Installing Into an Equipment Rack
Use the optional AC-RK Accessory Rack Kit (
FG515
) to mount the Controller into a standard 19"
equipment rack.
1.
Discharge the static electricity from your body by touching a grounded object.
2.
Align the front of the NI-900 through any of the three rectangular openings on the AC-RK.
3.
Use the included mounting screws to secure the unit’s faceplate to the AC-RK.
4.
Thread the cables through the opening in the equipment rack. Allow for enough slack in the
cables to accommodate for movement during the installation process.
5.
Reconnect all cables to their appropriate source/terminal locations. Verify that the terminal
end of the power cable is not connected to the a power supply before plugging in the 2-pin
power connector.
6.
Align the ends of the AC-RK with the screw openings along the sides of the equipment rack.
7.
Secure the AC-RK to the rack by using the four #10-32 screws (80-0186) and four #10
washers (80-0342) supplied in the kit.
8.
Apply power to the unit to complete the installation process.
Connections and Wiring
Preparing Captive Wires
You will need a wire stripper and flat-blade screwdriver to prepare and connect the captive wires.
Note
: Never pre-tin wires for compression-type connections.
1.
Strip 0.25 inch (6.35 mm) of insulation off all wires.
2.
Insert each wire into the appropriate opening on the connector (according to the wiring dia-
grams and connector types described in this section).
3.
Tighten the screws to secure the wire in the connector. Do not tighten the screws excessively
doing so may strip the threads and damage the connector.
Wiring a Power Connection
To use the 2-pin 3.5 mm mini-Phoenix connector with a 12 VDC-compliant power supply, the
incoming PWR and GND cables from the external source must be connected to their corresponding
locations on connector (FIG. 2).
1.
Insert the PWR and GND wires on the terminal end of the 2-pin 3.5 mm mini-Phoenix cable.
Match the wiring locations of the +/- on both the power supply and the terminal
connector.
2.
Tighten the clamp to secure the two wires.
3.
Verify the connection of the 2-pin 3.5 mm mini-Phoenix to the external 12 VDC-compliant
power supply.
RS-232/422/485 Connector Information
FIG. 3 shows the pinout and wiring specification information for the rear RS-232/RS-422/RS-485
(DB9) Device Port. This port support most standard RS-232 communication protocols for data
transmission (the NI-900 uses only Port 1).
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-900), 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-900 command:
SET ETHERNET MODE AUTO
The NI-900 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.
