REVISION NOTES V1.31 1. Delete the query commands of Toggle and Standby 2. Add query command of MUT for feeding back the information of Mute or Un-Mute. V1.32 1. TUNER (STX)KEY:16(ETX) response “ER” when there is no TUNER 2. PREVIOUS CHANNEL (STX)KEY:35(ETX) response “ER” when there is no TUNER 3. CHANNEL COMMAND returns “ER” if there is no TUNER 4. The range of TINT is from -25 to +25, therefore we should revise the range of TIN:xxx to 00~50 5. The range of AUTO COLOR is from 0 - 1, we should revise the range accordingly 6. There is only WARM, NORMAL and COOL color temperature in our Monitor, we should revise the range to 0 ~2. V1.33 1. Added STX and ETX syntax description for TV response to control system queries. 2. Added notes regarding query responses on sets without tuners 3. Added note regarding baud rates for K and R chassis 4. Added query command for Auto Color Control and Color Temp V1.33a 1. Corrections on query responses for CON, BRT, SAT, TIN, ACC, TEM 2. Addition of “ER” response for ZOOM2 command on R chassis 3. Cleaned up formatting of document 4. Corrected MTS response V2.0 1. Added commands for Tuner2 and HDMI3 2. Added “INVALID” response for unsupported features/inputs 3. Removed hex strings from Examples for clarity (Page 5) V2.01 1. Modified document syntax for hex strings for clarity.

V2.02 1. Added S-Video2 INP command. 2. Modified Color Temperature (TEM) syntax V2.03 Added caution notes about non-standard DB-9 configuration V3.0 Added commands for FX5series, additional remote IR equivalents, NuCard inputs, headphone volume, overscan, FX5 NuControl port pinout & diagram. V3.1 Added commands for additional HDMI inputs for 65” V3.2 Modified RS-232 baud rate for 65” to 19.2 KBPS V3.3 Added INP command for NuCard S-Video input, modified RS-232 baud rate for 65” to 9600 KBPS V3.4 Added Baud rates for new models V3.6 Modified RJ45 diagram V3.7 Added RS-232 commands for 3D/2D modes V3.8 Added Frame Packing 3D commands Added Pixel and Line Interleave commands for VGA input Added Backlight commands

Physical Definition: NVUxxL and NVUxxDCM series: The interface connector on the TV is a standard 9 pin D-sub connector used on most computers. The jack type is a female chassis mount connector. NOTE: The pinout configuration is not a standard RS-232 configuration. When using RS-232, ONLY connect pins 2, 3 and 5. When using IR, ONLY connect the required pins. Female D-sub 9pin: 1. IR in WITH carrier 2. TXD (FROM the TV) 3. RXD (TO the TV) 4. Remote IR IN NO carrier (0-5 volts) 5. Ground 6. Remote IR Out NO carrier (0-5 Volts) 7. Remote IR Out WITH Carrier (0-5 Volts) 8. N/C 9. 5 Volt DC@100 mA out (from TV)

6

NVUxxFX5 Series: NOTE This connector is not an Ethernet connection. Do not connect this port to an Ethernet connection, damage can occur to the TV and the Ethernet port. Female RJ45

1. IR IN with carrier 2. RS-232 TXD (From TV) 3. RS-232 RXD (To TV) 4. IR IN no carrier 5. GND 6. IR OUT no carrier 7. IR OUT with carrier 8. +5VDC @100mA out (From TV)

Basic Format for Control: The Transmission of data from the Controller (Computer or AV Controller) starts with an STX [02h] signal, followed by the command, then the parameters, and lastly an ETX [03h]signal. If there are no parameters, then the parameter does not need to be sent. A colon separates the commands from the parameters. All Commands start with STX [02h] and end with ETX [03h]. Any data not contained between the STX and ETX commands will be ignored by the TV. STX and ETX must be sent as hex commands; all other data must be sent as ASCII characters. NOTE: The brackets [ ] in the rest of this document do not get sent or returned in the command/query. They are there to indicate characters to be sent in hex. All responses from the TV to Queries start with STX [02h] and end with ETX [03h]. Any data not contained between the STX and ETX commands must be ignored by the controller. STX and ETX will be sent as hex commands; all other data will be sent as ASCII characters. Optional ID number: Three ASCII digits ranging from 000-999. Each TV will have the option in the Factory Menu of setting a Unit ID Number. A Semicolon (;) separates the ID Number from the Command. The ID number may be set on the TV in the Service Menu. Contact NuVision Customer Service for instructions on accessing the Service Menu at 800-605-8022 or techsupport@nuvision.com Each command is a string of ASCII characters plus a Parameter A colon separates the Command from the Parameter. The Parameter is 1 to 5 ASCII characters long. After each command is received, the TV shall send back an acknowledgment. For most commands, this will be a simple STX[02h] , the ASCII letters “OK”, and an ETX[03h]

10

If there is an error, the TV shall return STX, the ASCII letters “ER”, and ETX. There may be parameters added after a colon if more details are possible. If a command is sent to a TV that does not support this command, i.e. a tuner command for a monitor, the set shall return STX, the ASCII letters “INVALID” and ETX. NOTE: AMX programmers may need to add 100ms delays between parameters in commands. Examples: All commands are ASCII, except STX and ETX, which must be sent in hex. NOTE: The brackets [ ] in the rest of this document do not get sent or returned in the command/query. They are there to indicate characters to be sent in hexadecimal form. Example of a Power ON for Unit 001: COMMAND: [02h]001;KEY:100[03h] TV Returns: [02h]OK[03h]

Example of a Power ON with No Unit Number: COMMAND: [02h]KEY:100[03h] TV Returns: [02h]OK[03h]

Query Examples: Use a “?” as the parameter and the TV will return the current value for that command. There is no “OK” returned after a query. Example of a Power Query with no Unit Number.

[02h]PWD:?[03h]

Would return this status if the TV is ON: [02h]1[03h]

Or, this status if the TV is OFF: [02h]0[03h]

11

Example of a Volume Query with No Unit Number, assumes that the Volume is set at 50.

[02h]VOL:?[03h]

TV Returns: [02h]50[03h] Query only works with the Following Commands Power PWD Channel CHA Input INP Volume VOL Contrast CON Brightness BRT Color Saturation SAT Tint TIN Mute MUT Auto Color Control ACC Color Temp TEM 3D Status DIM KEY COMMANDS: These commands are the equivalent of sending the IR code from the remote control.
