1.4.2 How to connect the Universal Mobile Modem SH2UMMF124
The Universal mobile modem SH2UMMF124 module is no longer available: it is mentioned here only to
understand compatibility with the past.
The installer has to perform the following steps to install the SH2UMMF124 modem:
1. Connect the SH2UMMF124 to the left of the Sx2WEB24 controller;
2. Insert the SIM into the SH2UMMF124 modem through the special slot. Make sure the
SIM is
not protected by a PIN code
(should that be the case, disable the protection);
3. Connect the antenna;
4. Connect the 24VDC power supply;
5. Configure it by means of the Sx tool software.

Recommendation:
Place the modem where there is good signal reception: this can be checked by connecting to the Sx
tool: at the bottom of the user interface there are 5 bars that indicate the field strength, as shown in the
example in the picture below.
N.B. Since the USB port used by the dongle modem is the same as the one used by the USB key
in the Sx2WEB24, the USB key cannot be used if the modem is already connected.
