Configuration
3.1
General
This section explains all settings and level adjustments that configure the NXU-2A. It is not
necessary to remove the NXU-2A cover to configure the unit.
3.2
Configuration Details
Configuring an NXU-2A or pair of NXU-2As requires that you allocate an IP address for each
unit, and that you designate one unit as a Client and one unit as a Server (explained in
subsequent paragraphs). Initial configuration is accomplished by attaching a serial RS-232
terminal to J4. If the unit already has an IP address and is on a network, configuration may be
done by connecting to the unit’s IP address via telnet or with a web browser. Each method of
configuration is discussed below.
NOTE:
The NXU-2A comes from the factory configured as a Server with the
following default settings:
IP Address:
192.168.1.200
Subnet Mask 255.255.255.0
Gateway IP
0.0.0.0
If the above network parameters are compatible with your network then you may attach the
NXU-2A to your network and use your web browser or telnet client to configure the NXU-2A as
outlined in Section 3.6 Network Configuration.
NOTE:
To restore the factory default conditions, remove and reapply power
to the unit
while rear panel switch “SW1” (
DEFAULTS
) is depressed. When the
front pan
el LED’s have blinked, release the switch, and the unit will be
operational using the JPS factory default parameters.
Any previously
assigned user parameters will be lost during this process.
3.3
Serial Port Configuration
To configure the NXU-2A using the serial port, connect a standard serial cable from a suitable
COM port on your PC to J4 on the NXU-2A rear panel. A standard DB-9 straight-through
cable (which should work on most PCs) is included with the NXU-2A. The NXU-2A comes
pre-configured with the serial port set at 115200-baud, 8 data bits, no parity, and 1 stop bit. No
hardware flow control is used or needed. In order to configure the NXU-2A you will need to
know which COM port you are connected to on your PC.
