3. Use AceManager to check modem communications with datalogger.
The modem’s “Host Serial Bytes Sent” and “Host Serial Bytes Received”
windows can indicate whether or not the modem is communicating with
the datalogger.
Establish a connection with the modem through the cellular network using
AceManager (click on the Modem menu item, Connect, UDP. Enter the
IP address, and click OK). Go to the Status group and note the “Host
Serial Bytes Sent” and “Host Serial Bytes Received” values (FIGURE
7-2). Try connecting with the datalogger using LoggerNet/PC400. If a
connection cannot be established, close LoggerNet and reconnect with
AceManager and compare the current values with the previous values.
If the values are the same, the modem is not attempting to make a
connection with the datalogger. Check that the GPRS/EDGE_XXX.xml
template file has been loaded (Section 5, Using AceManager to Program
the Modem).
If the “Host Serial Bytes Sent” increased, the modem attempted to connect
to the datalogger, but the response from the datalogger did not make it
back to the modem. Check the interface between the modem and the
datalogger (Section 4.2, Datalogger Site Equipment).
If both values incremented, the modem and the datalogger are
communicating. Try adding some extra response time in LoggerNet.
Baud rate changes require the modem to be reset before the
change takes affect. Click the Reset icon in AceManager to the
reset the modem and implement the change. NOTE
