The BatmouseIII IR-protocol document is intended for internal use at ASK. General data ( As BatmouseII ) Transfer rate: ( 2400Baud ) Bits: Stop bits: Parity: 8 1 Even Number of bytes in a packet Trackball: 3 Keyboard: 4 Time between packets Trackball: 64ms Keyboard: 130ms Carrier freq: 38KHz Packets Trackball packet: Source = 5 Target = 2 Source address: BatmouseIII Destination address: Projector Track Ball Byte0 = 0xAA Track Ball Normal Byte0 1 0 S2 S1 S0 T2 T1 T0 Byte1 0 X6 X5 X4 X3 X2 X1 X0 Byte2 1 Y6 Y5 Y4 Y3 Y2 Y1 Y0 Track Ball Extended Byte0 1 Sx - Source Addr, Tx - Target Addr X Movement, -64 to +63 Y Movement, -64 to +63 0 S2 S1 S0 T2 T1 T0 Byte1 0 X6 X5 X4 X3 X2 X1 X0 Byte2 1 Y6 Y5 Y4 Y3 Y2 Y1 Y0 Byte3 0 D6 D5 D4 D3 D2 D1 D0 * bits 6 - 0 * Byte4 1 C6 C5 C4 C3 C2 C1 C0 Sx - Source Addr, Tx - Target Addr X Movement, -64 to +63 Y Movement, -64 to +63 D6 - D3 Sense Pattern, D2 - D0 Drive Line number Checksum of Byte 0 - 3, NOTE: Make sure Byte1 & Byte2 make up to even parity! Keyboard packet: Source = 5 Target = 2 Source address: BatmouseIII Destination address: Projector Keyboard Packet Byte0 = 0xEA Keyboard Packet Byte0 1 1 S2 S1 S0 T2 T1 T0 Byte1 0 0 0 0 0 D9 D8 D7 Byte2 Byte3 Sx - Source Addr, Tx - Target Addr D9 0 = Key Released, 1 = Key Pressed D8 Key Press Packet Toggle-bit D7 Unused 1 D6 D5 D4 D3 D2 D1 D0 D6 - D3 Sense Pattern, D2 - D0 Drive Line number 1 C6 C5 C4 C3 C2 C1 C0 Checksum of Byte 0 - 2, bits 6 - 0 Calculate the Check Sum as follows: (0x7F & Byte0) + (0x7F & Byte1) + ... , then 2's comp. A key package might have three states: Key released, key pressed or key held pressed. D8 and D9 tell the state of the keypress. D8 toggles between consecutive packets when key is held down.
