Wiring data interfaces
Wiring Ethernet interface (only Lector621 variant)
1.
Connect the device to the Ethernet connection of the computer via the adapter
cable.
2.
Set up communication via the SOPAS ET configuration software.
NOTE
The Ethernet interface of the device has an Auto-MDIX function. This automatically
adjusts the transmission speed as well as any necessary crossover connections.
Wiring the serial data interface (all variants)
The maximum data transmission rate for the serial interface depends on the length of
cable and on the type of interface. Observe the following recommendations:

NOTICE
Risk of damage to the internal interface modules!
If the serial data interfaces are wired incorrectly, then electronic components in the
device could get damaged.
