1 Description of the GSM modem
1.1 Description
The PSI-MODEM-GSM/ETH GSM modem is a high-performance modem for industrial
Ethernet networks, which can be used to transmit sensitive data securely via GSM
networks. The integrated firewall and the VPN support (Virtual Private Network) protect your
application against unauthorized access.
Remote stations can be integrated into an IP network via a GPRS/EDGE connection or by
dialing the phone number. The quad band technology means that the modem can be used
globally in all 850, 900, 1800, and 1900 MHz GSM networks.
No matter where your system or controller is located – the process data is available at any
location via a secure VPN connection.
For reliable and safe communication, the focus is on EMC, electrical isolation, and surge
protection.
In addition, the GPRS/EDGE service and GSM network quality are monitored. If necessary,
a corresponding message is sent or the GSM connection is reestablished.
Features
– Quad band (850 MHz/900 MHz/1800 MHz/1900 MHz)
–GPRS(General Packet Radio Service) and EDGE (Enhanced Data Rates for GSM
Evolution)
– Integrated TCP/IP stack
– Virtual permanent line for connecting networks via GPRS
– Integrated firewall
– VPN support
– Wide supply voltage range of 10 V DC to 30 V DC
– Temperature range of -25°C to +60°C
– High-quality electrical isolation (VCC // Ethernet)
– Integrated surge protection
– Easy configuration via web-based management (WBM)

•Connect a suitable antenna to the antenna connection.
•If the "NET" LED indicates good (flashing) or very good reception (steady light), secure
the antenna.
Installing the antenna
•Select an antenna position with a good wireless network signal. The "NET" LED can be
used to determine the receive quality.
•When using the PSI-GSM-900/1800-ANT antenna (Order No. 2708902), drill a hole
measuring 16.5 mm in diameter in the top of the control cabinet.
•Secure the antenna using the washer and nut provided:
Figure 2-5 PSI-GSM-900/1800-ANT antenna installation

2.4.4 Inserting the SIM card
Figure 2-6 Opening the housing
Opening the housing Open the housing to access the SIM card holder inside.
•Using a screwdriver, lever off the LAN connection cover.
Inserting the SIM card Your GSM service provider will have supplied you with a SIM card where all the important
data for your connection is stored.
•If you have been supplied with a SIM card in credit card format, simply detach the small
section of the card and remove any excess plastic from the edges.
•With the contact surface facing the PCB, slide the SIM card into the holder. The angled
corner should point upward (see Figure 2-6).
PIN code The SIM card can be protected with a 4 or 5-digit PIN code.
When selecting the SIM card, please note that a packet data connection (GPRS or EDGE)
is required for the core functions (VPN router).
WARNING: Disconnect the device power supply before replacing the SIM card.
The device only supports 1.8 and 3 V SIM cards. For older SIM cards, please contact your
GSM service provider.
NOTE: Electrostatic discharge
The module contains components that can be damaged or destroyed by electrostatic
discharge. When handling this module, observe the necessary safety precautions against
electrostatic discharge (ESD) according to EN 61340-5-1 and EN 61340-5-2.
