Raven110 GPRS/EDGE AirLink Cellular Modem

Try adding a few seconds (no more than five seconds) of extra response time to
the datalogger or PakBus port.

For a PakBus datalogger, verify the PakBus address in the setup screen
matches that of the datalogger.

For networks with multiple PakBus ports, uncheck the ‘PakBus Port Always
Open’ options on all PakBus ports.

7.4 Using Wireless Ace 3G 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
Wireless Ace (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 7-1). Try connecting
with the datalogger using LoggerNet/PC400W. If a connection cannot be
established, close LoggerNet and reconnect with Wireless Ace 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 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
change takes affect. Click the Reset icon in Wireless Ace to the
reset the modem and implement the change.
