RavenXTG Sierra Wireless Cellular Modem

7.4 Using 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 7.4-1). 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 Raven GPRS/EDGE template file has been

loaded.

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.

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

NOTE

change takes affect. Click the Reset icon in AceManager to the

reset the modem and implement the change.
