Easson DRO Glass Scale Linear Encoder
Easson Low Cost Easy To Install ES-19 Embedded DRO With Linear Encoder | Rotary Encoder
Comprehensive Data Interfaces
Thanks to Easson's latest custom built processor DP-20, ES-19 offers very comprehensive choices of external interfaces for outside world connectivity, such as USB 2.0, UART ( 3.3 V ) , RS232C.
USB 2.0 and UART (3.3V) are standard embody interface, RS232C is optional purchase options.
Easson provides comprehensive and extremely simple API and programming examples source codes to help customers handle the ES-19 interfacing with computer or machine controller in shortest possible time.
ES-19 can work with any linear glass scale or rotary encoder which have output signal in standard digital A Qual B (TTL or RS422). digits output display can be in either length or angle selectable.
