3. Connecting and configuring
3.1. Connecting
Only individuals with specialized technical training and who have studied the product specifications are
permitted to assemble (install) the modem.
Before connecting the device, install the SIM-card (mini SIM, 15x25mm) into the modem. In order to do
that:
Eject the SIM-tray by pressing the SIM-card tray ejector button (Fig.2.4.1)
Place the SIM-card into the SIM-card tray
Insert the SIM-card tray into the modem
Be careful when installing the SIM-card.
Connect the GSM antenna and the commuting USB or RS232 cable. The modem can be powered using
the USB cable. If needed the modem can be powered using the TJ6-6P6C power connector (see Fig. 2.5.2).
Note:
GSM antenna, the commuting cables and the power supply are not included in the set.
To use USB interface install a driver on your PC. The driver can be found at
www.irz.net
. After the driver is
installed, a modem will be added to the hardware manager.
After the SIM-card’s PIN-code is removed, the device is automatically registered online, which is indicated
by the green indicator blinking rapidly. Once the registration is completed, the modem goes into the operation,
after which the green indicator begins to blink less rapidly (see Table 2.6.1).
3.2. Control, rebooting, shutdown
Connection and configuration of the modem for Internet access from a PC is done in the same manner as
that of a standard modem. For industrial applications the control of the modem is done using standard AT-
commands. You can download the description of the AT-commands at
www.irz.net
.
The modem can be rebooted using one of the following ways:
Eight transitions of the DTR COM-port line into a passive state (DTR < -2V); the duration of the
impulses and pauses between the impulses should remain within the range of 100-500 ms;
Rebooting after a given period of time (WD interval, turned off by default), setting is done in the menu
mode;
by AT-command (AT+CFUN=1,1).
Temporary power shutdown.
