A.4.4 Example Programs for Data Callbacks via a CR1000
Datalogger Router
To do data callbacks via a datalogger router with COM220 and RF401s or
MD485s, they must all be configured to communicate with one another. In
addition, two programs are necessary: one for the datalogger router and one for
the remote datalogger. Below are example programs for a datalogger router
and a remote datalogger. For these examples, the COM220 is configured for
SDC7 and the router datalogger has the following settings (you can enter these
settings via the datalogger keypad or from the LoggerNet status table):
PakBusAddress = 2, IsRouter = 1 or True, and BeaconSDC8 = 30, enabling the
router to discover the remote. The remote datalogger’s PakBusAddress = 1. In
addition, the RF401s or MD485s are set for CSDC8 (see the RF401 or MD485
manual for directions on configuring these devices).
Program for CR1000 Router:
'Router program for data callback via router w/ phone link to LoggerNet
'Phone to MD485 or RF401 w/ DL at Base
'Router PakBus Address = 2, IsRouter = 1, BeaconSDC8 = 30 to discover Remote DL
which has PBA = 1
'Router COM220 = SDC7; Base RF401 CSDC8; Remote RF401 CSDC8.
'LoggerNet PakBusPort has PBA = 4094
