6 Connecting to a CTM-15X Modem Remotely

Please note:

It is highly recommended to test all device configuration and operation before deploying devices

to remote locations.

Not all wireless networks offer "public" IP addresses that are remotely accessible, some are

firewall protected to allow access from either the same IP pool only or restricted IP addresses.

Contact your wireless network provider or administrator to determine what options are available.

Some networks will force device IP addresses to change at regular intervals. Without proper

configuration, this could cause a remote device to become inaccessible if the device IP address is

not known. The CTM-15X can be configured to send a message when its IP address changes using

this command: cmd iocond

Embedded wireless radio modules must be activated before deploying to remote locations

Incorrectly configuring the device could cause the device to become inaccessible, take care when

issuing commands via a remote session.

There are 4 ways to configure a CTM-15X remotely:

Telnet (most flexible, allows access to the complete repository of remote commands)

Device Embedded Web Page (provides access to a limited sub-set of device commands, used

typically for quick configuration of basic commands)

SMS (Allows commands to be sent to the modem via SMS, this command only applies to devices

with embedded Sierra Wireless CDMA/EV-DO revision A cards,USB modems or modules)

ULCP (Allows configuration of digital outputs only using ULCP binary format)

For telnet to work with a remote device cmd rmttelnet 1 must be set.

For access to the Device embedded web page, cmd rmtweb 1 must be set.
