About Your MT115-111 The MT115-111 provides a means of receiving computer or component video and audio signals over Twisted Pair-type (CAT-5) cable when used together with an ALTINEX Twisted Pair Video Transmitter, such as the MT115-110 or TP115-110. The MT115-111 offers two 15-pin HD female outputs and two 3.5 mm audio outputs, one for each of the inputs. The RJ-45 inputs receive the differential video and audio signals generated by the Twisted Pair transmitter. The MT115-111 also offers video equalization for long cable lengths. The equalization adjustment may be set for either hardware or software (RS-232) control. Additionally, the MT115-111 offers the option for video gain adjustments through RS-232 control or the gain may be set to a value of one for hardware control. As an added feature, the MT115-111 offers the option of selecting a Sync-on-Green (SOG) output. The SOG feature is a simple switch setting that may be set for SOG or standard RGBHV. The latest generation of Twisted Pair devices uses an innovative, patented technology* developed by ALTINEX. The new signal processing technology allows transmitting and receiving fully equalized computer video signals, stereo, and audio signals over long distances * US Patent 7,065,190 400-0443-005 3 MT115MT115-111 User’s Guide 6.

Operation 7.1 RS-232 Control Changing the position of a card will significantly affect the commands recorded on software definitions or third-party control systems. The MT115-111 has many advanced remote control capabilities accessible through standard RS-232 communication. Control may be accomplished through a computer, control system, or any device capable of RS-232 communication. The unit ID has a range from U0 to U20. U0 should be used for single unit operation. If the ID is set to U0, each command may be used without Ui. Use the command [SETU0], as explained in the MT101-101 User’s Guide. 7.1.1 RS-232 Interface Example: The control commands for the MT115-111 are in a simple ASCII character format. 1. 2. 3. Square brackets "[ ]" are part of the command. Use uppercase letters for all commands. Spaces are not legal characters. For U0 [VERC3Ui]: For ID other than U0 [VERC3]: Equivalent to [VERC3U0]. Command Organization The RS-232 commands in this section are organized into the following 5 categories: The 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 or request information from the card. Some commands do both simultaneously. Basic Commands Feedback Control A command that instructs the card only to perform an action will generate feedback of "[ ]". The open bracket immediately followed by a closed bracket indicates the card received a valid command. If the command requested information from the card, the feedback generated by the card is the acknowledgement of having received a valid command. Invalid commands generate feedback that includes "ERR" plus an error code. Example 1: [ERR001] Example 2: [ERRC04] [VERC3]: Card Control Card IDs Groups See the Summary of Commands (Section 7.3) for one line descriptions of each command. Error number Card error C4 Basic Commands The basic commands are used to provide general information about the card. These commands are most useful during the initial stages of setting up and operating the card. 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. 1. [VER] 7.2 Description of Commands This command displays the software version and card type for the MT115-111 card. Each command consists of three parts: Function, Card ID, and Unit ID. [ Function , Card ID , Unit ID ] Command Format: [VERCn] Example: [VERC3U2] Cn = Card ID (n = slot # from 1 to max slots) VER = Function Example: C3 = Card ID or Group ID U2 = Unit ID (optional for Unit ID 0) An MT115-111 card is in slot 4. Send the command [VERC4], and the system will return feedback similar to the following: For Function, see a detailed explanation under each command description. [MT115-111 690-0231-001 C04] MT115-111 The card ID is a unique identifier. It is equal to the enclosure slot number, or it may be an assigned value. As the slot number, the value can range from 1-4 up to 1-20 depending on the enclosure. If the value is assigned, the ID may be a maximum of 99. Card ID 0 (C0) is used for the controller and cannot be reassigned. 690-0231-001 = Firmware version C04 The group ID is a number representing a group of cards defined with the [WR] command. When using the group ID, all cards in the group will perform the given instruction. NOTE: In this guide, cards are referenced by their IDs (C1, C2...C99). Typically, the ID number will be equivalent to the slot number. Groups will be referenced by their IDs (G1-G8). 400-0443-005 = Card model number 7 = Card ID MT115MT115-111 User’s Guide 2. [C] 6. [TEST] This command receives the status of the card. This command performs a series of tests on the internal memory and displays a pass message if successful. Otherwise, failures are indicated. Command Format: [Cn] Cn Command Format: [TESTCn] = Card ID (n = # from 1 to max slots) Cn Example: Upon completion, the system will display the results. This feedback will be similar to the following: There is one MT115-111 card in slot 4. Sending the command [C4] to the system will yield feedback similar to the following: MEMORY IC TEST RESULTS: MEMORY IC PASS INPUT#1 VIDEO GAIN 4 EQUALIZATION 32 INPUT#2 VIDEO GAIN 4 EQUALIZATION 32 7. [HELP] This command displays information available for the MultiTasker interface commands. In this case, both card inputs are set for a video gain of 4 and an equalization of 32. Command Format: [HELPCn] If there is no card in slot 4, sending the [C4] command will not return any feedback. Cn In order to display the RS-232 commands available for the MT115-111 card in slot 4, send the command [HELPC4]. The commands along with a brief description will be displayed in the Terminal Window. This command saves the card settings and displays the status. After the system is reset or powered off and on, the settings are restored. = card number S = save configuration = Card ID (n = # from 1 to max slots) Example: 3. [CnS] Cn = Card ID (n = slot # from 1 to max slots) Feedback Control The next commands are a function of both the card and the front panel and allow flexibility over when and how card information is displayed. Example: Save the status by sending [C4S]. The feedback returned will be similar to the following: 8. [FBD] INPUT#1 VIDEO GAIN 4 EQUALIZATION 32 INPUT#2 VIDEO GAIN 4 EQUALIZATION 32 This command turns feedback delay on or off. It is necessary when installing some newer cards in older systems. If the system does not receive all of the feedback from the card, the card may be communicating too fast. This command will slow down the card's communication rate. SAVED Command Format: [FBDm] 4. [...S] m This command will save the configuration command being sent in memory. When sending the command [EQ1=16C4S], after reset or power up, the equalization for Input 1 will be set to 16. Example: The command [HELPC4] is sent to the card in slot 4. Some of the HELP file is displayed on the screen, but most is missing. Send the command [FBD1] to slow down the rate at which the card sends feedback to the system. 5. [CLR] This command clears the card settings and returns it to the factory default values. The defaults gain setting is 4 and the default equalization setting is 32 for each input. Command Format: [CLRCn] Cn = Card ID (n = slot # from 1 to max slots) Example: In order to clear the card in slot 4, send the command [CLRC4]. The card will respond with the following feedback when complete: FACTORY RESET COMPLETED 400-0443-005 = Delay (0= no delay, 1= delay 100mS) 8 MT115MT115-111 User’s Guide 9. [?] Command Format: [STA1] This command will return general information about the MultiTasker and cards installed in the unit. Feedback Prefix Definitions: MT Card Model Number Command Format: [?Ui] Ui VR Firmware Revision = Unit ID (i = from 0 to 9) GN Video Gain Levels Example: EQ Equalization Levels A MultiTasker with unit ID 1 has a front panel with part number MT101-101 and contains an MT103-122 and MT115-111. Send the command [?U1] and receive the following: Example: Command = [EQ1=1C4] [(MT101-101U1)(MT103-122C01)(MT115-111C04)] Feedback = (EQ0132C04) EQ = Equalization 01 = Input 1 Equalization 32 = Input 2 Equalization C04 = Card ID MT101-101U1 = Panel number/unit ID MT103-122C01 = MT103-122 is in slot 1 MT115-111C04 = MT115-111 is in slot 4 10. [?C] This command will return general information about the card and its status. 12. [STA0] Command Format: [?Cn] Cn This command disables automatic feedback from the card and front panel. The command affects all cards with auto feedback capability, not just the MT115-111. The default at power on or reset is STA0, OFF. = Card ID (n = # from 1 to max slots) Example: The MT115-111 in slot 4 has Inputs 1 and 2 set to their default values. Send the command [?C4] to receive feedback similar to the following. Command Format: [STA0] Card Control [(MT115-111C04) (VR690-0231-001C04) (GN0404C04) (EQ3232C04)] Card control commands allow the main functions of the card to be executed over the RS-232 bus, or from the front panel’s programmable keys. All feedback is enclosed in square brackets. Each data field in the status is in parentheses. The first two characters identify the status type and the last three are the card’s ID. 13. [EQ] MT115-111 = Card model number VR690-0231-001 = Firmware version This command displays the equalization setting for an input and selects that input for adjustment using the [+] and [-] commands. GN0404 = Video gain levels Command Format: [EQmCn] EQ3232 = Equalization settings m = Input # (m = 1 or 2) The video gain levels are displayed for both Input 1 and Input 2. The first 2 digits are the setting for Input 1 and the last 2 digits are the setting for Input 2. In this case, both are set to a level of 4 out of 11. Cn = Card ID (n = slot # from 1 to max slots) The equalization levels are displayed for both Input 1 and Input 2 as well. The first 2 digits are the setting for Input 1 and the last 2 digits are the setting for Input 2. In this case, both are set to a level of 32 out of 64. Display the equalization setting for Input 1 of C4, then increase the equalization level by 3 from a starting value of 12. Example: Send the command [EQ1C4] and the current setting for Input 1 will be displayed. 11. [STA1]  This command enables automatic feedback from the front panel. The command affects any card with auto feedback capability, not just the MT115-111. The power on default or reset is STA0, off. For more details, see the [?Cn] command definition. 400-0443-005 Next, send the commands [+], [+], and [+] to increase the setting by 3. Send the [EQ] command again to receive new value.  9 MT115MT115-111 User’s Guide 14. [EQ=] ID Commands This command sets the equalization for an input to a value specified by the user. The default card ID is the same as the card slot number. The next several commands allow the user to change the card ID to a value other than the slot number. Once the ID is changed, moving the card to another slot will not change the card ID. If a card in slot 4 is set to ID 1, then moved to slot 10, its ID will remain 1. The [RSI] command forces each installed card to take its slot number as its ID number, regardless of the slot in which it is installed. Command Format: [EQm=xCn] m = Input # (m = 1 or 2) x = Equalization level (m = # from 1 to 64) Cn = Card ID (n = slot # from 1 to max slots) Some cards require more than one slot in the MultiTasker system. As an example, some matrix switcher cards require 4 slots. If 5 of these cards are installed, they would be numbered C4, C8, C12, C16, and C20. Changing the ID allows the user to define the cards as C1, C2, C3, C4, and C5. Example: Set the equalization on Input 2 of C4 to a value of 32 by sending the command [EQ2=32C4]. The card will respond with feedback of "[ ]" once the command is executed. Another use for changing the card ID is to be able to use multiple systems without having to set each unit to a different unit ID. All systems may be left as unit ID 0 for ease of programming. The cards in the first unit may be numbered 1-10 and in the second unit 11-20. 15. [GAIN] This command displays the gain setting for an input and selects that input for adjustment using the [+] and [-] commands. A gain setting of 4 is equivalent to unity gain. 17. [RSI] This command resets the card IDs in the system. After sending this command, each card ID in the system will match the slot number of the card. If the card is moved to another slot, its ID number will be the new slot number. Command Format: [GAINmCn] m = Input # (m = 1 or 2) Cn = Card ID (n = slot # from 1 to max slots) Command Format: [RSI] Example: Example: Display the gain setting for Input 2 of C4, then decrease the gain level by 3 from a starting value of 10. Send the command [RSI] to the system with Unit ID 0. The card in slot 1 will have ID 1, the card in slot 2 will have ID 2, and so on. If the card in slot 1 is then moved to slot 4, the card ID will then be 4. Send the command [GAIN2C4] and the current setting for Input 1 will be displayed.  18. [SIDn] Next, send the commands [-], [-], and [-] to decrease the setting by 3. Send the [GAIN] command again to receive new value. This command sets all the cards installed in the MultiTasker system to the same card ID. After sending this command, all cards will be addressed with the same ID. Use caution when sending this command to a system with multiple board types.  16. [GAIN=] This command sets the gain level for an input to a value specified by the user. A gain setting of 4 is equivalent to unity gain. Command Format: [SIDn] Command Format: [GAINm=xCn] Example: m = Input # (m = 1 or 2) x = Gain level (m = # from 1 to 11, 4 = unity) Send the command [SID1] to the system. All the cards in the system now have ID 1. Any commands that are sent to card ID 1 will be received and executed by each card. Cn = Card ID (n = slot # from 1 to max slots) n = Card ID (n = # from 1 to 99) 19. [SIDnCi] Example: This command sets the card ID of a single card to a number from 1 to 99. Set the gain level for Input 2 of C4 to a value of 4 by sending the command [GAIN2=4C4]. The card will respond with feedback of "[ ]" once the command is executed. Command Format: [SIDnCi] n = Card ID (n = # from 1 to 99) Ci = Slot Number (i = # from 1 to max slots) Example: Send the command [SID50C10] to set the ID of the card in slot 10 to an ID of 50. 400-0443-005 10 MT115MT115-111 User’s Guide 20. [SID+] Example: This command sets the card ID of all cards in a system to their slot number plus the offset value. Add C2, C4, and C6 to G5 by sending the command [WRC2C4C6G5]. After executing this command, G5 will consist of C2, C4, and C6. Command Format: [SID+n] Now add C8 to G5 by sending [WRC8G5]. C8 is added to G5, and G5 is not overwritten. View the contents of G5 by sending [RDG5] and receiving the following feedback: n = Offset amount (n = # from 0 to 99) The maximum card ID is 99, so subtract the highest slot number from 99 to find the maximum offset. For example, in an 8 slot enclosure, the maximum offset would be 91. The slot number (8) plus the offset (91) equals 99. [G5=C2C4C6C8] 23. [RMC] This command removes one or more cards from a group. Example: Command Format: [RMCn1Cn2…Gk] There are two 20-slot enclosures to be connected together during normal operation. The first unit will use the default IDs where the card ID is equal to the slot number. The second unit will have the same unit ID, but each card ID will be offset by 20. 24. [RMG] This command deletes one or all groups. This command displays the slot number of a card with a specified ID number. If more than one card has the same ID, each slot number will be displayed. Command Format: [RMGk] Gk Command Format: [RSNCi] Remove all cards from G52 by sending [RMG5]. The system will return the following feedback: Example: The card in slot 4 takes up four slots in the enclosure. Its ID was set to 1 since it is the first card installed in the system, reading from left to right. Send the command [RSNC1] to find the slot number of this card. The system responds with the following feedback: [G5=0] Example 2: Remove all cards from all groups, effectively deleting all groups, by sending [RMG*]. The system will return the following feedback:  G1-G8: EMPTY Group Commands 25. [RD] Group commands allow several cards with the same functions to be controlled simultaneously with a single command. Up to 8 groups (G1-G8) may be defined. These commands apply to all cards, not only the MT115-111. This command reads and then displays the members in a group. Command Format: [RDGk] Gk 22. [WR] C2, C4, and C6 make up G5. Read the member data for G5 by sending the command [RDG5]. The system will return feedback as follows: Group 1 = Video Cards Group 2 = Audio Cards Group 3 = Video and Audio Cards [G5=C2C4C6] The feedback shows G5 and then the cards that make up G5. In this case, G5 includes C2, C4, and C6. Command Format: [WRCn1Cn2…Gk] 400-0443-005 = Group ID (k = # from 1-8) Example: This command adds cards to a group. In MultiTasker systems with audio and video cards, the groups are typically as follows: = Group ID (k = # from 1-8) = Group ID (k = # from 1-8, * for all) Example: = Card ID (i = # from 1 to 99) Gk = Group ID (k = # from 1-8) [G5=C2C4] 21. [RSN] = Card ID (n = slot # from 1 to max slots) Gk G5 consists of C2, C4, C6, and C8. Remove C6 and C8 by sending [RMC6C8G5]. View the contents of G5 by sending [RDG5] and receiving the following feedback: The cards in the first unit will be referenced as card IDs 1-20 and the cards in the second unit will be referenced by card IDs 21-40. Cn = Card ID (n= # from 1 to max slots) Example: Connect the computer to the second unit only and send the command [SID+20] to set the ID of all the cards in the second enclosure to their slot number plus 20, then reconnect both units.
