3.2.3 Automatic Node Assignment - Subnet16™ Gateway

(-485 Only)

Through the use of the Configuration Tag, a Subnet16 Gateway can automatically

assign the Node ID number to a controller connected via Subnet16 network. Follow the

steps below to allow a Subnet16 Gateway to automatically assign the Node ID number to

a Cobalt HF-CNTL-485-01.

With the HF-CNTL-485-01 disconnected from the Subnet16 network, place the

Configuration Tag in the antenna’s RF field and cycle power to the HF-CNTL-

485-01controller.

After power returns to the unit remove the Configuration Tag from RF range.

Verify that all Node ID LEDs are off - indicating that the controller’s Node ID

number has been reset to

00.

Connect the controller to the Subnet16 network and cycle power to the Gateway

and Subnet16 network bus.

While the Gateway is restarting, place the Configuration Tag in the antenna’s RF

field. Allow several seconds for the Gateway to recognize the controller and

assign it an available Node ID number. Remove the Configuration Tag from RF

range.

3.2.4 Automatic Node Assignment - Subnet16™ Hub

(-485 Only)

Subnet16 Hubs, which have four independent controller ports, automatically assign each

attached RFID controller the corresponding Node ID number of the port to which it is

connected. For example, if a controller is attached to port 1 on the Hub, it will be

assigned Node ID 01. If a controller with a previously configured Node ID number of 03 is

connected to port 2, the Hub will override the controller’s current Node ID number and will

automatically change it from 03 to 02.

To have the Hub automatically assign the Node ID number to the RFID controller, follow

the steps below:

Connect the HF-CNTL-485-01 to the Subnet16 Hub

Place the Configuration Tag in the antenna’s RF field and cycle power to the HF-

CNTL-485-01controller.

After power returns to the unit, remove the Configuration Tag from RF range.

Verify that all Node ID LEDs are off - indicating that the controller’s Node ID

number has been reset to

00.

Cycle power to the Hub and Subnet16 network bus.

While the Hub is restarting, place the Configuration Tag in the antenna’s RF field.

Allow several seconds for the Hub to recognize the controller and assign it the

corresponding Node ID number of the controller port for which it is attached.

Remove the Configuration Tag from RF range.
