ZD-Shifter SU Series

The need for level conversions is very common in many electronic systems. However, in the automotive sector, there are few products that can meet the requirements for bidirectional conversion of TTL and RS signals. The ZD-Shifter SU Series, a proprietary development by ZD, supports bidirectional signal level conversion for up to 8 TTL and 12 RS channels, ensuring the connection of on-board TTL communication and test computers in vehicles.

Features

Connection to devices via USB port
Connects to devices via the computer’s USB interface and performs multi-channel TTL and RS signal conversion while monitoring bidirectional data communication
Standard TTL level specifications
Complies with industry standards of 1.8V/2.5V/3.3V/5V
Integrated LED indicators for intuitive status display
Power supply
Uses a 5V USB desktop power supply or direct 12V power supply for automotive applications
Automatic sleep and wake-up function
Monitors communication to prevent power supply issues by automatically entering sleep and wake-up modes
Compatible with Windows and Linux operating systems
Multiple interface designs, supporting up to 8 TTL channels and 8 RS232 serial interfaces for bidirectional signal transmission
Port detection tool for easy port mapping display

Application Range

ZD-Shifter SU4
Designed for signal conversion and online communication monitoring
The ZD-Shifter SU4 is suitable for bidirectional signal transmission between up to 4 TTL and 4 RS ports. It can also forward bidirectional communication signals to a USB port. The blue section of the diagram illustrates the bidirectional signal transmission between TTL and RS ports, while the real-time serial communication content between the vehicle terminal and the data recorder can be simultaneously displayed on the user's computer via the USB Type-C connection.
