NL100/105 Network Link Interface

with the device connected to the RS-232 port. This is a fixed rate (i.e., it is not
a maximum baud rate or an autobaud rate). The default is 115k bps.
Disabled - The TLink communications port is disabled.
2.3.3.2 RS485 Config
Currently there are no dataloggers with RS485 ports, or RS485 to RS-232
interfaces for a datalogger's CS I/O port. The RS485 communication option
will be implemented in the future.
2.3.3.3 CS I/O Config
This option is used to configure the NL100/105's CS I/O port. The port can be
configured for PakBus communication, as a TcpSer serial server, or as a
PakSer serial server.
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 CS I/O 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
CS I/O port has the following settings:
CS I/O SdcAddr/bps - This option is used to set up the CS I/O port to
communicate with the datalogger as an addressable SDC device or a
modem enabled device. If SDC7 or SDC8 is chosen, the NL100/105 will
use that address to communicate with the datalogger in a synchronous
communication mode. If one of the baud rates is chosen, the NL100/105
will communicate with the datalogger as a modem enabled device using
the selected baud rate. If another SDC device is connected to the
NL100/105, the two devices must use different SDC addresses.
CS I/O 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.
