Appendix C. NL200/201 Settings
All of the NL200/201 settings available from the Settings Editor in DevConfig
are described below.
C.1 Main Tab
Model (read only)
Model name.
Serial Number (read only)
Specifies the NL200/201 serial number assigned by the factory.
OS Version (read only)
Operating system version currently in the NL200/201.
Compile Date (read only)
Operating system compile date.
Bridge Mode
This setting is used to configure the device’s mode of operation.
Bridge Mode Disabled
With Bridge Mode disabled, the serial server (RS-232 or CS I/O),
PakBus®, and secure proxy server functionalities are available. Refer to
the respective device settings for the configuration of these functionalities.
Bridge Mode Enabled
With Bridge Mode enabled, the device will act as a bridge from Ethernet
to CS I/O. All IP packets that come in to the device via Ethernet will be
communicated to a datalogger over the CS I/O port. Some filtering is
done in order to minimize the amount of traffic on the CS I/O port but
every packet that is transmitted to the datalogger is sent intact as a
complete Ethernet/TCP packet. This enables the datalogger to use its
TCP/IP stack to interpret the packet, and therefore, all of the datalogger’s
TCP services are available. In bridge mode, none of the other device
settings are valid and all other functionality is disabled. All settings (i.e.,
IP, netmask, gateway) are configured in the datalogger. However, in
bridge mode, the device will intercept any TCP traffic on the “TCP
Configuration Port Number.” This allows the device to still be configured
remotely by IP connection using DevConfig. The “TCP Configuration
Port Number” is a user setting with a default value of 6786.
