Hello, I am wondering what the electrical specifications of the UART on the tool port are. Specifically the required voltages for operation (For example, is it microcontroller based, running at 3.3V or 5V).
Thank you,
Karsten
Hi Karsten,
Tool I/O is bidirectional differential RS485. Common mode voltage is around 1.7V.
You need proper differential transceiver on the other side to go back to single ended logic levels.
Thank you for the fast reply, this answers my question!
