2.1 Function Overview
The INSYS GPRS 5.1 serial is a DIN rail device for industrial applications.
It has a compact design, a robust plastic housing and offers the following charac-
teristics:

Quadband GSM engine for all four frequency ranges: 850 / 900 / 1800 / 1900
MHz (The INSYS GPRS 5.1 serial can be used worldwide)
Before using the INSYS GPRS 5.1 serial you should check the certifica-
tion requirements in the country of deployment.

Integrated TCP/IP and PPP stack for transparent modem emulation via GRPS
(GRPS modem emulation)

GSM services: GSM/CSD data connection, SMS, GPRS Class 12, EDGE Class 12

Support for the virtual COM port driver VCOM from INSYS icom

Integrated TCP/UP stack for modem-compatible behavior with transparent
transfer of data from and to the serial interface (“TCP transparent”).

Active dialing of IP addresses or domain names with TCP connections to a
server

Accepts TCP connections ("TCP Listen")

Dedicated line function (leased line); design as CSD or TCP/IP possible; intelli-
gent re-dialing time-outs for TCP/IP cost cutting; configurable substitute ac-
cess for redundant paths.

Callback function for incoming calls; callback as CSD or “TCP transparent" pos-
sible

Defined termination of GPRS connections for incoming CSD calls ("CSDPRIO")
 Access protection via phone number analysis (CLIP) for incoming CSD calls, in-
coming SMS, when starting a callback, and when the priority for CSD calls is
set.
 Password protection for remote configuration and configuration via SMS

Storage of the SIM card PIN enables automatic login into the GSM network af-
ter reset/restart
 Timer-controlled logout and login into the GSM network or restart of the de-
vice, to prevent undefined login states in the GSM network

Automatic dispatch of a predefined SMS when the switch input is activated.

Advance switch input functionality: Connection setup and "IO tunneling"
(transmitting the input states via a TCP connection)
 Standard AT command set according to GSM 07.05 and GSM 07.07

Extended AT command set (INSYS AT command for additional functions)
