§ Connection with Host
Coordinate data, correction value or other various output data are all output to the host as a response
to IN token. Output coordinate in coordinate data mode and correction data mode is output in the
interrupt transfer, while other data is output to the host with control transfer.
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 host as panel ID.
