6. USB interface
You can use HSDPA or GPRS internet access or CSD connection when connecting
Your EasyGate UMTS DATA with PC via USB interface.
6.1. USB interface drivers instalation
It is needed to install USB modem drivers for properly function of USB interface.
When the gateway is connected with PC for the first time the Windows operating system
will find automatically the new hardware. Choose the Find drivers in PC option and set
the drivers’ directory path. The modem drivers are on included CD in directory
Data\EasyGate\Modem driver. First You need to unzip the file
3G USB Modem
Drivers.zip
on Your hard drive. Choose to install drivers anyway when warning “driver’s
manufacturer is unknown” or “the driver is not signed” appears. You should install
drivers for the following devices:
-
Telit HSDPA USB Modem
-
Telit Diagnostics Interface
-
Telit Auxiliary Port
All this devices can be found in windows device manager (in Modems section and
Ports (COM and LPT) section). If the Windows function of automatically hardware
changes finding is disabled open Windows device manager, find new hardware without
drivers (marked with orange exclamation mark), click on it with right mouse button and
choose install driver options. Follow the instructions up to install drivers for all three
interfaces.
6.2. Connection settings and start
For internet connection create new telephone modem connections using Telit
HSDPA USB modem. Set up the modem using information from Your mobile operator.
6.3. Combination of USB traffic with voice calls
When using HSDPA internet access the voice calls are not affected. You can use the
gateway for HSDPA connection and voice calls at the same time. When using GPRS
connection the gateway is not accessible for incoming calls, outgoing calls interrupt the
GPRS connection. After call ends the GPRS connection is renewed.
7. COM – Serial Interface
The complete serial interface RS-232C on a 9-pin connector is identical with any
external modem.
The transmission rate is 115200 bps. Do not change it. (EasyGate UMTS Data
doesn’t supports autobauding.). The transmission setup must be 8 bits, no parity and
one STOP bit (8N1).
EasyGate UMTS Data’s central processor uses the same interface for establishing
calls and so it must have the possibility to block an external serial interface-all PC SW
must provide transmission hardware flow control (HW handshaking). COM can be used
for EasyGate UMTS Data programming
