C (Inter Integrated Circuit) serial connection 

The ENC58 programmable encoder is equipped with a serial 
interface for the parametrization and set-up of the device. 
The serial interface is a I2C (Inter Integrated Circuit) type interface. 
To communicate with the encoder, you must connect the device to 
the personal computer through a USB port using the specific 
connection cable supplied  by Datalogic Automation upon request. 
The connection cable code is KIT ENC58. 
It is provided with a M23 12-pin female connector for the devices 
having ZCZ output circuit code; a M12 12-pin female connector for 
the devices having ZCM output circuit code; and a terminal for 
connecting the cable of the devices having ZCU output circuit code.
