each COM port and cabling distances should not exceed 50 meters (160ft).
1.4.4 Network connections
The terminal can be connected to one of the following communication networks:
Ethernet - For this type of communication, an IP address is defined for every terminal, enabling
communication with each terminal in TCP/IP protocol.
Bluetooth - For this type of communication, a pin number is specified, to authorize the connection.
