MULTITASKER 7.2 MT101-114/115/117 OPERATION MATRIX KEY CONVENTIONS 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. The front panel is designed to use the center group of keys for Matrix card input and output selections. On the MT101-115/117, the front panel uses 36 programmable keys to control plug-in cards.
MULTITASKER 7.3 RS-232 CONNECTION 7.4 RS-232 PROTOCOL 7.3.1 RS-232 COMMUNICATION The RS-232 protocol for the MT101-114/115/117 uses a simple ASCII character format. 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.
MULTITASKER 7.4.1 DESCRIPTION OF COMMANDS SYSTEM 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. System commands provide information about the front panel, control feedback, and allow unit IDs to be changed or identified. 1. [VER] [ Function , Card/Group ID , Unit ID ] This command displays the current version of the firmware for the controller unit located in the MT101-114/115/117.
MULTITASKER 3. [RES] 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. The [RES] command resets the enclosure. The controller and all cards in the enclosure will be reset to either their default or saved configurations.
MULTITASKER 10. [STA1] 13. [RMC] This command enables automatic feedback from the cards installed in the system and affects any card with auto-feedback capability. The default at power-on or reset is STA0 or off. For more details, see the [?Cn] command definitions for individual cards. This command removes one or more cards from a group. Command Format [STA1]: = On Example: Command Format: [RMCn1Cn2…Gk] Cn = Card ID (n= # from 1 to max slots) Gk = Group ID (k = # from 1-8) 11.
MULTITASKER 18. [RATE=S] 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. 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. 16.
MULTITASKER 22. [BAUD] In order to change the baud rate, perform the following steps: This command displays the current BAUD rate setting. 1) Press & Hold both keys 5 simultaneously for 2.5 seconds. 2) LEDs 1, 2, 3, and 4 will turn on and one of the four will be flashing. The flashing LED represents the current baud rate setting. 3) Press & Hold for 2.5 seconds the key representing the desired baud rate. 4) After 2.5 seconds, all 4 LEDs will be extinguished. 5) The new baud rate is set.
MULTITASKER Example: Example: Send the text string "HELLO" to the RS-232 bus. The string will be ignored by the MultiTasker, but not the unit receiving the command. Additionallly, it will add opening and closing brackets. To do this, send the command [TXMHELLO] and the following will be sent to the RS-232 bus: Send the command string "abc[123]xyz" to the RS-232 bus. The string will be ignored by the MultiTasker, but not the unit receiving the command.
MULTITASKER Examples: 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. Command LED# Results { LED1-10=1 } 1 to 10 ON { LED13-36=0 } 13 to 36 OFF 32. {CLFC} 30.
MULTITASKER 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. 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.
MULTITASKER Example 2: State The Key 8 label is SPEAKERS; it is set for volume control, and it is unlocked. The system will return the following: 1 2 3 4 5 KEY8= 8,108,0,0,0 SPEAKERS VOLUME Example 3: Display the contents of all the keys by sending {RDK*} and the system will display the key programs in the following format: the LED is OFF the LED is ON the LED is FLASHING HELD for at least 2.5s HELD for 2.
MULTITASKER 37. {CLRK} Example 1: This command clears the subroutines associated with one or all the keys by setting each to 000. Other key settings remain unchanged: labels, volume control, and locked. The command {UNLK1} unlocks Key 1 only. No other keys are affected. NOTE: Use the {RDK} command to check the status of locked or unlocked keys. Command Format: {CLRKn} 40.
MULTITASKER 44. {CLRLK} Send the command {KFB=1} to enable key feedback. Press Key 1 and then press Key 36. The feedback will be as follows: This command is used to clear the key label for one key or for all keys. K01OS10 K36NS36 Command Format: {CLRLKn} NOTE: The keys do not have to be programmed in order to return feedback. If they are not programmed or there is no subroutine defined for the state when they are pressed, the subroutine number returned will be “0.
MULTITASKER Command Format: {SETVKn} Command Format: {UPLK} Kn = Key # (n = # from 1 to 36) n Example: Example: Using HyperTerminal 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. 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.
MULTITASKER 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. SUBROUTINE COMMANDS 49. {RDS} This command reads and displays the contents of one or all subroutines. For example, Key 12 is used to perform functions stored in subroutines 12 or 112 depending on the state the key.
MULTITASKER After sending the command above, the contents of Subroutine 1 will be as follows: Matrix Functions, Example 2: Split the function for I1O2C3 into three different subroutines, S13, S30, and S11. Use the following commands: ON1C3, ON2C3, LED1=1,ON3C3, ON4C3 MATRIX FUNCTIONS {WRS13=I1&} Command Format: {WRSn=&…&} {WRS30=&O2&} Sn = Subroutine ID (n = # from 1 to 180) & {WRS11=&C3} = Continuity of the function NOTE: Press 3 keys to execute the function.
MULTITASKER 52. {PING} 55. {TEST} 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. This command performs a destructive test of the memory buffer, keys, and LEDs. All subs will be erased during this test.

MULTITASKER 7.7 CONTROL SOFTWARE 6. Windows-(95/98/NT)-based control software is available from the ALTINEX website at www.altinex.com in the Software section. 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.
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.
