NL100/105 Network Link Interface

Version information may be requested by a Campbell Scientific Applications
Engineer when troubleshooting a communication problem.
The Ethernet physical address that is displayed is a hexadecimal
representation of the address assigned to this device. An Ethernet
address is unique to the specific device to which it is assigned.
This assignment is made at the factory and cannot be changed by
the user. The Ethernet physical address is not the same as the
TCP/IP address.
2.3.2 Show
The Show command displays the current settings for the NL100/105 ports, the
user password, and watchdog time-out.
2.3.3 Edit
The Edit menu option is used to set up the communications link for the
NL100/105. You should work closely with your network administrator to
determine the correct settings for your specific network.
You can progress through the menu options by pressing <Enter>. If you make a
mistake after entering a setting, press the up cursor arrow on your keyboard to
return to the previous setting. All available selections will be listed on the
prompt line enclosed in parenthesis, with the current setting displayed in
brackets at the end of the selections (e.g., [disabled]). Help for a setting can be
displayed by pressing F1 or the ? key.
Once changes have been made and you have come to the end of the prompts for
the communication options, you can choose "save" to put the new settings into
effect or "cancel" to disregard the changes and keep the current settings.
2.3.3.1 TLink Config
This setting is applicable to the NL105 only, and is used when communicating
with a CR9000 datalogger. TLink is an interface used to communicate with a
CR9000 datalogger over an Ethernet connection. A physical connection is
made between the TLink port on the CR9000's 9031 CPU module and the port
marked TLink on the NL105. TLink Config is used to set the TLink
communications port to one of three options:
TcpSer - The NL105 acts as a serial server for the TLink port. A serial server is
a device that allows serial communication over a TCP/IP communications link.
When configured as a serial server, there is one parameter to set:
TLink Serial Server Port Number - Enter the port number, in the range of
3000 to 65000, that will be used for TLink communication. The default
port number is 6781.
232-Bridge - The NL105 transparently passes data between the TLink port and
its RS-232 ports. The 232-Bridge configuration has only one setting, RS-232
bps. This is the bits per second (bps) at which the NL105 will communicate
