MT101-114/115/117
Front Panels for the MultiTasker
12-Slot Enclosure
The MT101-114, MT101-115, and MT101-117 are
currently the three front panels available for the
MT100-108, 12-Slot MultiTasker. The front panel is
ordered separately based on the best solution for
the particular application.
Select the MT101-115 panel for applications in
which the MultiTasker needs to be controlled from
the front panel. This panel provides 36 keys which
are user-programmable. This is accomplished by
connecting a computer to the MT101-115 through
its 9-pin D-Sub RS-232 communication port and
programming the functionality of each key using
Windows®software provided by ALTINEX. In
applications where more power is required, the
MT101-117 should be used.
Once programmed, the keys can be used to affect
the pre-programmed switching functions and
operational functions such as press,
press-and-hold, and turning LEDs on and off. The
keys offer removable transparent faces allowing
access to removable labels for easy identification of
programmed functions. The key layout on the
MT101-115/117 resembles a typical switcher or
matrix switcher configuration with larger keys used
for input/output control and smaller keys used for
special features.
The MT101-114 panel can be used f or applications
in which the MultiTasker will only be controlled with
a computer or third-party control system. Although
it does not offer any keys, it does have the main
microprocessor for the MultiTasker installed on the
inside of the panel which is required for external
RS-232 control of the MT100-108.

INSTALLING YOUR MT101-114/115/117 6
Step 1. Turn off power to the MultiTasker
enclosure and disconnect from AC power.
WARNING! ALWAYS DISCONNECT
THE AC POWER CORD BEFORE
OPENING THE ENCLOSURE.
Step 2. The electronic components inside the
enclosure and front panel are
static-sensitive. Please take precautions
to avoid electrostatic discharge (ESD).
Step 3. Remove the 6 screws on the front panel
to access the cables inside the enclosure.
Avoid handling the panel by the circuit
boards; handle by the metal panel only.
Step 4. Follow the connector orientation
illustrations shown in the Installation
Instructions on page 5.
CAUTION! Avoid possible electrical
damage by ensuring that all header pins
are aligned properly before restoring
power.
Step 5. After connecting the cables, fasten the
panel to the enclosure with the 6 screws
removed previously. Be careful not to
pinch any cable between the panel and
the enclosure.
Step 6. If a PC or control system is used to control
the cards in the MultiTasker, connect the
9-pin D connector of the
MT101-114/115/117 to the control
system’s RS-232 port.

OPERATION 7
The key programs and subroutines described in
this section may be programmed on-the-fly or
saved in a text file and downloaded to the
MultiTasker using communication software such as
MTSetup or AVSnap®. The sample program file
shown in DIAGRAM 2 is a simple matrix control
including volume control for an audio card. Use this
example to see how keys and subroutines are
typically programmed and organized.
7.1 TERMINOLOGY
The terms below are used to increase the legibility
of the descriptions used in this section of the
manual.
Cn This term refers to a MultiTasker card
where the ID number is n. Typically, “n”
is the slot number of the card, but may
also be an assigned value. Example:
C1, C2, C3, etc.
Gk This term refers to a group of cards
where “k” is the group number. Groups
are defined using the write group
command [WR]. The possible groups
are G1-G8.
Ui This term refers to the ID number of a
MultiTasker enclosure. The value of “i”
may be a value from 0 to 20 where 0 is
the default value in single MultiTasker
systems.
string A string is one or more text characters
that form a command, describe output
data, or refer to incoming feedback.
feedback Feedback refers to text data that is
received from the MultiTasker or any of
the cards installed in the enclosure.
RXD (Receive) Transmit
TXD (Transmit) Receive
Step 7. Turn on the power switch of the
MT101-114/115/117 MultiTasker. The unit
is now operational.
400-0402-003
Sub This term is an abbreviated form for
subroutine. A subroutine is a section of
memory used to store commands that
control the cards within the enclosure.
Example: SUB1, SUB2, etc.

MULTITASKER
7.2 MT101-114/115/117 OPERATION
This section describes the programming and
control functions for the MT101-114, MT101-115,
and MT101-117. The MT101-114 has the same
programming capabilities as the MT101-115/117
with the exception of the key and LED functions.
On the MT101-115/117, the front panel uses 36
programmable keys to control plug-in cards. Each
of the 36 keys has five states. A total of 180
subroutines are available to perform different
functions based upon each key's state.
IDENTIFY UNIT ID
The [IDUi] and [IDU] commands can be used to
locate a specific unit on the RS-232 bus. See the
[IDUi] and [IDU] commands for details.
POWER-UP SUB1 (U0/U1)
SUB1 is always executed at power-up or on the
reset command, [RES]. Typically, SUB1 is used to
place the system cards to default settings. See the
{WRS} command for programming details.
KEY PROGRAMMING
Each key may be programmed to execute one
subroutine for each of the five key states. See the
{WRK} command for details.
State 1 Key is pressed and LED is OFF.
MATRIX KEY CONVENTIONS
The front panel is designed to use the center
group of keys for Matrix card input and output
selections.
Input Selection = Keys 13-28
Output Selection = Keys 29-36
Card Selection = Keys 7-12
Using these conventions, the LEDs will flash
automatically showing each connection after a
completed input-to-output command has been
issued. The user should NOT issue LED
commands to these LEDs during these
sequences.
MEMORY
The memory is used to save key and subroutine
programs. It is non-volatile and has a storage
capacity of 64KB. The only size restriction of an
individual subroutine is that of overall available
memory.
SAVING CARD CONFIGURATIONS
Commands used for MultiTasker cards such as
[ON], [OFF], and [IO] that end in "S" will be
saved to the memory of each card. Commands
not ending in "S" will be executed but not
restored when the system is reset or powered
off, and then on again.
State 2 Key is pressed and LED is ON.
State 3 Key is pressed and LED is FLASHING
State 4 Key is Pressed and Held for 2.5 sec.
State 5
400-0402-003
Key is Pressed and Held for 2.5 sec
during power-up.
SUBROUTINES AND FUNCTION TYPES
The subroutine for a key may be programmed to
execute a complete function "I1O2C3" or a
portion of a function. As an example, matrix
functions will use one key to select the input
number, "I1", another key to select the output
number, “O2", and a final key for the group/card
ID, “C3”. See the {WRS} command for further
details.
Complete and incomplete functions mean two
different types of subroutines. Subroutines with
complete functions contain one or more
stand-alone functions which are all executed
with a single key press. Subroutines with matrix
functions require two or more keys to be
pressed to complete a single executable
function.

7.3 RS-232 CONNECTION
7.3.1 RS-232 COMMUNICATION
If a control system is used to control the cards in
the MultiTasker, connect the 9-pin D connector
of the MT101-114/115/117 to the control
system's RS-232 port. In order to connect the
MultiTasker (MT) to a computer or a terminal,
you must have the proper interface cable such
as the ALTINEX RC5201RS.
The cable must have the appropriate connector
on each end and the internal wiring must be
correct. Connectors typically have 9 pins (DB-9)
or 25 pins (DB-25).
Figure 1 shows the typical pinout and
connections for a DB-9 computer serial port and
Figure 2 shows the typical pinout and
connections required for a DB-25 computer
serial port.

7.4 RS-232 PROTOCOL
The RS-232 protocol for the MT101-114/115/117
uses a simple ASCII character format.
1. Brackets “[ ]” are part of the command
for the controller or plug-in card.
2. Brackets "{ }" are part of the command
for the panel display commands.
3. Use uppercase letters for all commands.
The MT101-114/115/117 have many advanced
remote control capabilities which are accessible
through standard RS-232 communication.
Control can be accomplished using a computer,
a control system, or any other device capable of
sending RS-232 commands. The factory
settings for the RS-232 port are as follows:
Baud Rate = 9600
Data Bits = 8
Stop Bits = 1
Parity = None
The enclosure and cards in a MultiTasker are
capable of performing various functions, as well
as providing feedback to the user or control
system. Commands instruct a card to perform
specific actions, request status information, and
some do both simultaneously.

A command that does not request specific
information will generate feedback of “[ ]”. The
open bracket immediately followed by a closed
bracket indicates the card or unit received a
valid command. If the command requested
information from the card or enclosure, the
feedback generated is the acknowledgement of
having received a valid command. Invalid
commands generate feedback that includes
“ERR” plus an error code.
Example: [ERR001]
Commands ending in “S” will be saved into
memory. Commands not ending in “S” will still
be executed, but will not be restored when the
system is reset or powered-off, then on.

MULTITASKER
7.4.1 DESCRIPTION OF COMMANDS
Each command can consist of up to three parts:
Function, Card/Group, and Unit. Card
commands require the card/group ID, whereas
enclosure commands do not.
[ Function , Card/Group ID , Unit ID ]
Example: [VERC3U2]
VER = Function
C3 = Card ID or Group ID
U2 = Unit ID (optional for Unit ID 0)
The card ID is a unique identifier. It is equal to
the enclosure slot number, or it may be an
assigned value. The group ID represents a
group of cards defined with the [WR] command.
All cards in a group perform the given
instruction.
NOTE: Changing the position of a card will
significantly affect control programs and
third-party control systems.
The unit ID may range from U0 to U20 where U0
is used for single-unit operation. If the ID is U0,
each command may be used without the unit ID.
See the command [SET] for details.
Example:
SYSTEM COMMANDS
System commands provide information about the
front panel, control feedback, and allow unit IDs to
be changed or identified.
1. [VER]
This command displays the current version of
the firmware for the controller unit located in the
MT101-114/115/117.
Command Format: [VERUi]
Ui = Unit ID (i = # from 0 to 20)
Example:
Query U1 for the installed firmware version.
Send the command [VERU1] to the enclosure
and the unit will return feedback similar to the
following:
[MT101-115 690-0122-030 690-0123-007
690-0124-027]
MT101-115: Front panel model number
690-0122-030: Control firmware version
690-0123-007: Process firmware version
690-0124-027: Panel firmware version
2. [SET]
[VERC3]: For U0
[VERC3Ui]: For U1-U20
[VERC3]: Equivalent to [VERC3U0]
7.5 RS-232 COMMANDS
See the COMMAND SUMMARY (section 7.6) for a
one-line description of each command. The RS-232
available commands in this section are organized
into the following groups:
System Commands
Group Commands
Configuration Commands
Special Commands
LED Commands
Key Commands
Subroutine Commands
400-0402-003
This command sets the ID number of a front
panel and may be directed to any unit
connected to the RS-232 bus.
Command Format: [SETUxUi]
Ux = New unit ID (x = # from 0 to 20)
Ui = Current unit ID (i = # from 0 to 20, optional)
Example 1: ID U0
Assign U0 to a single MT101-115 by sending
the command [SETU0]. After the command is
executed, the ID will be changed to U0 and the
system will return the following feedback:
Unit ID = 0
[ ]
READY

MULTITASKER
3. [RES]
The [RES] command resets the enclosure. The
controller and all cards in the enclosure will be
reset to either their default or saved
configurations.
Units with IDs U0 and U1 will beep once and
display "READY" after their initialization is
complete and all the functions stored in SUB1
have been executed. This will let the user know
that the unit is ready for operation. Units with
other IDs will beep once , but will not display any
feedback.
4. [?]
This command displays general information
about the MultiTasker and the cards installed.
Command Format: [?]
Example:
A MultiTasker has a front panel with part
number MT101-115 and contains an
MT103-121, MT103-122, and MT103-123. Send
[?] and receive the following feedback:
All status feedback is enclosed in brackets, “[ ].”
Each data field within the status is enclosed in
parentheses. The first two characters identify
the status type. The last three characters are the
card’s ID.
MT103-121 = Card model number
VR690-0197-005 = Firmware version
ON = Output is enabled
EQ10 = Equalization is set to 10
SI1 = Signal detect (1=yes)
6. [DFB]
This command disables all feedback from one or
all MultiTasker units connected together on a
single bus; it is designed for use with 19 and 20
slot MultiTasker enclosures.
7. [EFB]
This command enables feedback from one
MultiTasker unit only and disables feedback
from all other units connected on the bus; it is

CONFIGURATION COMMANDS
These commands allow some basic communication
properties to be changed as well as access to
internal processor functions like BEEP and PING.
Use caution when changing RATE and BAUD
settings as changes may result in unforeseen
problems.
16. [RATE]
This command displays the communication rate
between the MT101-114/115/117 and the cards
in the system. Each command that is stored in a
subroutine will be sent out to the cards at the
defined rate. Only skilled programmers should
use this command.
Command Format: [RATE]
Example:
Check the communication rate by sending the
command [RATE] and receiving feedback
similar to the following:
RATE=0(0ms)
17. [RATE=]
This command sets the communication rate
between the MT101-114/115/117 and the cards
in the system. If more than one command is
stored in a subroutine, each command will be
sent out at the defined rate. Increasing the rate
effectively adds a delay between each
command stored in a subroutine. Only skilled
programmers should use this command.
Command Format: [RATE=n]
n = rate, x100msec (n= # from 0-20)
Example:
Set the communication rate to 0 by sending the
command [RATE=0] and receiving feedback
similar to the following:
18. [RATE=S]
This command is the same as the [RATE=]
command but it also saves the communication
rate to memory. This saved rate will be restored
after power-up or reset. Only skilled
programmers should use this command.
Command Format: [RATE=nS]
n = rate, x100msec (n= # from 0-20)
19. [BEEPn]
This command sounds the front panel’s internal
buzzer for a specified duration.
Command Format: [BEEPn]

LED COMMANDS
LED commands apply to the MT101-115/117 only
and are used to control the LED states and retrieve
matrix settings based upon key entries. The LED
states (on, off, flashing) may be controlled directly
over the RS-232 bus or through the use of
subroutines programmed into the front panel.
30. {LEDn=}
This command activates a single key’s LED or
all LEDs.
Command Format: {LEDn=s}
n = # from 1 to 36 for a single LED
= * for all LEDs
s = # from 0 to 2
= 0 for OFF
= 1 for ON
= 2 for FLASH
Examples:
Command LED# Results
{ LED36=2 } 36 FLASH
Examples:
Command LED# Results
{ LED1-10=1 } 1 to 10 ON
{ LED13-36=0 } 13 to 36 OFF
32. {CLFC}
This command is a debug tool that clears the
memory of input-to-output connections used to
flash the LEDs for a single matrix card. This
command is used in conjunction with the {STA}
command.
Command Format: {CLFCn}
Cn = card number (n is # from 1 to max slots)
Example:
Key 2 on the front panel is programmed with the
{STA} command. See the {STA} command for
details.
A user connects Input 1 to Outputs 1, 2, and 3
on C2 from the front panel. The connection is
verified by pressing Key 2 and then the Input 1
key. The LEDs for Input 1 and Outputs 1, 2, and
3 all flash.
{ LED10=1 } 10 ON
{ LED*=0 } ALL OFF
{ LED*=1 } ALL ON
{ LED*=2 } ALL FLASH
31. {LEDm-n}
This command activates the LEDs for a
sequential range of keys.
Command Format: {LEDm-n=s}
m,n= # - ## for a sequential range from 1 to 36
= * for all LEDs
s = # from 0 to 2
= 0 for OFF
= 1 for ON
= 2 for FLASH
400-0402-003
Later, another user connects Input 8 to outputs
1, 2, and 3 over the RS-232 bus. The original
user begins experiencing problems and checks
the status from the front panel using Key 2.
None of the LEDs will flash. This indicates there
has been a change in the setup.
NOTE: If the {CLF} command is not used, the
front panel LEDs will continue to indicate the last
setup made using the front panel. Any changes
over the RS-232 bus will be not be indicated.
The user controlling the MultiTasker from the
RS-232 bus must send the command {CLFC2}
to clear the status LED information.
33. {CLFG}
This command is the same as the {CLFC}
command except that it clears the memory of
input-to-output connections used to flash the
LEDs for a group of matrix cards.
16
MULTITASKER
Command Format: {CLFGk}
Gk = Group number (k = # from 1-8)
See the {CLFC} command for details.
34. {STA}
This command is used to show the
input-to-output connections for Matrix
cards/groups as set from the front panel only.
The LEDs on the front panel flash to show
connections.
The {STA} command must be programmed into
a subroutine for the front panel.
NOTE: This command is used in conjunction
with the {CLF} command.
Command Format: {WRSy=LED*=0,STA}
Sy = subroutine (n is a # from 1 to 180)
Example:
C4 is an 8X8 matrix card and the following is
programmed into the front panel:
• Keys 13-20 select inputs for C4.
• Keys 29-36 select outputs for C4.
• Sub 2 contains the following:
{WRS2=LED*=0,STA}.
• Key 2 is programmed as follows:
{WRK2=2,0,0,0,0}.
Connect Input 1 to Outputs 1 and 2 on C4 and
verify the connection. Use the following steps:
NOTE: An input or output key can be selected
to see its connections. In either case, all
connections would be indicated. Selecting an
input key will show all the outputs to which the
input is connected. An output key will show only
the one input to which it is connected.
KEY COMMANDS
Key commands define which subroutines will be
performed when a key is pressed under various
conditions and how it will respond to activation.
Keys may also be given labels to help identify their
usage.
35. {RDK}
This command displays the contents of one or
more key programs. The subroutines defined
will be displayed first, then the key label, if any.
Next, if the key is defined as volume control, the
word VOLUME will be displayed. Lastly, if the
key is locked, the word LOCKED will be
displayed.
Command Format: {RDKn}
Kn = key program (n = # of key program)
{RDKn}: Display a single key program.
{RDK*}: Display all key programs.
Example 1:
Display the program definition for Key 1 by
sending {RDK1} and the system will display the
program in the following format:
1. From the front panel, connect Input 1
(Key 13) to Output 1 (Key 29). LEDs 13 and
29 flash.
2. Next, connect Input 1 (Key 13) to Output 2
(Key 30). LEDs 13 and 30 flash.
3. Press any key and the LEDs stop flashing.
4. Press Key 2 and then Key 13. LEDs 13, 29,
and 30 flash indicating Input 1 is connected
to Outputs 1 and 2.

Example 3:
Display the contents of all the keys by sending
{RDK*} and the system will display the key
programs in the following format:
KEY 01: 000,000,000,000,000 LOCKED
KEY 02: 000,000,000,000,000 VOLUME
KEY 03: 000,000,000,000,000 VCR_ON
KEY 04: 000,000,000,000,000 VCR_OFF
KEY 05: 000,000,000,000,000
KEY 06: 000,000,000,000,000
KEY 07: 000,000,000,000,000
…
KEY 34: 000,000,000,000,000
KEY 35: 000,000,000,000,000
KEY 36: 000,000,000,000,000
NOTE: Unlike the subroutines, all key programs
will be displayed even if they are not
programmed. Keys that have not been
programmed will be defined with all states equal
to zero (000,000,000,000,000).
State
Format: {WRKn=s1,s2,s3,s4,s5}
Kn = Key # (n = # from 1 to 36)
s1= Sub ID (#0 to 180) for state 1
s2= Sub ID (#0 to 180) for state 2
s3= Sub ID (#0 to 180) for state 3
s4= Sub ID (#0 to 180) for state 4
s5= Sub ID (#0 to 180) for state 5
NOTE: Use subroutine zero if nothing should
happen for a particular state. The key definition
{WRK2=2,0,0,0,0} tells the controller to execute
SUB2 if Key 2 is pressed when its LED is off
and nothing for the remaining states.
Example: Key 6
{WRK6=10,20,30,40,0}
What to do when a key is pressed
and…
1 the LED is OFF
2 the LED is ON
3 the LED is FLASHING
4 HELD for at least 2.5s
5 HELD for 2.5s at power -up
36. {WRK}
This command writes a key by assigning a
subroutine ID to each of the 5 key states.
CAUTION: If programming Key 1 to perform
functions from the front panel, remember SUB1
is a special case and is always performed on
power-up or reset. Use another subroutine
number, but make sure it can be recognized as
relating to Key 1. An example would be
SUB101.
A key may have up to five different states so it
can be assigned to execute five different
subroutines. The following table shows the state
number and the condition a key must be in for
the subroutine assigned to a particular state to
be executed.
400-0402-003
10 - State 1: Execute SUB10 when Key 6 is
pressed and LED6 is OFF.
20 - State 2: Execute SUB20 when Key 6 is
pressed and LED6 is ON.
30 - State 3: Execute SUB30 when Key 6 is
pressed and LED6 is FLASHING.
40 - State 4: Execute SUB40 when Key 6 is
PRESSED and HELD for 2.5s.
00 - State 5: Do nothing if Key 6 is PRESSED
and HELD for 2.5s on power-up.
NOTE: If there are any discrepancies or if the
buffer has not been initialized, the user will
receive a message such as PLEASE
PERFORM BUFFER TEST. Use the {TEST}
command to initialize the buffer. Please refer to
the {TEST} command for more information.

“OFFC5.” Send the command {RDSK2} and
receive the following feedback:
KEY 02: 002,020,021,000,000
SUB002: ONC5.........................
SUB020: OFFC5.........................
SUB021: EMPTY
NOTE: If a subroutine is assigned but not
programmed, it will be displayed as EMPTY.
T = Text string (15 characters max.)
Example:
Set Key 12's label to “CONF_RM_MON”
representing Conference Room Monitor. In
order to do this, send the command
{WRLK12=CONF_ROOM_MON}. Next, confirm
by sending the command {RDK12} and verifying
the feedback is as follows:
KEY 12: 012,000,000,000,000 CONF_RM_MON
400-0402-003
46. {SETVK}
This command defines a key as a volume
control key. It is used with audio cards that
support the Volume Ramp Up/Down features
such as the MT109-100. As volume control, only
the first two states are recognized in the key
program. The first sub is performed when the
key is pressed down and the second is
performed when the key is released. Keys
defined as volume will have the word VOLUME
displayed when using the command {RDK}.

MULTITASKER
Command Format: {SETVKn}
Kn = Key # (n = # from 1 to 36)
Example:
C2 is an MT109-100 and Key 8 is programmed
{WRK8=8,108,0,0,0}. SUB8 = “RUPC2” and
SUB108 = “RSTC2.” Pressing Key 8 begins
ramping up the MT109-100’s output volume.
Releasing Key 8 stops the ramping.
47. {CLRVK}
This command resets a key to normal function.
Command Format: {CLRVKn}
Kn = Key # (n = # from 1 to 36)
Example:
Change Key 8 in the previous example back to a
normal key by sending {CLRVK8}. Key 8 will
now support the normal 5 states of operation.
48. {UPLK}
This command uploads a key program from the
panel so it may be saved and edited as a text
file. The same file may be downloaded back into
the panel. Sub numbers and labels are saved,
but VOLUME and LOCKED settings are not.
Before uploading or downloading, the rate must
be set to the default zero, [RATE=0]. There is no
unit ID information in the key program. The key
program may be uploaded from any unit, for
example {UPLKU2}. However, when
downloading a key program all units connected
to the bus will receive the same key program.
There are two parts to the key program file. The
first contains the subroutine information and the
second the label information.
Command Format: {UPLK}
n = Key # (n = # from 1 to 36)
Example: Using HyperTerminal
Upload the key program file from the panel and
save it into a text file. Edit the text file using a
text editor and then download the new key
program into the control panel.
SETUP HYPERTERMINAL
Start a new connection in HyperTerminal as
“Direct to Com”. Make the following settings:
Bits per Second = 9600 baud
Date Bits = 8 bits
Parity = None
Stop Bits = 1
Flow Control = None
UPLOAD
1. Set the rate to zero, [RATE=0].
2. Click Transfer > Capture Text
3. Enter the file name (ex: MTKeys.txt).
NOTE: If the file already contains text,
HyperTerminal will append the file.
4. Click Start.
5. Send {UPLK} to upload the program.
6. Click Transfer > Capture Text > Stop.
EDIT
1. Use a text editor to modify the file
MTKeys.txt as saved above.
DOWNLOAD
1. Open the text file and select all the text.
SUBROUTINE:
Format: { $ , Key# , : , subroutines }
Example: { $ 0 1: 1 , 5 1 , 0 , 0 , 0 }
LABEL:
Format: { % , Key# , : , Label }
Example: { % 0 1 : VIDEO_CAMERA }
400-0402-003
2. Click Edit > Copy from the menu.
3. Select HyperTerminal.
4. Click Edit > Paste to Host.
5. Send the command {RDK*} and verify
modifications were saved.

MULTITASKER
SUBROUTINE COMMANDS
49. {RDS}
This command reads and displays the contents
of one or all subroutines.
Command Format: {RDSn}
n = Sub ID (n = # from 1 to 180, * for all)
Example 1: (Display one subroutine.)
Display the contents of SUB1 by sending
{RDS1} and the system will display the
subroutine number and its contents. The display
will be in the following format:
SUB001: LED*=0, LED1=1...............
OK
SUB001 = subroutine number
LED*=0, LED1=1 = stored functions
OK = done
Example 2: (Display all subroutines.)
Display all the subroutines. Send the command
{RDS*} and the display will be in the following
format:
SUB001: ON1C2, OFFC3, LED36=1.........
SUB002: ON2C2, OFF3C3, LED2=1.........
SUB005: ON3C2, OFF6C3, LED3=0.........
OK
NOTE: Empty subroutines will NOT be
displayed. If all the subroutines are
empty, the following will be display ed:
ALL SUBROUTINES ARE EMPTY
50. {WRS}
This command appends functions to a
subroutine. The subroutine contents may be
cleared using the {CLRS} command. The
command length is limited only by available
memory, but no more than 30 characters should
be sent in a single write statement.
Subroutines for front panel control most often
perform actions when a key is pressed. It is a
good programming practice to make the
subroutine number relate to the key number.
For example, Key 12 is used to perform
functions stored in subroutines 12 or 112
depending on the state the key. The control may
be passed to SUB12 if the key is pressed when
the LED is off and the control will be passed to
SUB112 if the key is pressed when the LED is
flashing.
Example:
Key # = SUB# ...........LED is OFF
= SUB#+50 .....LED is ON
= SUB#+100 ...LED is FLASHING
= SUB#+150 ...Key is Pressed & Held
Key 10= SUB10 .........LED is OFF
= SUB60 .........LED is ON
= SUB110 .......LED is FLASHING
= SUB160 .......Key is Pressed & Held
Key 10= {WRK10=10,60,110,160,0}
COMPLETE FUNCTIONS
Command Format: {WRSn=F1,F2,…}
Sn = Subroutine ID (n = # from 1 to 180)
F1,F2… = Functions must be separated by a
comma.
Example 1:
Program SUB1 with the following functions:
ON1C3, ON2C3, and LED1=1. Send the
following command :
{WRS1=ON1C3, ON2C3, LED1=1}
Add more functions such as ON3C3 and ON4C3
to the subroutine. Each write statement is
appended to the functions that are already
stored in the subroutine. Therefore, to add the
functions ON3C3 and ON4C3, it is only
necessary to send the following command:
400-0402-003
{WRS1=ON3C3, ON4C3}
22
MULTITASKER
After sending the command above, the contents
of Subroutine 1 will be as follows:
ON1C3, ON2C3, LED1=1,ON3C3, ON4C3
MATRIX FUNCTIONS
Command Format: {WRSn=&…&}
Sn = Subroutine ID (n = # from 1 to 180)
& = Continuity of the function
NOTE: The "&" is NOT needed at the
beginning or end of a function
definition, and should NOT be used.
WARNING: No other functions may be defined
while building a function using multiple keys.
Once the controller encounters an "&", it will join
the function pieces together until an
end-of-function is encountered. For example,
{WRS12=I1&,OFF1C4} would turn off Output 1
of C4, but the beginning of the matrix command
would no longer be valid. Likewise, the following
would NOT work for matrix functions:
{WRS22=&O1&,ON1C2} or
Matrix Functions, Example 2:
Split the function for I1O2C3 into three different
subroutines, S13, S30, and S11. Use the
following commands:
{WRS13=I1&}
{WRS30=&O2&}
{WRS11=&C3}
Press 3 keys to execute the function. The first
key pressed should be assigned to SUB13, the
second to SUB30 and the third to SUB11. The
command will build as follows:
I1& + &02& + &C3 = I1O2C3
The "&" informs the controller that the function
pieces are to be joined together. When joined
together, the function pieces must define a legal
command or the function will be ignored.
NOTE: Once again, if any other commands are
issued anytime before a legal command is
completed, the matrix command in process will
be destroyed and ignored.
{WRS32=LED1=1,&C4}
Matrix Functions, Example 1:
Split the function for I1O2C3 into 2 different
subroutines, SUB13 and SUB30. Use the
following commands to connect Input 1 to
Output 2 on C3:
{WRS13=I1&} and {WRS30=&O2C3}.
Press two keys to execute the function. First
press Key 13 for SUB13 and then Key 30 for
SUB30. The command will build as follows:
I1& + &02C3 = I1O2C3
The "&" informs the controller that the function
pieces are to be joined together. When joined
together, the function pieces must define a legal
command or the function will be ignored.
51. {WRS=S}
This command allows a subroutine to call the
functions stored in other subroutines instead of
writing the functions to the subroutine.
Command Format: {WRSn=S1,S2...}
n = Sub ID (n = # from 1 to 180)
S1,S2... = Sub no. (reference up to 10 subs)
Example:
Set SUB100 to execute subroutines 10, 20, 30,
40, and 50 by sending the command
{WRS100=S10,S20,S30,S40,S50}. When
SUB100 is executed, all the functions stored in
subroutines 10, 20, 30, 40, and 50 will be
executed.
400-0402-003
23
MULTITASKER
52. {PING}
This command displays “OK”, but not until after
is has been processed through the incoming
memory buffer. After downloading a program file
to the MultiTasker, this command can be used
to indicate when the MultiTasker has finished
writing everything to memory. This is only
necessary if the auto-feedback, “[ ]”, is disabled
using the [DFB] command.
Command Format: {PING}
Example:
The command {PING} instructs the MultiTasker
to display “OK.”
53. {SUB}
This command executes a subroutine through
RS-232 control.
Command Format: {SUBn}
n = Sub ID (n = # from 1 to 180)
Example:
The command {SUB10} executes the functions
stored in SUB10.
54. {CLRS}
This command clears one or all subroutines.
Command Format: {CLRSn}
n = Sub ID (n = # from 1 to 180, * for all)
Example:
55. {TEST}
This command performs a destructive test of the
memory buffer, keys, and LEDs. All subs will be
erased during this test.
Command Format: {TEST}
Example:
The command {TEST} tests the front panel and
will display a notification when started, followed
by a progress indicator, and finally a completion
notice as follows:
1) MEMORY BUFFER TEST: (TIME=90 SECONDS)
0%........25%.........50%.........75%........100%
BUFFER TEST: PASSED
After the results are displayed, the system will
prompt the user for the KEY/LED test:
2) KEY-LED TEST: PRESS A KEY TO TURN ON
ITS LED – TO EXIT: SEND RES OR TURN OFF
THE UNIT
Test each key by pressing it once. As each key
is pressed, its LED should turn ON and the
previous LED should turn OFF. If any of the
keys or LEDs do not behave as just described,
the key or its LED is bad. To exit this test, turn
the system off, and then back on again.
56. {WAIT}
This command instructs the controller to delay
or pause before the next command is executed.
Clear SUB80 by sending the command
{CLRS80}.
NOTE: The system will display a warning when
the {CLRS*} command begins. This will be
followed by periods indicating progress until the
final message is displayed as follows:
PLEASE WAIT 20 SECONDS....................
SUBROUTINES ARE CLEARED
400-0402-003
Command Format: {WAITn}
n = delay time (1=100ms, 2=200ms…)
Example:
Sent the command {WAIT2} to cause a delay of
200ms in the controller.

7.7 CONTROL SOFTWARE
Windows-(95/98/NT)-based control software is
available from the ALTINEX website at
www.altinex.com in the Software section.
7.8 MENU MODE
Menu Mode commands allow virtually the same
functionality as programming commands. Unlike
the programming commands in the previous
sections, menu commands prompt the user to
select from a list of available options. The system
then responds based upon user selections.
7.8.1 MENU COMMAND DEFINITIONS
Each type of MultiTasker card has unique menu
functions and capabilities. The commands
accessed in Menu Mode vary depending on the
card type. See each individual User ’s Guide for
available functions and detailed instructions.
7.8.2 USING MENU MODE
Do NOT press any keys except those relating to
the current menu. If you press the ENTER key
after entering a letter or digit, the original list of
systems will be displayed.
1. In order to enter Menu Mode, the system
needs to be connected to a computer
running RS-232 control software.
2. In the Terminal W indow, press the ENTER
key on the keyboard.
3. The system displays a list of available
MultiTaskers.
6. Enter the 2-digit ID and a menu for the card
will be displayed. In the example above,
enter “04” for the MT104-130.
7. The system will prompt for selections
specific to the selected card.
8. Read each menu carefully, and continue
selecting keys as prompted.
7.8.3 MENU TYPES
1. MAIN MENU
The first menu displayed after selecting the
card is the Main Menu. This menu provides
access to the key functions related to the
card. Press the key representing the menu
item for access and a sub-menu will appear.
2. SUB-MENUS
Each menu item will display either a
sub-menu, or a list of options. Press the key
corresponding to the desired choice.
TROUBLESHOOTING GUIDE 8
We have carefully tested and have found no
problems in the supplied MT101-114/115/117;
however, we would like to offer suggestions for the
following:
8.1 CARD IS NOT WORKING
Cause 1: The card cage is not plugged in.
Solution: Plug in the card cage in. If the card
works, the problem is solved. If the
card still does not work, see
Cause 2.
Example: 1: U1
2: U2
3: U3
4. Enter the ID number of the desired system.
In the example above, enter a “1” for the
MultiTasker with unit ID 1.
5. The system then interrogates all the cards
in its enclosure and then lists the cards.
Example: 01: MT103-122
02: MT103-123
04: MT104-130
400-0402-003
Cause 2: The card cage slot has a problem.
Solution 1: Test the card in other slots of the
card cage. If the slot was damaged,
the card may work in other slots. If
other slots work, the problem is the
card cage slot. The card cage may
require service. Call ALTINEX at
(714) 990-2300. If the other slots do
not work, see Solution 2.
26
MULTITASKER
Solution 2: Take any other known good card
and verify the questionable slot is
good by seeing if its LED lights in
that slot. If it lights, then the original
card may be the source of the
problem. Call ALTINEX at
(714) 990-2300. If the original card
was not the source of the problem,
see Cause 3.
Cause 3: The input power voltage is incorrect.
Solution: Make sure that the input power
range is within 85-264 VAC and also
make sure that the power is
connected to the input power
connector. If there is still a problem,
call ALTINEX at (714) 990-2300.
