5.1 Address assignment for Ethernet
The reader is connected to Ethernet via the RF182C communication module.
Communication between the application in the PC (client) and the reader (via the RF182C as
server) only functions with a unique address assignment:
MAC-ADD
The physical address, MAC-ADD (Media Access Address), is defined by the manufacturer
for each RF182C.
Example MAC-ADD: 67-89-AB-CD-EF-01
You will find the MAC-ADD printed on the side of the RF182C.
IP address
In addition, each RF182C requires a logical address, an IP address (Internet protocol), which
is used to address it on the network.
An IP address may be present only once within a network. It must be parameterized in the
RF182C. In the user application in the PC, the IP address is specified when establishing a
connection.
The IP address always comprises 32 bits and is represented in decimal format (value range
from 0 to 255). It therefore comprises a string of four numbers in ASCII format which are
each separated by a point.
Example of an IP address: "157.163.170.12";
Subnet mask
The subnet mask is required to specify the network. The subnet mask is similar to the IP
address. It comprises four numbers which are each separated by a point (default value:
255.255.255.0).
Example of a subnet mask "255.255.0.0"
Socket
A socket is a communication end point that is defined by an IP address and a port.
