[. . . ] This will avoid any inadvertent loss of data or a service outage. AXB-MIDI MIDI Interface 5 Installation Static electricity can damage electronic circuitry. Before removing the lithium battery from the enclosure, discharge any accumulated static electricity from your body by touching a grounded metal object. You will need a flat-blade tool (non-conducting) that can be slipped under the lithium battery to pry it up and out of the socket. The location of the Lithium battery on the circuit board is shown in FIG. RXACLR Clear characters waiting in the IN A receive buffer (to be sent to the Central Controller, MIDI THRU, or MIDI OUT). RXBCLR Clear characters waiting in the IN B receive buffer (to be sent to the Central Controller, MIDI THRU, or MIDI OUT). RXCLR Syntax: 'RXACLR' Example: SEND_COMMAND <device>, 'RXACLR' Clears the IN A receive buffer of all contents. Syntax: 'RXBCLR' Example: SEND_COMMAND <device>, 'RXBCLR' Clears the receive buffer contents for IN B. Syntax: Clear all characters waiting in 'RXCLR' both receive buffers (to be Example: sent to the Central SEND_COMMAND <device>, 'RXCLR' Controller, MIDI THRU, or MIDI OUT). Clears the receive buffers or all content for IN A and IN B. RXON Syntax: Enable the ABX-MIDI to send 'RXON' received characters to the This command is automatically sent by the Central Controller when a Central Controller. CREATE_BUFFER program instruction is executed. Example: SEND_COMMAND <device>, 'RXON' Sends received characters from IN A and IN B to the Central Controller. AXB-MIDI MIDI Interface 7 Programming AXB-MIDI Send_Commands (Cont. ) Command RXOFF The AXB-MIDI will not pass on received characters to the Central Controller. TXCLR Description Syntax: 'RXOFF' Example: SEND_COMMAND <device>, 'RXOFF' Turns IN A and IN B transmit to the Central Controller off. Syntax: Clear all characters waiting in 'TXCLR' both transmit buffers (MIDI Example: THRU and MIDI OUT). SEND_COMMAND <device>, 'TXCLR' Clears THRU and OUT transmit buffers. TXTHRUCLR Clear characters waiting in the MIDI THRU transmit buffer. Syntax: 'TXTHRUCLR' Clear characters waiting in the MIDI THRU transmit buffer. Example: SEND_COMMAND <device>, 'TXTHRUCLR' Clears THRU transmit buffer. TXOUTCLR Syntax: 'TXOUTCLR' Clears characters waiting in the MIDI OUT transmit buffer. Example: SEND_COMMAND <device>, 'TXOUTCLR' Clears OUT transmit buffer of all contents. IN A and IN B MIDI Signal Routing The following table shows all routing value possibilities for IN A and IN B incoming MIDI signals in relation to the AXB-MIDI rear panel connectors. The value determines where the IN A and IN B MIDI signals will be routed. IN A and IN B Signal Routing Value 0 1 2 3 4 5 6 7 X X X X X X X X X X X X THRU OUT AXlink The power-up default value is 3. Inputs are controlled as Channels 1 through 8. 8 AXB-MIDI MIDI Interface Programming MIDI Programming Most MIDI command strings consist of a status byte followed by one or two data bytes. The most notable exception to this is the System Exclusive which starts with a status byte of $F0, has 4 or more data bytes, then ends with a status byte of $F7. [. . . ] · Used to terminate a System Exclusive dump (see above). 11110011 · 0sssssss 12 AXB-MIDI MIDI Interface Programming The following table lists and describes System Real-Time Messages: System Real-Time Messages Status (D7---D0) 11111000 Data Bytes (D7---D0) Description · Timing Clock. · Sent 24 times per quarter note when synchronization is required. · Start the current sequence playing.
