What to do before to install the SIM into instru-
ment’s modem
Check best signal coverage for operator choice.
Modem is compatible with the following GSM frequencies: 900
-1800 -1900 MHz (three-band). Not compatible with 3G only
operators.
SIM type is:
Mini-SIM (classica SIM card in uso nei telefoni)
Lenght 25 (mm) - Width 15 (mm) - thickness 0,76 (mm)
Subscribe to a data plan for monthly traffic activity of about 500MB
Make sure PIN REQUEST is OFF. If not insert SIM into a standard
mobile phone and disable it.
Several instruments are connected in RS485 mode
but the software displays only one
Make sure the termination jumper on the first and last instrument
of the chain are closed
The GPRS modem does not connect to the network
Verify the correct insertion of the SIM
Verify APN parameters and enter them
manually if necessary
Make sure the SIM has a data plan active for internet access
Make sure the provider supports international roaming DATA if the
connection is abroad
The instrument is unable to obtain a valid IP ad-
dress from the LAN or the software does not
connect to it
Make sure the pre-existing network allows auto-assignment of the
IP address (automatic DHCP); if it does not, contact the network
administrator to obtain the data to enter manually
Make sure the network cable is connected to the instrument. Make
sure it is a good quality cable and not the “cross” type.
CAT 5, 6 and 7 cable types are compatibles
ERMES does not find the instruments via internet
that are correctly connected to a LAN
Make sure the internet connection is active
Make sure there are no port-blocking third part programs and/or
firewalls active that prevent data traffic through the TCP 2020 port
