6. Coin Meter counts Refer to Overlap Counts for overlapped solution If this is the case Busy signal and Coin Meter may not reflect the real situation of the hopper User should use caution when designing his system Always contact your hopper manufacturer for the correct disc size Rotate disc slot too big for small coins causing coin overlap Overlap counts IPC provides a coin overlapping counter for each hopper ports to detect number of possible coin overlaps This is carried out by a time comparator comparing the average coin exit time and any sudden change If a longer exit time frame exists there may be two or more small coins overlapping or cascading together in one disc slot This will fool the Coin Exit Sensor resulting in a wrong Coin Meter counts Coin Exit Sensor Overlap counts 2 Possible overlap Possible overlaps This counter gives the number possible wrong time frames during dispensing Use Coin Meter Reset or Hopper Reset to clear counter Copyright Moneyflex Technologies LLC 2008 Page 9 of 16 or Moneuflex Technologies IPC 3 User Manual Version 1 2 Jun 19 2008 3 3 Controller 25 hex Analog inputs This Controller provides 4 analog ADC inputs Each ADC is an analog to digital converter providing a 8 bit resolution dividing 5VDC into 255 steps Thus each step equals 0 0196VDC In theory accuracy is close to 0 0049VDC But user should take account for power white noise and input impedance

MCU has a number of different Controllers built into it The Controller is the working unit that user is dealing with When user is talking to IPC he is actually talking to an individual Controller by using the K Protocol The protocol enables user to specify which Controller the message is directed to Only the intended Controller with a correct ID number will reply to the request On top of that there is a set of global commands that all Controllers will response to Each Controller has its own firmware known as the kernel The kernel version can be retrieved by user at anytime in his application By checking the kernel version user can know the updated information about that particular Controller The USB controller used in IPC is a USB 2 0 full speed chipset conforms to USB 2 0 standard set by USB IF Its main function is to inter connect all MCUs reside within the device and distribute user commands to from the PC and Controllers 2 1 KERNEL UPGRADE Controllers kernel is flash ROM based Occasionally MFX will release a new kernel version for a particular controller for new features This kind of upgrade can only be conducted at MFX appointed service site Any attempt to tamper with the kernel program will lead to unit malfunction and void all watranties 2 2 PC INSTALLATION The procedure of a PC OS eg Windows registers a USB device and gets it ready for use is called Enumeration When a USB device plugs in to a USB port OS receive
