Appendix C. NL200/201 Settings
C-9
Port Number
Specifies a numeric code for the port that the router will use. It will correspond
with one of the following:
0 CS I/O
1 RS-232
100 PakBus/TCP Connection — If the value of the port number is 100
or greater, the connection is made through PakBus/TCP.
Via Neighbour Address
Specifies the address of the neighbour/router that will be used to send messages
for this route. If the route is for a neighbour, this value will be the same as the
address.
PakBus Address
Specifies the address that the route will reach.
Response Time
Specifies the amount of time (in milliseconds) that will be allowed for the route.
Central Routers
This setting specifies a list of up to eight PakBus addresses for routers that are
able to work as Central Routers. By specifying a non-empty list for this setting,
the device will be configured as a Branch Router meaning that it will not be
required to keep track of neighbours of any routers except those in its own branch.
Configured in this fashion, the device will ignore any neighbour lists received
from addresses in the central routers setting and will forward any messages that it
receives to the nearest default router if it does not have the destination address for
those messages in its routing table.
C.5 TLS Proxy Server Tab
TLS Proxy Server
Enable/Disable the TLS Proxy Server. When doing TLS proxy communications,
the device’s TLS server maintains a secure TLS connection with a remote TLS
client and forwards information onto a datalogger using a standard TCP connection.
TCP ports and physical connections are configured below.
If the TLS Proxy Server is enabled and a datalogger is connected to
the CS I/O port, the datalogger will load its TCP stack in case it is
required to do TCP communications. Running the TCP stack
causes the datalogger to use more memory, leaving less for final
storage, etc. So if TCP/TLS server capability is not required, the
TLS Proxy Server should be left disabled.
TLS Proxy Server Port Number
When doing TLS Proxy communications, the NL200/201 TLS server maintains a
secure connection with a remote client. If the TLS Proxy Forward Physical Port is
specified to be the CS I/O port, the NL200/201 will then open a TCP connection
with the datalogger over the CS I/O port and do unencrypted data transfer with the
