Introduction to Serial Port Operation Modes

4.
Connecting TCP client and TCP server within the same cellular service provider.
In order to connect properly, the IP addresses of the two OnCell devices must belong to the same
subnetwork. To ensure that this is the case, use the same cellular service provider to connect the devices
to the network. In addition, you will need to request that the cellular service provider provide you with two
private IP addresses (e.g., 192.168.1.1 and 192.168.1.2).
TCP Client Modes
In TCP Client mode, the OnCell G3111/G3151-HSPA can actively establish a TCP connection to a pre-defined
host computer when serial data arrives. After the data has been transferred, the OnCell G3111/G3151-HSPA
can automatically disconnect from the host computer by using the Inactivity time settings.
As illustrated in the figure below, data transmission proceeds as follows:
(1) The OnCell G3111/G3151-HSPA, configured for TCP Client mode, requests a connection to the host.
(2) Once the connection is established, data can be transmitted in both directions between the host and the
OnCell G3111/G3151-HSPA.
Types of TCP Client Connection
1.
TCP Client to PC’s IP address.
The OnCell G3111/G3151-HSPA will only be able to connect to a host PC if the PC is using a public IP
address.
