Figure 4-1. NL201
Bridge Mode Enabled
The NL200/201 can be configured to bridge Ethernet and CS I/O communications
(Bridge Mode enabled). This mode is used for providing access to the internal IP
functionality of the CR800/850, CR1000, and CR3000 (e.g., web page access,
email, FTP, etc.). Bridge mode does not utilize PPP. Instead, raw IP packets are
transferred between the Ethernet and CS I/O connections.
Figure 4-2. Bridge Mode enabled
Bridge Mode Disabled
With Bridge Mode disabled, the NL200/201 can be configured to act as a serial
server and/or a PakBus router. The NL200/201 can act as a serial server and
PakBus router simultaneously. However, each physical port (RS-232 and CS I/O)
is only associated with one service (Pakbus router, serial server, Modbus/TCP
Gateway, etc.) at a time. Therefore, you can have an RS-232 serial server and a
CS I/O serial server, an RS-232 serial server and a CS I/O PakBus router, an RS-
232 PakBus router and a CS I/O serial server, or an RS-232 PakBus router and a
CS I/O PakBus router. In addition, the NL200/201 can act as TLS proxy server.
The TLS proxy server is independent of other modes.
