Write down the replacement date on a sticker or label by adding 5 years to the date of installation. Then attach it to the bottom of the AXB-MIDI. FIG. 6 Lithium battery and socket All control commands in AXB-MIDI memory are lost when the lithium battery is replaced. Contact your AMX dealer before you replace the lithium battery and verify that they have a current copy of the Axcess program for your AXB-MIDI. This will avoid any inadvertent loss of data or a service outage. AXB-MIDI MIDI Interface 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. 7. rear Battery/socket front FIG. 7 AXB-MIDI circuit card, showing location of battery 1. Discharge the static electricity from your body. 2. Unplug all cables from the AXB-MIDI. 3. Remove the five pan-head screws on the top of the AXB-MIDI enclosure. 4. Pull the two enclosure halves apart and set the bottom portion of the enclosure on a flat surface. 5. Locate the battery on the circuit card. 6. Carefully pry the battery out of its socket and insert the new battery. Write down the next replacement date on a sticker or label by adding 5 years to the replacement date. Then attach it to the bottom of the AXB-MIDI. 7. Plug all cables back into the AXB-MIDI. 8. Place the top portion of the enclosure back onto the bottom portion. Then, refasten the five pan-head screws. 9. Reconnect the cables. There is a danger of explosion if you replace the battery incorrectly. Replace the battery with the same or equivalent type recommended by the manufacturer. Dispose of used battery according to the manufacturer's instructions. Never recharge, disassemble, or heat the battery above 212°F (100°C). Never solder directly to the battery or expose the contents of the battery to water. AXB-MIDI MIDI Interface Programming Programming Send Commands Send_Commands control AXB-MIDI signal routing by the Central Controller. The AXB-MIDI supports the Send_Commands described below. AXB MIDI Send_Commands Command Description INA Configure the destination for the incoming data on IN A (see the IN A and IN B Signal Routing table on page 8). Syntax: 'INA-' Parameter: = 0 to 7 Example: SEND_COMMAND ,'INA-5' Routes incoming IN A data to THRU output and to the Central Controller. INB Configure the destination for the incoming data on MIDI IN B.(see the IN A and IN B Signal Routing table on page 8). Syntax: 'INB-' Parameter: = 0 to 7 Example: SEND_COMMAND ,'INB-7' Routes incoming IN B data to THRU output, OUT output, and transmit data to the Central Controller. RXACLR Syntax: Clear characters waiting in 'RXACLR' the IN A receive buffer (to be Example: sent to the Central Controller, MIDI THRU, or SEND_COMMAND ,'RXACLR' MIDI OUT). Clears the IN A receive buffer of all contents. RXBCLR Syntax: Clear characters waiting in 'RXBCLR' the IN B receive buffer (to be Example: sent to the Central Controller, MIDI THRU, or SEND_COMMAND ,'RXBCLR' MIDI OUT). Clears the receive buffer contents for IN B. RXCLR Syntax: Clear all characters waiting in 'RXCLR' both receive buffers (to be Example: sent to the Central Controller, MIDI THRU, or SEND_COMMAND ,'RXCLR' MIDI OUT). Clears the receive buffers or all content for IN A and IN B. RXON Enable the ABX-MIDI to send received characters to the Central Controller. Syntax: 'RXON' This command is automatically sent by the Central Controller when a CREATE_BUFFER program instruction is executed. Example: SEND_COMMAND ,'RXON' Sends received characters from IN A and IN B to the Central Controller. AXB-MIDI MIDI Interface Programming AXB-MIDI Send_Commands (Cont.) Command Description RXOFF Syntax: The AXB-MIDI will not pass 'RXOFF' on received characters to the Example: Central Controller. This is the default. SEND_COMMAND ,'RXOFF' Turns IN A and IN B transmit to the Central Controller off. TXCLR Syntax: Clear all characters waiting in 'TXCLR' both transmit buffers (MIDI Example: THRU and MIDI OUT). SEND_COMMAND ,'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 ,'TXTHRUCLR' Clears THRU transmit buffer. TXOUTCLR Syntax: 'TXOUTCLR' Clears characters waiting in the MIDI OUT transmit buffer. Example: SEND_COMMAND ,'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 connector...
