Using Multiple Netlinx Masters - AMX NetLinx Integrated Controller NI-4000 Instruction Manual

This tab represents the only way to change the System Number associated to the
active on-board NI Master. The Master must be rebooted to incorporate the new
System number.
2. Select the Change System selection box from the System to Change section.
3. Enter both the current and new system address values (this example uses 2).
4. Click the Change Device/System Number button. This configures the NI Master to accept the
new value and incorporate the information. The system information (in the OnLine Tree tab of
the Workspace window) refreshes and then displays the new information.
5. Click Done to close the Device Addressing dialog and return to the main program.
6. Click Reboot (from the Tools > Reboot the Master Controller dialog) and wait for the System
Master to reboot. The STATUS and OUTPUT LEDs should begin to alternately blink during
the incorporation. Wait until the STATUS LED is the only LED to blink.
7. Press Done once the Master Reboot Status field reads Reboot of System Complete.
8. Click the OnLine Tree tab in the Workspace window to view the devices on the System. The
default System value is one (1).
9. Right-click the associated System number and select Refresh System. This establishes a new
connection to the specified System and populates the list with devices on that system.
10. Use Ctrl+S to save your existing NetLinx Project with the new changes.
If the NetLinx device does not appear within the OnLine Tree tab of the Workspace
window of NetLinx Studio, make sure that the Integrated Controller's on-board Master
System Number (from within the Device Addressing tab) is correctly assigned.
If there is a problem, use a system value of zero (0) on the NetLinx device.
The Master by default is set to DEVICE 0. Connected NetLinx device addresses
can only be changed through the Protected Setup page. The new address is reflected
within the OnLine Tree tab of the Workspace window only after the devices are
rebooted and the system is refreshed.

Using multiple NetLinx Masters

When using more than one Master, each unit must be assigned to a separate System value.
A Master's System value can be changed but it's device Address must always be set to zero
(00000). The Device Addressing dialog will not allow you to alter the NetLinx Master address
value.
Example: Using NetLinx Studio 2.2 to work with an NXC-ME260/64 and NI-4000:
NetLinx Integrated Controllers
The NXC-ME260/64 could be assigned to System 1 (with a value of 00000).
The NI-4000 could be assigned to System 2 (with a value of 00000).
