Socket Retry Time: This is the time in seconds to wait between address retries to open a TCP socket connection.
The default value is 15 seconds. This gives the modem sufficient time to recover in case of signal drops or other
temporary connection problems.
Socket Inactivity Timeout: This is the time in seconds to retry socket connection in case of data inactivity over the
socket connection. The default value is 600 seconds = 10 minutes. You may want to modify it to a higher or lower
value according to the polling period of the attached device (maximum 18 hours). For example, if an attached slave
device is polled every 15 minutes by a master device then you need to set the socket inactivity timeout to a value
greater than that (say 910 seconds). To disable, set to Zero.
Note: Each time the inactivity timeout occurs, the modem will disconnect and re-connect the socket in an attempt to
recover the connection. This may incur a service charge from your operator, so it is important to ensure that you do
not leave the modem powered with no activity when the inactivity timeout is enabled.
SMS Settings
:
This is where all messaging related setting like
phone numbers, short messages etc are
defined.
SMS on successful Initialization: Enable this
setting if an SMS is needed on the successful
initialization of the 605M-D1 modem when it
gets into the automated connection mode. The
text box can be used to modify the default
outgoing message. The module name is
automatically appended to the message for
easy identification by the operator. For
example, this setting is very useful when
“Remote SMS Reboot” is enabled to get an
indicative SMS that the modem has actually
rebooted and commenced automated
connection.
SMS on socket Failure: This setting is used to
enable/disable SMS warning after the set
number of socket connection retries have
failed. It is enabled by default (recommended).
If it is disabled then no SMS will be sent out to
the operators on connection failures. The text
box can be used to modify the default outgoing
message. The module name is automatically
appended to the message for easy
identification by the operator.
SMS Retry: The number of times the 605M-D1 modem will retry to send the messages in case of failures.
Total Number of SMS Sent: If Remote SMS Reboot is not enabled then the 605M-D1 modem is designed to
repeatedly retry connection after the failure SMS has been sent. This setting is used to set the maximum number of
SMS that will be sent out per phone number after which any further SMS sending is stopped. This avoids sending out
endless SMS messages to the operators on every repeated failed connection attempt and provides a SMS capping
mechanism for significant cost savings.
Phone Number 1: Enter the phone number of the operator that gets the enabled SMS messages. Please follow the
same numbering format as you would use to send SMS through any other GSM device (mobile) in that area.
Phone Number 2: Same as phone number 1 this setting can be enabled to send SMS to a second operator.
Phone Number 3: Same as phone number 1 this setting can be enabled to send SMS to a third operator.
Remote SMS Reboot: This setting can be used to enable/disable the remote rebooting of the 605M-D1 via an SMS
message. The text box can be used to modify the trigger string (case insensitive). When this setting is enabled, the
modem will wait for an SMS message containing the reboot trigger string indefinitely once the number of socket
connection retry has failed. If the SMS on Socket Failure is enabled then an indicative string “SMS reboot enabled” is
also appended to the outgoing SMS message. This is useful to remind operators on connection failures that the
605M-D1 modem can be rebooted by sending an SMS to it. As an example, this setting is especially useful in
