2.1 G 401 and G 402
6
GSM modem via Ethernet
6
6
The G 401 and G 402 are connected to a CU 401
6
control unit via an Ethernet cable. See cable specifi-
6
cation in section 12. Technical data.
6
The modem can function as a GSM modem, a GPRS
7
modem and send/receive SMS messages. The
actual function is determined by the application on
8
the CU 401.
9
For GSM data communication with e.g. a SCADA
10
system, both the COMLI and ModBus protocols can
10
be used. The application determines which protocol
10
to use in the actual situation.

2.2 G 403
11
Radio modem via Ethernet
11
11
The G 403 is connected to a CU 401 control unit via
11
an Ethernet cable. See cable specification in section
11
12. Technical data.

The modem is connected to the RS-232 port via a
14
cable. The actual function is determined by the appli-
14
cation on the CU 401.

2.3 G 404 and G 405
16
GSM modem via GENIbus
17
The G 404 and G 405 can be connected to a GENI-
17
bus network to communicate via a GSM modem.
17
The modem can function as a GSM modem, a GPRS
modem and send/receive SMS messages. The
actual function is determined by the application on
the G 404 or G 405.
For GSM data communication with e.g. a SCADA
system, both the COMLI and ModBus protocols can
be used. The application determines which protocol
to use in the actual situation.
2.4 G 406
Radio modem via GENIbus
The G 406 can be connected to a GENIbus network
to communicate via a radio modem.
The radio modem is controlled via an RS-232 port.
