No Response to
Commands in ML Net
1. Verify that the master device and the Nº532 are properly
connected together with a router.
2. Verify that the Nº532 network setup is correct. Access to the
internal Web page via a computer is required to verify the
network settings of the Nº532.
3. If status information is received on the master device, but
commands cannot be sent to the amplifier, then verify that a
Link2 connection does not also exist to the amplifier. If both
Link2 and ML Net are connected to the amplifier, the Nº532
ignores ML Net commands but status information is still sent.
Link2 Not Working
1. Verify that the master device and the amplifiers are properly
daisy-chained.
2. Refer to the product documentation of each device to verify
compatibility and the proper cabling.
3. Power down all of the devices, then power up the master device,
followed by each slave device. Allow each device to go through
its initialization process before powering up the next device.
Then cycle the master device through Standby mode. The
Standby LEDs should now be blinking in unison.
No Connectivity Via
Ethernet
• Verify that the network cables are properly connected between
the router, switch, or hub and the Nº532. If connecting to a
computer, verify that the computer network cable is in the
correct port.
• Verify the age of the router, switch, or hub. There may be a
communication issue with the Nº532 and older network
devices. Power cycle the Nº532 and use a newer router, switch,
or hub between the network and the Nº532.
• If connected directly to the computer, make sure a crossover
cable is used.
• Verify that the router and computer have valid IP addresses.
If All Else Fails...
1. Power-cycle the Nº532, waiting at least 10 seconds between
powering the Nº532 off and on.
2. Restore the default settings on the internal web page.
