NetLinx Integrated Controllers

Troubleshooting

This section describes the solutions to possible hardware/firmware issues that could arise during the

common operation of a Modero touch panel.

Troubleshooting Information

Symptom Solution

My NI Controller can’t obtain a

DHCP Address.

In requesting a DHCP Address, the DHCP Server can take up to a few

minutes to provide the address to the on-board Master.

• Verify there is an active Ethernet connection attached to the rear of

the NI-Series Controller before beginning these procedures.

•Select Diagnostics > Network Address, from the Main menu and

verify the System number.

• If the IP Address field is still empty, give the NI Controller a few

minutes to negotiate a DHCP Address and try again.

My NI Controller shows the same

IP Address after selecting DHCP

Server and clicking the GET IP

Information button.

In requesting a DHCP Address, the DHCP Server can take up to a few

minutes to provide the address to the on-board Master.

When using a controller that has previously been used; there may be

an instance where the IP Address was set as a fixed IP. In this case,

the address would need to be released so a new user could use a

DHCP server provided address.

• Access the HyperTerminal application and try to communicate to the

controller via the COM port.

• Type echo on and press ENTER to send the information to the unit.

• Type get ip to display the actual IP Address used by the unit.

• Release the static/fixed IP Addresses.

• Recycle power to the unit and retry obtaining a DHCP address

through NetLinx Studio 2.2.

My NI Controller still can’t obtain a

DHCP Address even after

completing the above

troubleshooting tip.

If the NI Controller is not connected directly to an open Ethernet wall

connector, but is rather connected to an Ethernet Hub

• Contact Technical Support for a resolution to issues with this type

of connection scenario.

I can’t detect the NI Controller and

my Status LED is blinking

irregularly.

The on-board Master is trying to establish communication.

• Give it a few moments and retry establishing communication using

NetLinx Studio 2.2.

• If the problem persists, cycle power to the unit and repeat the above

procedure. Another solution is to attempt communication via another

method (Program Port or IP).

• Refer to the Configuration and Firmware Update section on page 37

for more information.

NetLinx Studio only detects one of

my connected Masters.

Each Master is give a Device Address of 00000.

• Only one Master can be assigned to a particular System number. If

you want to work with multiple Masters, open different instances of

NetLinx Studio and assign each Master its own System value.

• Example: A site has an NXC-ME260/64 and an NI-4000. In order to

work with both units. The ME260/64 can be assigned System #1 and

the NI-4000 can then be assigned System #2 using two open

sessions of NetLinx Studio 2.2.
