Using the RS485 Connection Each amplifier is equipped with an RS485 connection. These connectors are linked internally, so if both amplifiers have the same AMP ADDRESS assignment, the Input Selection and MASTER VOLUME buttons track each other, since they are assigned to the same zone. One side must have AMP ADDRESS switch #6 in the Master position (up), and the other side in the Slave position (down). The same thing can be accomplished between two SP2400s by connecting the amplifiers together with the RS485 connection. Again, be sure that both amplifiers are assigned to the same zone (AMP ADDRESS switches 1-5), one is configured as Master and the other Slave, and that no other amplifiers are connected via the RS485 port with the same AMP ADDRESS. In this way, you can have one Remote control operate both amplifiers that are assigned to the same zone. Note: The microprocessor polls the AMP ADDRESS switch when it initializes at power-up. If a change is made to the AMP ADDRESS switch, turn the SP2400 off for five seconds, then turn it back on again for the new settings to take effect. Using the SPLinker Sound Palette Controller The RS485 connection can also be used to connect the SP2400 to a computer loaded with the SPLinker software application. The PC-compatible computer must have an RS485 port to properly connect to the SP2400. It may be necessary to install an RS485 interface card, or use an RS232 port with an RS232-to-RS485 converter. The SPLinker is a PC-based graphical interface to provide real-time monitoring and control for up to 32 zones. It provides individual program source selection and volume control for each zone. Select boxes are located at the bottom of each zone for selecting multiple zones. All selected zones can then be modified at the same time in the Multiple settings box located on the right-hand side of the screen. Using a 3rd Party Control System The RS485 connection can also be used to interface with common third-party control systems. Contact the third-party provider or Mackie Industrial Technical Support to determine if your control system is compatible with the SP2400. Upgrading the Software From time to time, Mackie Industrial will release upgrades for the internal operating software in the SP2400. This can be downloaded from our website (www.mackieindustrial.com) to a PC-compatible computer. Use the serial port on the computer to connect to internal connectors on the SP2400's CPU boards to transfer the data to the on-board flash memory. Instructions will be provided when upgrades are available. SP2400 - 22
