Professional Interface Solution
The Array Electronic 3312 USB to TTL Adapter represents a purpose-built solution for modern computer connectivity to Array's professional test instrument range. This adapter eliminates the compatibility challenges faced when connecting Array 364X programmable power supplies and 371X electronic loads to contemporary computers lacking RS-232 serial ports.Signal Conversion Technology
The adapter employs robust signal conversion circuitry to translate USB protocol data into TTL-level serial communication. Unlike generic USB to serial converters, the 3312 is optimised specifically for Array instrument communication protocols, ensuring reliable data transmission and instrument response.TTL voltage levels: Logic 1 = 3.3V to 5V, Logic 0 = 0V to 0.8V
