NL100/105 Network Link Interface
9
CR10X, CR510, CR23X, 21X, and CR7 dataloggers ship with an
array-based operating system. Array-based dataloggers do not
support the PakBus communications protocol. Therefore, you
cannot communicate with them over a port configured for
PakBus. However, the CR10X, CR510, and CR23X dataloggers
can be special-ordered with a PakBus operating system. Check
with your technical support representative for details.
PakBus - This option is only used when setting up the NL100/105 to
communicate with other PakBus devices in the network. Packets transferred
over the RS-232 port in this mode are framed as PakBus packets; therefore, any
device attached to the port must be capable of PakBus communication. PakBus
is a packet based communications protocol developed by CSI. One of the
advantages of PakBus is that other communications protocol packets, such as
TCP/IP or MODBUS, can be "wrapped" in a PakBus packet and transferred
among PakBus devices in the network, thus allowing various communication
protocols within one network. When configured for PakBus, the NL100/105's
RS-232 port has the following settings:
RS-232 bps - This is the bits per second (bps) at which the NL100/105
will communicate using the RS-232 port. This is a fixed rate (i.e., it is not
a maximum baud rate or an autobaud rate). Note that the CR10XTD-PB
and the CR510TD-PB can communicate at a maximum baud rate of 9600
bps, so to communicate with one of those dataloggers, this setting must be
9600 bps or less. The default rate is 115K bps.
PakBus Beacon Interval - The NL100/105 can be set to transmit a beacon
to a PakBus network via the selected port. The beacon allows the
NL100/105 to determine which devices in the PakBus network it can
communicate with. Note that because a beacon is broadcast to all devices,
it can interfere with other communication in the network (such as RF), so a
frequent beacon may not be desirable. If 0 is entered, no beacon will be
sent; the default beacon is 60 seconds.
TcpSer - This option configures the NL100 to act as a TCP/IP based serial
server when communicating with a datalogger over its RS-232 port.
RS-232 bps - This is the bits per second (bps) at which the NL100/105
will communicate using the RS-232 port. This is a fixed rate (i.e., it is not
a maximum baud rate or an autobaud rate). Note that the CR10(X) and the
CR510 can communicate at a maximum baud rate of 9600 bps, so to
communicate with one of those dataloggers, this setting must be 9600 bps
or less. The default setting is 115K bps.
RS-232 serial server port number - Enter the port number, in the range of
1 to 65000, that will be used for communication. The default port number
is 6784.
PakSer - The RS-232 port of the NL100/105 can be configured as a PakBus
serial server. This sets up the device as a serial server. In this mode, PakBus
framing is removed from the packet and routed via the RS-232 port. Typically,
the attached device would be one that does not support PakBus communication
(such as an array-based CR10X).
