4-5. Panel ID setting (USB mode)

If two (three or four) touch screens to the same host are connected simultaneously, each TSC-30/IC to the host needs panel ID setting. This function is enabled in the USB mode, by setting pin number 58 (JP4) and pin number 59 (JP5) to “H” or “L”. Setting is enabled when hardware is reset, where Device Descriptor’s

iProduct is set to “0” or “1” and this value is identified by the

 

VCC

 

host as panel ID.
