The network type interface is shown as below. See Figure 5-47.
Here we take the ATM/POS protocol to continue.
There are two types: with or without the protocol according to client’s requirements.
With the protocol
For ATM/POS with the protocol, you just need to set the source IP, destination IP (sometimes
you need to input corresponding port number).
Figure 5-47
Without the protocol
For the ATM/POS without the protocol, the interface is shown as in Figure 5-48.
Source IP refers to host IP address that sends out information (usually it is the device host.)
Destination IP refers to other systems that receive information.
Usually you do not need to set source port and target port.
