NXU-2A Troubleshooting
The following table may be used to troubleshoot any problems you may encounter during
installation or operation of the NXU-2A.
Table 5-1
Troubleshooting
Symptom:
Possible Causes:
Main Power LED is not illuminated
Check that AC adapter is operational and
firmly plugged in.
Cannot place the unit into Command Mode as
outlined in Section 3.3
Check RS-232 connections
Verify terminal settings: 115200 baud, 8 data
bits, 1 stop bit, no parity
(
Note: if you have previously used Command
Mode to set the serial port baud rate to a
value different than 115200 then you must use
the new baud rate to enter Command Mode
.)
Verify that no flow control, either hardware or
software, is being used in your terminal
program.
Make sure you wait at least 5 seconds, and
then type +++ (three plus signs) within 1
second.
Settings made in Command Mode do not
appear to take effect.
You must issue a SAVE command after
making changes in order to save the new
settings and restart the NXU-2A.
Client and Server units are properly
configured and online but LINK ACTIVE is
not on.
Verify that both the Client and Server NXU-
2A units are “visible” on the network by
“pinging” their IP addresses from a network-
connected computer.
Verify that the Server’s IP address has been
programmed into the Client using the SRVRIP
command per Section 0 The port used by the
NXU-2A for receiving audio from the
network which defaults to 1221. Under
normal circumstances, this should not be
changed. The default value may be changed,
if necessary, by using the PORT command.
Type PORT <port number> and press ENTER
to select a new VoIP port. The port number
must range from 1 to 65535 and be different
from the command port.
