Packet Service Connection Command; Session Timeout; Ping Interval; Source Port Starting / Ending Numbers - Honeywell CNI2 Operating And Installation Manual

Packet Service Connection Command

This command is issued to the cellular radio to request a packet (Internet) connection. For most
CDMA service providers the phrase "ATD#777" will work, and this is the default setting for the
CNI2 in CDMA mode.
If you are having problems connecting, this could be the problem. Contact your service provider
for more information.

Session Timeout

If there is no communications between the CNI2 and the data collection system for this many
seconds then the CNI2 will terminate the connection. Recommended value is 30 seconds.

Ping Interval

Not used in this application.

Source Port Starting / Ending Numbers

This only applies to packet (Internet) connections.

allowed access to the outside world. Most corporate computer systems use firewall technology
to prevent unauthorized and potentially damaging access from outside sources. To minimize
potential invasion DC-2009
the 64-bit data encryption standard (DES64). If this exchange fails, the connection is terminated
by both sides.
When the CNI2 calls in it assigns itself what is known as a "source port" number. To further
enhance security the CNI2 can be assigned only one or a specific range of source port numbers
that the firewall will allow through.
Valid source port numbers are 40000 – 65535. The CNI2 will use a new number with each call.
For example for a range of 50000 – 50010, the first call will use 50000, the 2
so on. When 50010 has been used the next port number will roll back to 50000.

PAP User Name and Password

As an added security measure some cellular service providers require Password Authentication
Protocol, or PAP, to gain access to their Internet service. The radio must present a user name
and a password that was assigned when the cellular service was purchased. The user name or
password can be any combination of printable characters, including spaces, such as "Bob
Smith" or "1234". The total number of characters for both the user name and password cannot
exceed 48 characters. Often the cellular provider has a specific format for the username and
password, so you will need to obtain that information from them.
The password is hidden on this screen for added security. You must enter the password twice
to verify that it was entered correctly.
