Ethernet star topology
The code reader is operated as a stand-alone single device in an Ethernet star topology with individual
IP address.
• The code reader is designed as an Ethernet device with a standard baud rate of 10/100 Mbit.
• A fixed MAC address is assigned to each device by the manufacturer; this address cannot be
changed.
• The device automatically supports the transmission rates of 10 Mbit/s (10BASE T) and 100 Mbit/s
(10BASE TX), as well as auto-negotiation and auto-crossover.
• The device supports the following protocols and services:
• TCP / IP (client/server)
• UDP
• DHCP
• ARP
• PING
• For communication with the superior host system, the corresponding TCP/IP protocol (client/server
mode) or UDP must be selected.
