4. In this document it refers to the port that Matrix connects to Suspend mode According to the USB 1 1 specification all devices should enter a suspend power saving mode upon 3msec of inactivity of the USB bus This includes the loss in communication With the Host or the Host Operation System disable the device etc Matrix will enter this suspend mode after doing the followings 1 Disable Matrix 2 Return any bill that is currently undertaking On exiting the Suspend Mode Matrix will be reset by the inherent USB Bus reset Any prior status setup will be cleared and back to their default stage Communication When the Host is not polling the Matrix for a time longer than 4 seconds Matrix will Time out return any bill held in escrow and will not take any bill Matrix is disabled Enumeration When an USB device is attached to the Hub the Host Operation System will start an enumeration process During this process information and capability of the device is sent to the PC The Host Operation System will determine whether or not to configure Page 2 of 7 Manual VTIUSB 1 Matrix USB Manual VTIUSB 1 Bus Address Sequence No the device and register as an active device depending on the existing resources available in the system The factors that may inhibit a device from being configured include the data bandwidth requested by the device the CPU usage of the system and the traffic already in the USB bus etc Only upon success

8. t the application program cannot see a real time upstream message sent from the device That is to say all the upstream messages sent from the device are stored to the bottom of the Host computer buffer Only by continual popping of the buffer will the latest message be able to seen by the program This leads to an unsynchronised situation in Matrix communication When the Host polls Matrix for the most current status the Host will always see the precedent message stored in the computer buffer The Host has to keep on retrieving the buffer messages until the last message pops up to the top of the buffer In MS Windows 98 this buffer has a fixed storage of 2 messages In MS Windows 98SE 2K Me the default number is 8 User can change this number with SetNumInputBuffers register To cope with this variance of Operating Systems Matrix incorporates with a message Sequence No to keep track of the messages This number is added to both the upstream and downstream messages for the detection of the correct sequence of the receiving message The Host will keep polling for the same command until the Sequence No received from Matrix is the same as the one sent out On the other hand Matrix will keep resending the same message until the Host changes the same Sequence No Page 3 of 7 Manual VTIUSB 1 Matrix USB Manual VTIUSB 1 2 2 DOWNSTREAM MESSAGE FORMAT Host to Matrix Format gt gt Cmd Byte Bill Field Data 1 Bill Field Data 0 Mode Bits Seq
