PakBus Networking Guide

4.2 LoggerNet PakBus Setup

4.2.1 PakBusPort

A PakBus port must be set up in the device map prior to adding a PakBus

datalogger. In order to communicate to a datalogger via another datalogger

from LoggerNet's Connect window (i.e., communicating with a CR205 via a

CR10XPB) the datalogger through which you will be communicating must be

set up as a router. This is done by entering the number of remote dataloggers to

which the router will be connecting in *D15, parameter 2.

4.2.2 PakBus Port is Dialed

Typically, a PakBus port is always active (open) so that any incoming packets

that are transmitted can be received. When this check box is enabled, the

PakBus port is only active when communication is taking place with the device.

If a phone modem or RF400 Series radio is represented in the Setup map, the

port is ‘dialed’ regardless of this setting. Otherwise, other devices or software

would not be able to use the PC’s phone modem, and charges might be incurred

for keeping the phone link active.

You will want to enable this option if there is any reason that you will need to

use the root communications port for other devices or software, regardless of

whether a phone modem is being used (e.g., if the COM port is also being used

to communicate with a Storage Module using SMS).

5. Communication Device Setups

5.1 RF400 Series

Most PakBus networks involve RF400s even though they are often not

represented in the LoggerNet device map. The rule-of-thumb for using RF400s

in a PakBus network is that all RF400s in the network be configured exactly the

same, with one exception. The RF400’s Active Interface should be suited to the

device’s capability and according to any other devices connected to the PakBus

device.

RF400 Series can be configured using the PakCom software that ships with

them or LoggerNet’s Terminal Emulator.

5.1.1 Active Interface

The preferred port type for PakBus communications is CSDC because it uses

less datalogger CPU resources than M.E. If the datalogger has a modem

enabled device attached, the RF400 must be configured for CSDC. If there is

already a CSDC 7 device connected, change the CSDC setting to 8 in

PakCom’s Radio Settings \ OS Download, I/O Terminal. This is done in the

RF400’s Advanced Setup, Interface Parameters.
