5 Connecting Encoder
5.1 Connection between PC and encoder
To realize the simplest possible connection to the PC, the encoder is equipped with an RS232 
interface. With this the encoder can be connected directly to the PC. If the transfer distance is 
greater than 30 m, it is advisable to use the RS485 interface. In this case an interface 
converter with an automatic directional switchover function is required on the PC (not included 
in the delivery scope). 
 
5.1.1 Encoder programming connection 
To program the encoder via a PC, the wires TxD, RxD and GND must be connected as
