Controlling the JBL Professional DSC260 System Controller Using SIA-Smaart Pro revision 1, 8/99 — Page 2Once you have obtained the necessary software and cable, follow the steps below to upload the newprogram to the DSC260.Step 1: Connect the DSC260 to your computer.Connect the serial port (labeled RS232) on the rear panel of the DSC260 to a serial (COM) port on yourcomputer using the null modem cable. If the Boot version number (the number beginning with “B” displayedon the DSC260’s front panel display on power up) is B0.13 or later you can skip to Step 2 below. Ifthe Boot software is B0.12 or earlier then you will have to disconnect the DSC260’s power cable andreconnect it while holding down the Recall and Mute4 keys. The unit will step through an led test patternon power up then display a message similar to:OK 0000000 Check:D993The DSC260 is now waiting for the PC software to run.Step 2: Uploading the new program.Double-click on the file 626loadr.exe to start the flashloader application. If the path and file name for the newfirmware file (626v105b.a21 or later) is not alreadyentered in the Transfer File field, click the Browsebutton, select the file you want to upload and click OK.Now select the number of the computer’s serial portyou connected to the DSC260 in the From Comm Portfield, select the All option in the To MIDI Channel field,and click the Go button.The DSC260 will display the message Running Loader.. and the loader program will indicate theprogress of the file transfer by displaying the percentage sent as the file is uploaded. The DSC260 willrestart when the transfer is completed and display the following message:JBL DSC 260B0.1x UpdatedThe DSC260 should now be enabled for remote control through MIDI or serial connection (using the nullmodem cable) from Smaart Pro. You will need to configure an External Device definition and select theproper serial port or MIDI channel in the Real-Time module as you would any other supported externaldevice.Note: Depending on how you have Windows’ file display options set on your computer, 626loadr.hlp and626loadr.exe may both appear as just "626loadr" in file folder windows. You can tell which is which by theicons used to represent the file type (the help file will be the one with the book icon).Making Control ConnectionsIf you want to control the DSC260 via serial connection, use the same setup you used to upload the newfirmware program. To control the DSC260 via MIDI connection from your computer, the computer mustbe equipped with a Windows-compatible MIDI I/O hardware interface — typically a joystick-to-MIDI

MIDI connectionsbetween the computer and the EQ are made with outputs to inputs and inputs to out puts as in the figurebelow. An advantage to using a MIDI connection is that up to 16 units can be connected together in a“daisy chain” and controlled from a single MIDI port on the computer. The two figures below show connectiondiagrams for MIDI control of a single DSC260 and a chain of two or more units.ComputerJBL DSC260ComputerTwo (or more) JBL DSC260sMIDI InMIDI OutMIDI In MIDI Thru MIDI OutMIDI InMIDI OutMIDI In MIDI Thru MIDI OutTo MIDI Mixer orSwitcher (Optional)To MIDI Mixer orSwitcher (Optional)MIDI In MIDI Thru MIDI OutOn the left is a single DSC260 connected to a computer for MIDI control.The figure on the right illustrates a “Daisy-chain” of 2 (or more) DSC260s.Up to 16 DSC260s can be controlled from one computer MIDI port.Configuring the DSC260 in Smaart ProOnce the physical control connections are made, each DSC260 youwant to control through Smaart Pro must be configured as an externaldevice in the Real-Time module. The first step is to add a devicedefinition for each unit.Start Real-Time module and click the External Device Infobutton (shown at the left) on the top toolbar or select ExternalDevices from the Options menu to open the External DeviceInformation dialog box. Click the Add button at bottom left of thedialog box window. When the Add External Device dialog popsup, select “JBL DSC260” from the drop down list and click OK.A device definition for a DSC260 is created and the JBL DSC260Configuration dialog box (shown on the right) opens automatically. Inthis dialog box, you need to select the audio I/O mode (2-Channel 3-Way, 3-Channel 2-Way, or Mono) and the PC serial (COM) port orMIDI channel number you will use to control this device. If you areusing a MIDI connection, the MIDI channel selected here must matchthe MIDI Channel number set on the DSC 260 itself (using the front panel controls). When multipleDSC260s are chained together you will need to add a new device definition for each unit in the chain andthe MIDI channel setting for each unit must be unique.The Device Name appears only on the list of configured (physical) devices in the External Device Informationdialog box and in the System Controllers list in Delay Locator mode. The Other Names section iswhere you set the output channel names you want to appear in the drop-down lists of available deviceson the external control panel and in the System Presets dialog box. You can choose which channels willappear in these lists by checking or un-checking the “Show in drop-down lists” box next to each of the sixoutput channel name fields. For example, if you were operating this DSC260 in a “stereo linked” configuration,you might want to see only “master” channels listed and would leave “slave” channels unchecked.
