In cases like e.g. the TestBook T1 – T3 , where the usage of an old serial Microsoft Mouse is indispensable when the TouchScreen has stopped working, it became difficut to obtain those old fashioned Hardware.
With this adaptor you can turn a modern optical USB / PS/2 mouse into an 100% compatible Microsoft Mouse to be used with your TestBook or any other vintage computer with a RS232 interface.
The adaptor needs a 5V or 12V supply voltage.
The adaptor is also offered in a version without mounted serial and PS/2 connectors, for direct connection inside a host system.
