Services Configuration
Rev 1 Oct.13 163
This is the IP address of the attached local host that is used as the destination
for all incoming Gateway messages.
5. Enter the Local Host Port.
This is the UDP port the destination host listens to for incoming messages.
6. Enter the ALEOS port.
This is the UDP port on which the AirLink device listens for outbound Gateway
messages sent from any local host.
Message Format Configuration (Only applies if you selected Ethernet in the
SMS destination field)
7. In the Start field, enter the start of message delimiter, or use the default
(<<<).
8. In the Field Delimiter field, enter the delimiter to be used between fields in the
SMS message, or use the default (,).
9. In the End field, enter the end of message delimiter, or use the default (>>>).
10. In the ACK field, enter the desired acknowledgment message, or use the
default (ACK).
ALEOS provides a message acknowledgment on every SMS message when
it is passed to the radio. If ALEOS does not send an ACK, wait for 30 seconds,
and then retry.
11. Click Apply.
Sending an SMS Command
The format for sending an SMS command in Gateway Only mode is:
[PW] [Prefix][Command]
Example:
“PW 1234 &&&reset”, where:
• 1234 is the password (required)
If you did not create a password when you configured SMS, use the default
password—the last 4 digits of the SIM number (for SIM-based devices) and
the last 4 digits of the ESN (for non-SIM devices). If you do not know the SIM
ID or ESN number, you can find it in ACEmanager in Status > WAN/Cellular.
• &&& is the prefix (required)
Use the default prefix (&&&). The prefix is not configurable in Gateway Only
mode.
• reset is the command
For information on sending SMS commands and a list of available commands,
see page 377.
Sending a gateway message
The AirLink device acts as an IP gateway to send non-command SMS messages
(gateway messages) as UDP packets from a locally-connected host to a
configured ALEOS port. The UDP packet must contain the SMS protocol-
formatted message.
