AMX NXC-ME260-64 Program Port Connections/Wiring, Preparing the ME260-64 for Serial Communication

Program Port Connections/Wiring

The NXC-ME260/64 is equipped with two Program ports. One is located on the front panel and the other is on the rear for easy access. The port on the front panel is an RS232 (male) connector and the rear port is a grey 5-pin (male) connector. Use a Programming cable to connect the Program port to your PC's COM port to communicate with the Master card. Then, you can download NetLinx programs to the Master card using the NetLinx Studio 2 software program.

Wiring a power connection

Use a 12 VDC-compliant power supply to provide power to the Master through the rear 2-pin 3.5 mm mini-Phoenix. Use the power requirements information listed in the Specifications table to determine the power draw. The incoming PWR and GND cable from the PSN power supply must be connected to their corresponding locations within the PWR connector. Refer to the unit’s instruction manual for more detailed wiring connection information.

RS-232/422/485 wiring connector information

The following table shows the pinout and wiring specification information for the front panel RS-232 (DB9) Program Port.

Program Port Connector Pinouts (RS232)

Pin	Signal	Function
1	N/A	Not used
2	RXD	Receive data	1 2 3 4 5
3	TXD	Transmit data
4	DTR	Not used
5	GND	Signal ground
6	DSR	Not used	6 7 8 9
7	RTS	Request to send
8	CTS	Clear to send
9	N/A	Not used

RJ-45 Connections

Use a standard CAT5 Ethernet cable to provide communication between the Master and external NetLinx devices.

Ethernet 10/100 Base-T Connector

The Ethernet cable provides 10/100 network connectivity between the panel and the NetLinx Master (FIG. 2).

Note: DIP switch 1 activates/deactivates the Program Run Disable Mode. DIP Switches 2,3, and 4 must remain OFF at all times.

Setting the Configuration (Program Port) DIP Switch

1.Disconnect the power supply from the rear 2-pin PWR (green) connector.

2.Set DIP switch positions according to the information listed in the previous Baud Rate Settings table.

3.Reapply power to the unit.

SPE Port Connection/Wiring

Use an RJ-11 cable to connect the NXC-ME260/64 to an AXB-SPE (FG714) Slave Port Expander. The EXPANSION OUT port on the rear panel of the NXC-ME260/64 connects to the EXPANSION IN port on the rear panel of the AXB-SPE. You can daisy chain multiple AXB-SPE's by connecting the EXPANSION OUT on the primary AXB-SPE to the EXPANSION IN port on the secondary. The connecting RJ-11 cable should not exceed 6" in length. Repeat this process to connect up to nine AXB-SPE's.

Preparing the ME260-64 for Serial Communication

1.Launch NetLinx Studio 2.x (default location is Start > Programs > AMX Control Disc > NetLinx Studio 2 > NetLinx Studio 2).

2.Select Settings > Master Communication Settings, from the Main menu, to open the Master Communication Settings dialog box.

3.Click the Communications Settings button to open the Communications Settings dialog.

4.Click the NetLinx Master radio button (from the Platform Selection section) to indicate you are working with a NetLinx Master.

5.Click the Serial radio button (from the Transport Connection Option section) to indicate you are connecting to the Master via a COM port.

6.Click the Edit Settings button (on the Communications Settings dialog) to open the Serial Settings dialog and set the COM port parameters (used to communicate to the NetLinx Master).

7.Click the OK button three times to return to the main application.

8.Right-click the Online Tree tab entry and select Refresh System.

9.Assign a System Value by using Diagnostics > Device Addressing from the Main menu.

10.Enable the Change System selection by clicking on it and then enter the current and new System values.

11.Click the Change Device/System Number button and when finished click Done.

12.Select Tools > Reboot the Master Controller to access the Reboot the Master dialog, then click Reboot to restart the Master and incorporate any changes.

13.Once the dialog replies with "Reboot of system complete", click Done and then click the OnLine Tree tab in the Workspace window to view the devices on the System.The default System value is one.

14.Right-click on the Empty Device Tree/System entry and select Refresh System to re-populate the list.

Baud Rate Settings

The Program Port DIP switch is located on the card’s internal circuit board. For cards installed in modules, you must remove the front panel to access the DIP switch. Use this internal DIP switch to set the baud rate used by the Program port for communication. Use this DIP switch to set the baud rate for the Program Port, according to the settings shown in the following table. Make sure the baud rate you set matches the baud rate on your PC's NetLinx COM Settings before programming the unit.

By default, the baud rate is set to 38,400 (bps).

Baud Rate Settings

Baud Rate	Position 5	Position 6	Position 7	Position 8
9600 bps	OFF	ON	OFF	ON
38,400 bps	OFF	ON	ON	ON
(default)
57,600 bps	ON	OFF	OFF	OFF
115,200 bps	ON	ON	ON	ON

Note: The Program Port DIP Switch is also used to set Program Run Disable (PRD) mode. The PRD mode prevents the NetLinx program stored in the Master from running when you power up the NXC-ME260/64.

Configuring the ME260-64 for Ethernet Communication

Before continuing, complete the COM port steps above.

1.Connect an Ethernet cable to the unit’s rear Ethernet connector.

2.Select Diagnostics > Network Address from the Main menu and enter the System, Device (0 for a Master), and Host Name information.

3.To configure the Address:

•Use a DHCP Address by selecting the Use DHCP radio button, then click the GET IP button (to obtain a DHCP Address from the DHCP Server), click the SET IP Information button (to retain the new address), and then finish the process by clicking the Reboot Master > OK buttons.

•Use a Static IP Address by selecting the Specify IP Address radio button, enter the IP parameters into the available fields, then click the SET IP Information button (to retain the pre-reserved IP Address to the Master), and then click the Reboot Master > OK buttons to finish the process.

4.Repeat steps 1 - 5 from the previous section but rather than selecting the Serial option, choose TCP/IP and edit the settings to match the IP Address you are using (whether Static or IP).

5.Click on the Authentication Required radio box (if the Master is secured) and press the User Name and Password button to enter a valid username and password being used by the secured Master.

6.Click the OK button three times to return to the main application.
