GPRS TCP/IP CONNECTION 

Through GPRS TCP/IP protocol, it is possible to interact with the data logger from a remote PC 
with an Internet connection.  
The connection can be of two types: 

1)

 

Data Logger = Client

 , 

PC = Server

 

The data logger acts as TCP client and requests the connection to the PC, the PC acts as 

TCP server and waits for the connection request. The server IP address (PC or Router) 

must be public and can be either static or dynamic; if the IP address is dynamic, it is 

convenient to register the server to a DDNS (Dynamic Domain Name System) service. 

2)

 

Data Logger = Server 

PC = Client

 

The PC acts as TCP client and requests the connection to the data logger, the data logger 

acts as TCP server and waits for the connection request. The server IP address (data 

logger) must be public and static. 

Connection Data Logger = Client , PC = Server 

1.

 

Open a port (port forwarding) in the Modem/Router through which your PC connects to 

Internet (follow the instructions of your Modem/Router). 

2.

 

Connect the data logger to a PC USB port and perform the connection procedure with the 
HD35AP-S software. 

3.

 

In the HD35AP-S software select 

Instruments setup >> GSM options >> GPRS TCP/IP client 

settings

 and set the server IP address or domain name and port number (number of the port 

opened in the Modem/Router). 

4.

 

Disconnect the data logger from the USB port. 

5.

 

In the HD35AP-S software select 

Tools >> Type of connection

, select the 

TCP server

 option 

and set the number of the port opened in the Modem/Router. 

6.

 

In the HD35AP-S software, select the 

Connect

 icon. 

7.

 

Send to the data logger the SMS command 

TCP-CLIENT-ON

If the connection is not established within 30 minutes after sending the SMS command TCP-
CLIENT-ON, the command must be sent again. 
Alternatively, the server IP address or domain name and port number can be set in the data 

logger without connecting the data logger to the PC and without the HD35AP-S software by 

using the SMS commands 

TCP-SERVER-ADDRESS

 and 

TCP-SERVER-PORT

Connection Data Logger = Server , PC = Client 

1.

 

Open a listening port in the data logger 

by using the SMS command 

TCP-LISTEN-PORT

 

(for example, TCP-LISTEN-PORT=2020). 

2.

 

Send to the data logger the SMS command 

TCP-SERVER-ON

3.

 

The data logger replies with a first SMS to confirm that the command has been accepted. 
Wait for a second SMS with the confirmation that the 

TCP server

 functionality has been 

activated and with the IP address (and port number) assigned to the data logger. 

4.

 

In the HD35AP-S software select 

Tools >> Type of connection

, select the 

TCP client

 option 

and set the IP address and port number of the datalogger. 

5.

 

In the HD35AP-S software, select the 

Connect

 icon. 

If the connection is not established within 1 hour after sending the SMS command TCP-
SERVER-ON, the command must be sent again.
