Programming the Hub System

NOTE: The nodes will synchronize 3 to 5 minutes after you disconnect VMMI from the hub system.

1. Make the necessary programming changes that only affect local operation.

2. Program the board configuration to match DXNET or FXNET boards to their assigned slots, and inspect

the installation.

a. Verify that the system recognizes these boards as DXNET or FXNET boards, that the boards are

operational, and that there are no alarms present on the installed boards. Resolve any alarm problems

before proceeding.

b. Using the board programming menu, set the operating protocol for DXNET or FXNET boards to

4ESS, and leave all other program settings to their default values.

3. Assign the hub’s extension numbers that are to be associated with network operation. Remember, use a

different block of intercom numbers than those used at each node.

4. If you plan for voice announce intercom calls, enable call announce on a per channel basis.

At the hub, use network programming to set the networking parameters. This programming subsection is available

as a selection item under System Programming.

Network Properties

Use this option to enable or disable the hub operation. Since the hub controls the system-to-system of the nodes,

the system grants each node access to a particular block of intercom numbers (also called extension numbers)

through the hub database.

Network Disable Status

Enable or disable the network database status as a hub.

Network Extension Length

Set the extension length for the hub and each node’s stations to be either three or four digits.
