Single Chip Microcomputer System Touch Display Panel for Fly Online Laser Marking

YM-02 is a touch controller for online laser marking machine, which orders the laser to mark when material comes into the marking scope. It's usually used for marking expiration date, date of manufacture, QR code, bar code and brand. YM-02 can synchronize the speed of conveyor of produce line with the speed of laser, support positive and negative running direction. It's made up of two parts: the touch controller and the adapter board. Supports USB import vector documents.Control interface:DB25 Interface pin function of controlling laser sourceThis is a 25-pin D-SUB (female head) type, all the controlling PIN# are TTL signal, unless otherwise stated.  Pin#Describe1-8(D0-D7)Power set (16 Hexadecimal 0-FF, or 10 Hexadecimal 0-255) LSB (D0) corresponds PIN 1,MSB corresponds PIN8.- 00h (0): Min. output power.- FFh (255): Max. output power.-Without connection or don't use, equivalent to 00h.9Power on (Latch) rising edge is valid10-15,24Grounded16,21Laser source alarm status:Pin16Pin21StatusLLThe laser temperature has exceeded the operating temperature range.LHNormal statusHHMO abnormal18Main Oscillator (MO) Switch Signal:- H level: MO open- L or not: MO OFF19Laser modulation input (Booster amplifier on / off input)- H level: Booster open- L or not: Booster off20Pulse repetition frequency (synchronous) input is square wave.The specifications refer to the operating PRR range.
