Section 6: Viewing/setting Ethernet address

The Series NRX trip unit is used as the means to display and modify
the programmed Ethernet settings of the ECAM Module. All modules
are shipped with the following factory default settings:
DHCP Enabled False
IP Address 10.0.0.2
Subnet Mask /26
Default Gateway 10.0.0.1 (the first two bytes are the same as the IP
Address)
For the Series NRX Ethernet Communications Adapter Module, nine
communication settings are available and can be viewed as shown in
Table 3. A block diagram of the setting sequence and programming
options is shown in Figure 12.

NRX 520M
Setting
Setpoint Number Name
DHCP Enabled SP00
IP Address MSB SP01
IP Address SP02
IP Address SP03
IP Address LSB SP04
Subnet Mask (CIDR Notation) SP05
Default Gateway SP06
Default Gateway SP07
Reset Pin
SP08
The Subnet Mask uses Classless Inter-Domain Routing (CIDR)
notation to minimize the number of setpoints required. In CIDR
notation, a prefix is shown as a 4-octet quantity, followed by the
"/" (slash) character, followed by a decimal value between 0 and 32
that describes the number of significant bits. For example, network
192.168.0.0 with a network mask of 255.255.0.0 is represented as
192.168.0.0/16, with the "/16" indicating the most significant 16
bits are ones and the least significant 16 bits are zeros. Similarly,
192.168.99.0/26 indicates the most significant 26 bits are ones
and the least significant 6 bits are zero. This represents a mask of
255.255.255.192, resulting in 64 available addresses from 192.168.99.0
to 192.168.99.63 for devices on this subnet.
The first 2 bytes of the default Gateway are the same as the first 2
bytes of the IP Address. The last 2 bytes (octets) are set as SP06 and
SP07 .
The Reset PIN setpoint (SP08) is provided to clear passwords and
ECAM configuration information. Three special numeric values may be
entered to clear the Control Password, reset the admin password, or
reset the ECAM configuration information:
• 9 Reset control password
• 15 Reset admin password
• 31 Reset ECAM configuration information

NRX 520M Trip Unit Communication Settings
To set or view the settings using the Series NRX 520M Trip Unit,
depress and hold the Reset/Battery Test Button located on the front
of the trip unit for approximately five seconds until the address
information is displayed. This button must be held in continuously
during the process. The Series NRX trip unit display will then alternate
between 'SP00' and the programmed DHCP setting.
To change the DHCP selection, depress the trip unit SCROLL Display
Button to increment the value shown. Users may simultaneously
depress and hold in the SCROLL and Reset/Battery Test Buttons for
fast advance. The next setting will be displayed when the Reset/Battery
Test Button is released and then once again depressed.
Once the last setting (SP08) has been viewed and the Reset/Battery
Test Button has been released, the new network setttings will be
saved to the Series NRX 520M Trip Unit.
NRX 1150 Trip Unit Communication Settings
Programming the communication settings using the NRX 1150
graphical user interface follows a similar procedure.
Press the <ESC> button to navigate to the top level display.
Use the right and left arrow buttons to navigate to the PGM Set icon.
Press the <SEL> button to select the PGM Set menu.
Scroll down to "Comm Settings" and press the <SEL> button.
Scroll through the Comm Settings (SP00 to SP08) using the right and
left arrow buttons. Change the values using the up and down arrow
buttons. Press the <SAVE> button to save the communication settings.
