The ZD-Shifter SU12 is an all-in-one shifter, which includes 12 RS232 ports. It is designed to convert UART TTL signals to RS232 and USB Port to UART TTL Signals/RS232 both bidirectionally. Just with one input and output connector on ZD-Shifter SU12, users can convert signals of main unit of cars or test benches from one side and a datalogger on the other side.

As an efficient and convenient shifter, ZD-Shifter SU12 has multiple application scenarios. It can not only support the bidirectional signal transmission between 8 x TTL and 8 x RS232 Serial ports, but can also convert signals from 8 x TTL and 4 x RS232 to USB Ports in both direction. Depend on different test requirements, all these scenarios can take place simultaneously or separately.


The ZD-Shifter toolset software illustrates mapping relationship of all virtual COM ports in Windows to ZD-Shifter TTL and RS232 ports. Connecting the PC with one equipped USB cable, which supports all 12 RS232 ports, users can test and manage all 12 ports in an overview within the software conveniently.

Moreover, the onboard LEDs of the ZD-Shifter SU12 indicate the usage of the serial ports of the device, making signal conversion and test processes both user-friendly and efficient.
