ZD Shifter SU Series

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

Application Scenario

ZD Shifter SU4

Level conversion and online communication monitoring

Suitable for bi-directional signal transmission between up to 4 TTL and 4 RS ports, also capable of forwarding bi-directional communication signals to a USB port. The blue part of the diagram shows the bi-directional signal transmission between TTL and RS ports, while the user's computer can simultaneously view the real-time serial communication content between the vehicle terminal and the data recorder via the USB Type-C connection.

USB device for bi-directional TTL communication

The computer communicates with the TTL device via USB in bi-directional way, and can perform device serial port debugging.

ZD Shifter SU8

Level conversion and online communication monitoring

Suitable for bi-directional signal transmission between up to 8 TTL and 8 RS ports, also capable of forwarding bi-directional communication signals to a USB port. The blue part of the diagram shows the bi-directional signal transmission between TTL and RS ports, while the user's computer can simultaneously view the real-time serial communication content between the vehicle terminal and the data recorder via the USB Type-C connection.
