NXI NetLinx Integrated Controller NXI NetLinx Integrated Controller Overview The NXI NetLinx Integrated Controller represents the new generation of AMX multi-port central controllers. The NXI can be programmed to control RS-232/422/485, Relay, IR/Serial, and Input/Output devices using the NetLinx programming language and NetLinx Studio program. Depending on your specific control needs, the NXI can be equipped with either a Master or Hub Card.

Connections and Wiring Connections and Wiring Installing the Master or Hub Card The NXC-ME260 NetLinx Master or any Hub Card can be installed in the NXI. The card mounts in a horizontal position, through the master card slot on the rear panel of the NXI enclosure (see FIG. 3 on page 1). To install a Master or Hub Card in an NXI: 1. Discharge the static electricity from your body by touching a grounded metal object. 2. Unplug all the connectors from the NXI. 3.
Connections and Wiring IR/Serial Connections and Wiring You can connect up to eight IR- or serial-controllable devices to the IR/Serial connectors (ports 8-15). These connectors accept an IR emitter (CC-NIRC) that mounts on the device's IR window, or a mini-plug (CC-NSER) that connects to the device's control jack. The IR/Serial connector wiring specifications are listed in the following table. IR/Serial Connector Wiring Specifications No.
Programming Programming This section describes the Send_Commands, Send_Strings, and Channel commands you can use to program the NXI. The examples in this section require a declaration in the DEFINE_DEVICE section of your program to work correctly. Refer to the NetLinx Programming Language instruction manual for specifics about declarations and DEFINE_DEVICE information. Using the ID Button The ID Button on the rear panel of the NXI (FIG.
Programming Program Port Commands Command Description DATE Displays the current date and day of the week. DEVICE STATUS Displays a list of all active (on) channels for the specified D:P:S. Enter DEVICE STATUS without the D:P:S variable, the Master Card displays ports, channels, and version information. DNS LIST Displays: • Domain suffix • Configured DNS IP Information DOC FREE Displays the total bytes of free space available on the Master Card's Disk on Chip.
Programming Program Port Commands (Cont.) SET DATE Prompts you to enter the new date for the Master Card. When the date is set on the Master Card, the new date will be reflected on all devices in the system that have clocks (i.e. touch panels). By the same token, if you set the date on any system device, the new date will be reflected on the system’s Master, and all connected devices. This will not update clocks on devices connected to another Master (in Master-to-Master systems).
Programming ESC Pass Codes There are 'escape' codes in the pass mode. These codes can switch the display mode or exit pass mode. The following 'escape' codes are defined. Escape Pass Codes Command Description + + ESC ESC Exit Pass Mode: Typing a plus (shift =) followed by another plus followed by an ESC (the escape key) followed by another escape exits the pass mode. The Telnet session returns to "normal".
Programming LED Disable/Enable Send_Commands The following commands enable or disable the LEDs on the NXI. LED Send_Commands LED-DIS Disables the LEDs. Issue this command to port 1 to disable all the LEDs on the NXI. When activity occurs on a port(s) or NXI, the LEDs will not light. Syntax: SEND_COMMAND ,'LED-DIS' Example: SEND_COMMAND System_1,'LED-DIS' Disables all the LEDs on the System_1 NXI. LED-EN Enable LEDs (default).
Programming RS-232/422/485 Send_Commands (Cont.) CHARDM Sets the delay time between transmitted characters in 1 millisecond increments. Syntax: SEND_COMMAND ,'CHARDM
Programming RS-232/422/485 Send_Commands (Cont.) HSON Enables RTS (ready-to-send) and CTS (clear-to-send) hardware handshaking. Syntax: SEND_COMMAND ,'HSON' Example: SEND_COMMAND RS232_1,'HSON' Enables hardware handshaking on the RS232_1 device. RXCLR Clears all characters in the receive buffer waiting to be sent to the Master Card.
Programming RS-232/422/485 Send_String Escape Sequences RS-232/422/485 Send_String Escape Sequences 27,17, Sends device-specific break characters for a specified duration. Syntax: SEND_STRING ,"27,17,
Programming IR / Serial Ports (8 - 15) Channels IR / Serial Ports Channels 00001 - 00229 IR commands. 00229 - 00253 May be used for system call feedback. 00254 Power Fail. (Used with the 'PON' and 'POF' commands). 00255 Power status. (Shadows I/O Link channel status). 00256 - 65000 IR commands. IR/Serial Send_Commands The following IR and IR/Serial Send_Commands generate control signals for external equipment.
Programming IR/Serial Send_Commands (Cont.) CTOF Sets the duration of off time (no signal) between IR pulses for channel and IR function transmissions. Off time settings are stored in non-volatile memory. The factory default for channel off time is 5 (.5 second). This command is associated with the SP (single pulse) and CP (clear pulse) commands.
Programming IR/Serial Send_Commands (Cont.) POF Turns off a device, based on input Link. • If at any time the IR sensor reads that the device is on (such as if one turned it on manually at the front panel), the card automatically attempts to turn the device back off. • If three attempts fail, the card will continue executing commands in the buffer. • If there are no commands in the buffer, the card will continue to try until a 'PON' or 'POD' command is received.
Programming IR/Serial Send_Commands (Cont.) SET IO LINK Links an IR or Serial port to an I/O channel for use with DE, POD, PON and POF commands. The I/O status is automatically reported on channel 255 on the IR port. Syntax: SEND_COMMAND ,"'SET IO LINK ' Variable: Number = 1-8; set the I/O channel to 0 to disable I/O link settings. Example: SEND_COMMAND IR_1," 'SET IO LINK 1'" Sets the IR_1 port link to I/O channel 1.
Programming IR/Serial Send_Commands (Cont.) XCHM Changes the IR output pattern for the XCH command. Syntax: SEND_COMMAND ,'XCH-' Variable: Mode = 0-4 Example: SEND_COMMAND IR_1,'XCH 3' Sets the IR_1 device's extended channel command to mode 3. Mode 0 Example (default): [x] [x] SEND_COMMAND IR_1, 'XCH 3' Transmits the IR code as 3-enter. SEND_COMMAND IR_1, 'XCH 34' Transmits the IR code as 3-4-enter. SEND_COMMAND IR_1, 'XCH 343' Transmits the IR code as 3-4-3-enter.
Programming IR/Serial Send_Commands (Cont.) ZAP LOW Deletes all IR data stored in the NXI ports 8-11. Syntax: SEND_COMMAND , 'ZAP LOW' Example: SEND_COMMAND IR_1, 'ZAP LOW' Deletes IR commands in ports 8-11 of the IR_1 device. Input/Output Send_Commands The following Send_Commands program the I/O ports on the NXI. I/O SEND_COMMANDS GET INPUT Gets the input channels active state. • An active state can be high (logic high) or low (logic low or contact closure).
