The
TO-PASS
®
modem GPRS RS-232 replaces a conventional AT-controlled
switched-line or dedicated-line modem. Applications can communicate with a
control center or with one another bi-directionally via GPRS. A TSC-capable
remote station is required for communication and establishing connections.
A serial RS-232 interface makes it possible to easily integrate this GPRS modem
into existing technical infrastructures.
Regardless of the operating system used by the application, the GPRS modem
uses TCP/IP networks for communication. Incoming and outgoing GSM/CSD
data calls are supported.
The
TO-PASS
®
modem GPRS RS-232 has two different operating modes:
• Terminal
mode
• GPRS
mode
The
TO-PASS
®
modem GPRS RS-232 is supplied from the factory with Terminal
mode activated.
The range of functions and mode of operation of the device differ in both modes.
Note
Switching between modes
Switching between GPRS mode and Terminal mode (see Section
"Switching Between Terminal Mode and GPRS Mode ") requires the device
to restart.
