Section 4. Setting up Datalogger Networks
Advanced
Call-back Enabled – Enabling call-back tells LoggerNet to watch for a call-
back from the datalogger on this port.
Dataloggers depicted in the Setup Screen must be configured for call-back as
well. For mixed array dataloggers, set the Call-Back ID to some value other
than 0 to accomplish this. For CRBasic dataloggers, enable the Call-Back
Enabled check box for those dataloggers which should be enabled for call-
back.
TCP Listen Only – When selected, LoggerNet will never attempt to make an
outgoing TCP Link on this IPPort. It will only listen for an incoming TCP call-
back. This option is useful for a datalogger doing TCP call-back from behind a
firewall. In this case, it is not possible to create a TCP connection from
LoggerNet to the datalogger and any time spent attempting to do so will be
wasted and may result in missing incoming connection attempts.
Extra Response Time – In this field, specify the additional time that
LoggerNet should delay before terminating the communications link if there is
no response from the IPPort. Additional time may be needed in instances
where the communications link is noisy or network traffic is heavy.
Delay Hangup – The amount of time, in seconds and milliseconds, that
LoggerNet should delay before hanging up the link to the device. If a new
command to the device is issued before the delay has expired, communication
will not be terminated.
IP Port Used for Call-back – If call-back is enabled for the IP port, enter the
port number that LoggerNet should open and monitor for incoming call-back
messages.
AirLink Modem Name – If an AirLink modem is being used, enter the Device
ID set in it. By default, this is the 11-digit Electronic Serial Number of the
device.
When entering the IP address, do not use leading zeros for the
address numbers. For example use 123.123.2.34 instead of
123.123.002.034.
NOTES
LoggerNet waits a certain amount of time for a response from
each device in a communications path. The extra response times
defined for the communications link are cumulative. Therefore,
the amount of time spent waiting for a device to respond is the
sum of all Extra Response Times defined, plus the default
response time for each device in the link. Add the minimum
time necessary since very long response times can delay other
scheduled events while waiting for a device that is not
responding.
4.2.4.3 TAPIPort (Telephony API)
The TAPI port uses the phone modems that have been installed and configured
in Windows. This eliminates the need for LoggerNet to specify the modem
type or work with initialization strings. Like the standard serial port,
