NOTICE
SWIO3 and SWIO4 as switching output!
Ä
Do not operate pins 2 and 4 as switching output if sensors which function as switching input
are also connected to these pins.
ð
If, for example, the inverted sensor output is connected to pin 2, and pin 2 of the code
reader is, at the same time, configured as a switching output (and not as a switching in-
put), the switching output malfunctions.
RS 232/RS 422 interface
The RS 232/RS 422 interface is used primarily for outputting the read and decoded code contents of the
activated code types.

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
• ARP
• PING
