RS-232. They also have an IR/S port, which can be
configured for IR or RS-232 control.
The MLC 62 IR D has only an IR port, which is used for IR communication only.
IR and RS-232 display drivers can be downloaded and used to configure the controller.
• Relays (RS models) — Two relay ports enable control of room devices such as lights,
motorized screens, and projector lifts.
• Digital Input (RS models) — A Digital Input port enables monitoring of a switch or
sensor to control devices.
• IR Learning — The MLC can be configured by IR learning, using the remote control
of a switcher or display device to create an IR driver that enables the MLC to control
the device.
• USB configuration port — The MLC can be congured via a USB mini B port,
located on the front or side panel (depending on the model). This port can also
temporarily provide power to the MLC during configuration.
• Volume adjustment:
• The MLC 62 models have individual Volume Up and Down buttons for audio level
control, with ve LEDs that indicate current audio settings.
• The MLC 64 has a volume control module with an analog potentiometer knob to
control the audio level for an Extron amplier that is enabled for remote volume
control. The volume control module also contains a Mute button for muting and
unmuting the audio (this button cannot be reprogrammed).
NOTE: Only Extron amplifiers can be controlled via the MLC 64 volume
control module.
• Macro capability — Each button can be congured to execute multiple actions
through the serial or IR control ports. For example, a button can be configured so that
a single press triggers commands to turn on a display, select the RGB input of the
display, and trigger a relay.
• Toggling — Buttons can be placed in toggle mode, which adds exibility by enabling
two different sets of commands to be executed with alternating presses of the button.
• Built-in speaker — A speaker provides audible feedback to confirm user actions
when buttons are pressed (except for the Mute button on the VCM module of the
MLC 64 RS VC D).
• Inactivity timer for display shutoff — An adjustable timer controls automatic
shutdown after a specified period of inactivity.
• Front panel security lockout — If the MLC is installed in an unsecured environment
where easy access is not desirable, a security lockout feature can be implemented to
lock out all front panel controls.
• Activity LED — A small LED at the top of the MLC front panel lights red, green, or
amber to indicate button presses, data transfer, front panel lockout, and other actions.
• Section 508 Compliant — The MLC meets or exceeds accessibility standards
for Electronic Information Technology. For more information about the
Extron Commitment to Accessibility, see the Extron Accessibility web page at
MLC 60 Series MediaLink Controllers • Introduction4
MLC Configuration Software
The included MLC Configuration Program is used to configure the MLC buttons and
ports via an RS-232 or USB connection. This software, provided on a DVD that is
delivered with the product, enables you to set functions for the front panel buttons
and to configure the MLC ports in order to control devices via the MLC. The software
works in combination with the IR or RS-232 drivers, also provided with the MLC on
DVD or at www.extron.com (see “Installing the Configuration Software” in the
“Software-based Configuration” section to access this program).
Device Drivers
The MLC can control a switcher, projector, or other display device via IR or RS-232
communication. The MLC must have drivers loaded for the devices it will control in order
to send commands to those devices. Drivers can be obtained in the following ways:
• You can install IR or an RS-232 driver files from a disk, download them from the
Extron website (www.extron.com), or download them from Extron via the driver
subscription feature within the Windows-based conguration program. The drivers
are saved on your computer in a folder located at c:\DocumentsandSettings\
All Users\Shared Documents\Extron\Driver2 (Windows XP) or c:\Users\
Public\Documents\Extron\Driver2 (Windows 7). You can upload the desired
drivers to the MLC using the MLC configuration software.
• You can capture IR commands from the IR remote control of a device through
IR Learning using the MLC configuration program to create a driver that the MLC
can use. When a driver is created, it can be added to the conguration program so
that the commands can be used to configure the MLC to control the device (see the
MLC 60 Series help to configure the MLC using IR Learning).

MLC 60 Series MediaLink Controllers • Features, Installation, and Operation11
Front panel features
Activity LED — This bicolored LED lights green when the MLC front panel buttons
a
are pressed. It blinks red while enabling front panel lockout (executive mode).
Display power On and Off buttons — After configuring these buttons, use them
b
to turn the connected display device or switcher on and off.
The face of the On button contains a nub (j), which helps you to identify the button
by touch. When the On button is pressed, it blinks rapidly while the connected device
is warming up. When the Off button is pressed, it blinks slowly while the device
is cooling down. When this delay period has elapsed, the power button that was
pressed remains brightly lit.
By default, only one of these two buttons can be selected (active) at once. Using the
MLC configuration software, you can associate other functions and relays with each
of these buttons (see the configuration software help file).
Volume buttons and LEDs (MLC 62 models only) — Use these buttons to adjust
c
the audio volume. Each Volume button flashes when pressed and continues to flash
while being held.
The volume indicator LEDs above the buttons give indications of change to the volume
level as follows:
• When the RS-232 or IR/S port has been congured with a serial driver that
contains a volume table, the ve LEDs light in order from left to right to show
volume level increments.
• If the current driver does not contain a volume table, the rst two LEDs on the left
blink each time the Volume Down button is pressed, and the last two LEDs on the
right blink each time the Volume Up button is pressed, indicating a volume level
decrement or increment.
Input selection buttons — These buttons can be used to select the desired audio or
d
video input for the connected device or for a variety of other functions. By default the
buttons are set up as follows:
• MLC 62 RS models: Three of these buttons are set to input mode, meaning that
they are a mutually exclusive group and only one of the buttons can be selected
(active) at a time. The active input button remains brightly lit, while all other input
buttons remain dimly lit. The fourth button, labeled Mute, is set in Toggle mode
and is not grouped with the others.
• MLC 62 IR D: Two double-sized buttons are grouped in input mode and are
mutually exclusive.
• MLC 64 RS: Four double-sized buttons are grouped in input mode and are
mutually exclusive.
You can change this button behavior by using the configuration software to change
the operating mode of the button (see the MLC 60 Series configuration program help
file for more information).
Reset LED — Indicates the status of a reset in progress.
e
Reset button — Press this reset button to initiate factory firmware or configuration
f
resets (see “Resetting the MLC Using the Reset Button,” later in this section).
MLC 60 Series MediaLink Controllers • Features, Installation, and Operation12
USB configuration port — Connect a USB cable (USB A to mini B) between
g
your computer and this port to configure the MLC via the configuration software
and to update the firmware. This port can also provide power to the MLC during
configuration.
NOTE: Do not use this port as the permanent power source for the MLC. It
should be used for power only during button and port configuration.
• On the MLC D models, the USB port is located at the right edge of the front
panel behind the wallplate. To access this port after installation, you must remove
the wallplate from the unit.
• On the MLC 62 EU and MK, the USB port is located on the left side panel. To
access this port after installation, you must detach the MLC from the installation
surface.
DIP switches — Reserved for future use
h
IR Learning sensor — This sensor enables the MLC to learn IR commands from the
i
hand-held remote control of a display device or switcher. The IR-learned commands
are used to create an IR driver, then configured to be played back with any button
press (see “IR Learning,” later in this section).
NOTE: Before performing IR Learning to create a driver, check to see if an Extron
driver exists for your device (see “Obtaining Device Drivers” in the
“Software-based Configuration” section).
j On button Identication nub — Power On button face contains a raised nub that
helps you to identify the On button by touch in a dark or dimly lit room.
k Mute button (MLC 64 only) — Press this toggle button to mute and unmute the
volume on the Extron amplifier connected to the volume control module.
l Volume control knob (MLC 64 only) — Rotate this knob to increase or decrease the
volume on the Extron amplifier connected to the volume control module.
Buttons
The front panel button illumination provides status on what the MLC is doing. The buttons
are lit while the MLC has power. When a button has been pressed and is active or on, it
lights brightly. While a button is inactive or off, it is lit dimly.
When buttons are grouped together, only the button that is pressed lights brightly. The
other buttons in the group remain dim. (See the configuration software help file for
information on grouping buttons; see “Installing the Configuration Software” in the
“Software Configuration and Control” section to obtain the software.)
You can remove buttons and replace them with buttons having different labels. You can
then configure the new buttons with the functions that their labels represent, using the
configuration software (see the MLC 60 Series configuration program help file for detailed
procedures for configuring the buttons).
Each Display On/Off and input selection button can be set up to perform a sequence of
several functions, which can be combinations of the following options:
• A driver operation — Execute an RS-232 or IR control command that is part of a
device driver (for a projector, VCR, DVD player, switcher, and so forth).
• A relay operation — Execute a relay command to a room device such as a motorized
screen or a projector lift.
• Setting a time delay — Insert delays between executed commands.
MLC 60 Series MediaLink Controllers • Features, Installation, and Operation13
• Setting the button flashing rate — Specify fast or slow flashing of a front panel
button and the number of seconds the button flashes.
NOTE: While a button is flashing, all other front panel buttons are disabled.
• A user-defined RS-232 operation — Issue a non-driver-associated RS-232 command
(one that you programmed separately), such as an SIS command, via the IR/S or the
RS-232 port.
• Button emulation — Initiate a series of button functions with a single button press.

a Host/Config port — This bidirectional RS-232 serial port can be used for
conguration and rmware updates in the same way as the USB port (g in the
“Front and Left Side Panels” section, earlier in this section). The baud rate is 9600
bps. This port can be used as a backup for the USB Conguration port (although you
cannot power a device through it).
b Digital Input port(RS models only) — This port enables the MLC to monitor
devices such as push buttons, switches, motion sensors, and moisture sensors and
provides an additional way to trigger functions on the MLC. Connect a switch or a
sensor to this 2-pole captive screw connector to initiate commands via the MLC to the
display device, switcher, or other room devices such as lights or a motorized screen.
c Relay ports (RS models only) — These relays allow control of room devices such as
motorized screens, lights, and projector lifts. They are normally open relays and are
rated at 24 V, 1 A. Low-power devices can be connected directly to the relay ports;
devices requiring more than 24 V can be connected through a third-party low-voltage
controller (LVC).
d IR/S or IR port — This port provides unidirectional communication to control a
switcher or a display via RS-232 or IR. For IR control, one or two IR emitters can be
connected with a maximum of 50 feet (15 m) distance from port to emitter.
• RS models: On all MLC 60 Series RS models, this port is labeled “Port B IR/S.” It
can be set up via the configuration software to send out unidirectional RS-232
(the default) or IR commands. In the Configuration software, this port is called
Port B (IR/S)
• MLC 62 IR D: On the IR-only model, this port is labeled “Port A IR” and issues
only IR commands. In the Configuration software, this port is called PortA(IR).
e RS-232 port (RS models only) — This serial port, labeled “Port A RS-232,” provides
unidirectional communication to control a switcher or a display via RS-232. In the
Configuration software, this port is called PortA(RS-232).
fPWR (power) connector — Connect the supplied 12 VDC, 1 A power supply (or
any other power supply capable of providing 12 VDC) to this 2-pole captive screw
connector.
CAUTIONS:• The power supply must not be permanently fixed to the building
structure or similar structures.
• The power supply must not be located within environmental air
handling spaces or the wall cavity.
• The installation must be in accordance with the applicable
provisions of the National Electrical Code ANSI/NFPA 70,
Article 725 and the Canadian Electrical Code, Part 1, Section 16.
• The power supply must be located within the same vicinity as
the Extron AV processing equipment in an ordinary location,
Pollution Degree 2, secured to a podium, a desk, or an equipment
rack within a dedicated closet.
• Always use a power supply specified by Extron for the MLC. Use
of an unauthorized power supply voids all regulatory compliance
certification and may cause damage to the supply and the MLC.

MLC 60 Series MediaLink Controllers • Features, Installation, and Operation16
Installation
The MLC 60 Series can be installed as listed below:
• The MLC 62 D models can be installed in a standard one-gang electrical wall box or a
one-gang Decora mounting bracket (“mud ring”).
• The MLC 64 RS VC D can be installed a two-gang electrical box or mounting bracket.
• The MLC 62 RS EU can be installed in a standard one-gang EU junction box.
• The MLC 62 RS MK can be installed in a standard one-gang MK junction box.
CAUTIONS: • Installation and service must be performed by authorized personnel
only. UL listed electrical boxes are recommended.
• Ensure that the junction box is grounded properly.
• When stripping wires for use with the captive screw connectors, leave
3/16 (5 mm) of bare wire to insert into the connector.
• Exposing more than 3/16 inch of the copper wires could allow the
stripped wires to touch each other, causing a short circuit. This could
result in the external DC power supply overheating and burning.
• Stripping the wires to expose less than the recommended amount
may cause them to slide out of the connector too easily, even if they
are tightly pinched by the captive screws.

To control devices via infrared (IR) commands from the MLC, connect one or two IR
emitters to the IR/S port (RS models) or the IR port (IR model). The IR and IR/S ports provide
unidirectional IR signal output to control a display, projector, switcher, or other device such
as a VCR or DVD player.
You can connect one or two single IR emitters or one dual IR emitter to the IR or IR/S port
to control one or two devices. Because the MLC captive screw plugs have small openings
that accept just one wire per pole, to connect two IR emitters to the MLC, insert one
ground wire (black) and one IR signal wire (black with a white stripe) in the MLC 62 IR or
IR/S port, then connect the IR emitters to those wires, as shown below.

To connect devices to both relay ports:
1. Connect the ground wires of both devices to pin 3 of the provided 3-pole captive
screw connector.
2. Connect the signal wire of one device to pin 2 and the other device to pin 1 of the
3-pole connector.
3. Plug the 3-pole connector into the MLC Relays port.
To define the operation of a relay and associate it with a button or a digital input, use the
configuration software (see “Adding relays to buttons” or “Configuring the Digital
Input Port” in the “Software-based Configuration” section or the configuration software
help for setup procedures).
Wiring the Digital Input Port (RS Models Only)
The Digital Input port on the MLC rear panel lets you connect a switch or sensor to control
other devices in the room that are connected to the MLC serial, IR, and relay ports. This
port measures two states — high and low — of the connection between the switch or
sensor and the connected device. The port accepts 0 to 24 VDC input. The threshold
voltages are as follows: a voltage below 1.0 VDC is measured as logic low, and a voltage
above 1.5 VDC is measured as logic high.
There is also an internal, +5 VDC, selectable, pull-up resistor for this circuit. If a connected
device does not have its own power source and will be powered through the controller,
configure this port (via the MLC configuration software) with Input with Pullup as the
digital input mode. If the connected device provides its own power, select Input for the
digital input mode (see the MLC 60 Series Configuration Program Help File to select the
digital input mode).
In addition, you can program actions on this port, so that each time a high or low state is
detected, one or more functions are performed. An example of this is front panel lockout,
or executive mode (see the configuration software help file to configure the Digital Input
port).
To wire the Digital Input connector:
1. Connect the ground port of the input device to pin 2 of a provided 2-pole captive
screw connector.
2. Connect the signal port of the input device to pin 1 of the captive screw connector.
3. Plug the wired connector into the MLC rear panel Digital Input connector.

Wiring the Host/Config Port
The Host/Config port provides an alternative connection by which the MLC can be
configured and controlled from a host device or computer. (The primary means of
configuring the MLC is through the USB port; see “Configuring the MLC via the USB
Port,” later in this section.) In addition, SIS commands can be issued through this port
from the computer to control the MLC (see the “SIS Control” section).
The RS-232 protocol for this connection is 9600 baud, 1 stop bit, no parity, 8 data bits, no
flow control.
Use a female 9-pin to bare wire RS-232 cable or a universal control cable (such as
UC 50', Extron part number 26-518-01, or UC 100', part number 26-518-02) to connect
a Windows-based PC or an RS-232 control system to the MLC via this 3-pole, 3.5 mm
captive screw connector as follows:
1. Wire the RS-232 cable to one of the 3-pole captive screw plugs provided with the
MLC, as follows:
• Receive wire to pin 1, which plugs into the Tx (transmit) port
• Transmit wire to pin 2, which plugs into the Rx (receive) port
• Ground wire to pin 3, which plugs into the _ (ground) port

Mounting the MLC EU in a Raceway Using Spacers (Optional)
If you are experiencing difficulty with the MLC EU staying in place when installed in a
cable raceway, this may be due to a gap between the metal mounting bracket and the
wall frame.
When this gap exists, the tabs on the sides of the MLC do not reach the metal mounting
bracket and the MLC does not snap completely into the wall frame.
You can remedy this situation by installing a spacer (provided with the MLC EU) between
the metal mounting bracket and the rim of the junction box. This spacer appears very
similar to the metal mounting bracket, except that it has holes instead of slots for the
mounting screws, it is engraved with the words “Optional Spacer” and “Place behind
bracket,” and has a slightly larger center opening than the mounting bracket.
NOTE: Do not attempt to use the spacer in place of the metal mounting bracket.
Because of its larger opening, the spacer will not hold the MLC EU in place in
the wall frame.
MLC 60 Series MediaLink Controllers • Features, Installation, and Operation36
To mount the MLC EU to a raceway using the spacer:
Raceway
1. Mount the electrical box in the raceway.
2. Attach the spacer to the electrical box using two
of the included screws in the holes at the sides
of the spacer. Leave the screw heads protruding

About the MLC Configuration Program
An MLC controller must be configured in order for it to be able to control other devices.
The Extron MLC 60 Series Configuration Program is used to set up the MLC front panel
buttons and rear panel ports and to update firmware. Using this software, you can create
configurations on your computer for your MLC and then upload them to the computer via
the MLC USB or Host/Config serial port. (The MLC does not have to be connected to the
computer while you are creating the configurations.) See the “Features, Installation, and
Operation”section for pin assignments and other details on the configuration ports, and
the configuration software help file to create and upload the configurations.
NOTE:Extron recommends configuring and controlling the MLC via the USB port.
This port can supply power to the MLC during the configuration process.
Computer System Requirements
The minimum system requirements for the computer on which you install the MLC
configuration program include:
• Intel Pentium III 1-GHz processor
• Microsoft Windows XP SP2 (32 bit) or Windows 7 (64 bit)
• Microsoft.NET Framework 2.0
• 512 MB of RAM
• 50 MB of available hard disk space

Starting the Configuration Software
To use the MLC to control devices, you must create one or more configurations for it,
using the MLC configuration program. A configuration is a set of specifications for button
command assignments and port parameters that enable the MLC to control your display
device or switcher.
NOTE: Configurations can be created away from the job site and without the MLC
being connected to the computer.
After you have downloaded and installed the software (see “Installing the
Configuration Software,” earlier in this section) and device drivers if necessary (see
“Obtaining Device Drivers,” later in this section), begin by creating a new project.
An MLC project is a file (with an .mlp extension) that contains port and button
configurations for one or more MLCs. A configuration must be created within a new or
existing project. A project can be saved, copied, and edited (for example, by adding or
changing configurations within it). You can also create a configuration and add it to an
existing project. You can start a new project either when first opening the MLC software
or while the software is open and another project is active.
To start the configuration program:
1. Open the MLC 60 Series software by selecting the MLC icon from the Start menu on
your computer desktop. Select AllPrograms\ExtronElectronics\MLC60\MLC60.
The Start Options window opens in front of the MLC 60 Configuration Program main
window.
2. On the Start Options window, select the Create a New Project radio button.
Figure 48. Start Options Window
3. Click OK. The Add Device dialog box opens, displaying a diagram of your MLC front
panel.
4. On the Add Device window, enter a name for your MLC in the DeviceName field.
This becomes the name of the first configuration in the new project.

Obtaining Device Drivers
The Extron drivers are control files (libraries) of commands created by Extron that are
specific to a particular display device or switcher. There are different sets of drivers for
serial (RS-232) and IR control. Before you can use the configuration software to configure
the MLC buttons and ports, the necessary drivers must be loaded onto your computer. You
must then load the appropriate driver for your device to the MLC in order to configure it
to control the device.
Serial and IR drivers are available at no charge from the Extron web site at
www.extron.com. You can download them directly from the web or through the
configuration software. The same drivers are also provided on the software DVD provided
with the MLC.
NOTES: By default,the drivers that you download are stored in the Driver2 folder on
your computer, located at:
• Windows XP — c:\DocumentsandSettings\AllUsers\
Shared Documents\Extron\Driver2
• Windows 7 — c:\Users\Public\Documents\Extron\Driver2
Downloading Drivers Using the Configuration Program
The easiest way to obtain the drivers for your devices is via the MLC configuration
program. (You can do this at any time while the software is open, regardless of whether a

SIS Control
The MLC can be remotely controlled via a host computer or other control device that is
attached to the MLC rear panel Host/Config port. You can issue Simple Instruction Set (SIS)
commands to the MLC via the RS-232 or USB interface of your computer or control device
with a communication software program such as Extron DataViewer or HyperTerminal. This
section contains a list of the SIS commands available for the MLC and describes procedures
for issuing them. The following topics are covered:
• Host-to-Controller Communications
• Using the Command and Response Table
• Command and Response Table for SIS Commands
Host-to-Controller Communications
SIS commands consist of strings 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.
Most 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.
Controller-initiated Messages
When a local event such as a front panel button press takes place, the MLC responds by
sending a message to the host, indicating what selection was entered. No response is
required from the host.
The MLC sends the following copyright message only when it first powers on.
where MLC nn is the model name, vn.nn is the firmware version number and 60-nnnn-nn
is the model number.
This message does not appear with a USB connection.
Error Responses
If the MLC is unable to execute a command it receives because the command is invalid
or contains invalid parameters, the controller returns an error response to the host. This
response consists of the letter E followed by a number and a carriage return with a line
feed. The following error response codes can be returned:
E10 – Invalid command or parameter
E13 – Invalid value (out of range)
E14 – Not valid for this configuration
E22 – Busy
MLC 60 Series MediaLink Controllers • SIS Control54
Using the Command and Response Table
The Command and Response Table on the following pages lists valid ASCII command
codes, the responses of the MLC to the host, and a description of the command function
or the results of executing the command. The ASCII to HEX conversion table below is for
use with the table.
