Connections and Wiring

FIG. 2 shows the layout of the connectors and components located on the rear of the

NI-700 NetLinx Integrated Controller.

Wiring a Power Connection

Use a 12 VDC-compliant power supply to provide power to the NI-700 through the

rear 2-pin 3.5 mm mini-Phoenix connector (FIG. 2). Use the previous power

requirements information to determine the power draw.

The incoming PWR and GND cable from the power supply must be connected to

their corresponding locations within the PWR connector. Refer to the NetLinx

Integrated Controllers Instruction Manual for more detailed wiring connection

information.

RS-232/422/485 Wiring Connector Information

FIG. 3 shows the pinout and wiring specification information for the rear

RS-232/RS-422/RS-485 (DB9) Device Ports. These ports support most standard

RS-232 communication protocols for data transmission (NI-700 uses Ports 1 & 2).

WARNING: When wiring the 422/485 connections, do NOT use pre-made 9-wire

cable or connect the wire in the cable to any connection that will not be used by the

DB9 serial port. Only use wiring that connects the needed pins.

Ethernet 10/100 Base-T Connector

A standard CAT5 Ethernet cable provides 10/100 network connectivity between the

Integrated Controller and the network (FIG. 4).

Note: On NetLinx Masters (such as those aboard the NI-700), from within the Telnet

or Terminal applications; you can send the SET ETHERNET MODE command to

assign the speed of your Ethernet connection.

Sample NI-700 command:

SET ETHERNET MODE AUTO

The NI-700 only allows you to set the Ethernet mode to AUTO negotiate the

Ethernet connection speed. Using any of the other connection modes (10 Half/

Full or 100 Half/Full) results in an error message.

Program Port Baud Rate Settings

The Configuration DIP switch is located on the front panel. 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).

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.

Preparing the NI-700 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 entry in the Online Tree tab 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.

Configuring the NI-700 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 pro-

cess 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 Informa-

tion 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.
