Controller Circuit Board The four channel PMT controller board is a PIC microcontroller based device that communicates with a PC by USB as an HID device and with a PIC-based “hand unit” via PIC-to-PIC RS-232 protocol. These two external inputs (USB and RS-232) send strings to the PMT controller that: * Sets the four high […]
