Introducing the MP 595 Modem
Special MP modem modes such as GPS that are supported on
a serial port are also available on the virtual port. For example,
with the virtual port enabled, a mapping application on your
computer that normally listens for GPS messages on a serial
port listens for those same messages on the virtual port.
The MP modem virtual serial port is available on both USB
and Ethernet interfaces. For information on enabling a virtual
serial port, see the MP 3G Modems AT Command Reference
(document #2130810).
VPN support for RNAP
This feature allows for the exchange of Remote Network
Access Protocol (RNAP
1
) data between the MP modem and a
remote server accessible only through a Virtual Private
Network (VPN) connection. When using this feature, you must
have 3G Watcher running on the computer.
The MP modem sends RNAP data over Ethernet or USB to 3G
Watcher on the computer. 3G Watcher places the RNAP data in
a User Datagram Protocol/Internet Protocol (UDP/IP) packet
and sends it over the VPN connection to the server. When 3G
Watcher receives a UDP/IP packet containing RNAP data over
the VPN connection, it disassembles the packet and sends the
RNAP data to the MP modem.
You can enable this option using 3G Watcher software or AT
commands. See the 3G Watcher online help and the MP 3G
Modems AT Command Reference (document #2130810) for
details.
Software
The MP modem comes with the following software:
•
3G Watcher, the software for the MP modem which allows
you to manage and monitor your connections.
•
The driver that forms the interface between the MP
modem and your Windows operating system.
•
The firmware that is stored in non-volatile memory.
The MP 595 modem has an embedded radio module (a
Mini Card 5725), also made by Sierra Wireless, Inc. There
are two firmware programs on the MP 595 modem—one
1. RNAP is a Sierra Wireless proprietary protocol that encapsulates the
MTP data that is sent to and from the MP modem. It ensures that the
MP modem and remote host alike recognize the data packets. See The
Monitoring and Tracking Protocol Guide on
