Troubleshooting 261 Troubleshooting DME32 Symptom Advice Cannot turn on the DME32. Cannot establish communication between the DME32 and DME Manager. Cannot select a configuration memory for recalling. Make sure that the power cord is connected to a suitable AC wall outlet. See "Connecting the Power Cord" on page 11 for more information. Make sure that the DME32 POWER switch is set to the ON position. See "Turning On & Off the DME32" on page 11 for more information. If you still cannot turn on the DME32, contact your Yamaha dealer. Make sure that the DME32 is turned on, DME Manager is up and running, and the connecting cable is connected properly. If you are using a 9-pin serial connection, make that the PC Control switch setting on the rear of the DME32 conforms to the type of serial port on your PC: RS232C or RS422. Make sure that the serial port on your PC is working correctly. Open the System control panel and click the Device Manager tab. See your Windows documentation for further information. If you are using a 9-pin serial connection and the message "COM port open error 5" appears, open the "setup.ini" file in the DME folder with a text editor and make sure that the COM setting is correct. If you are using COM port 2, for example, the setting should be "COM2". If that doesn't help, check if another device is already using the COM port and disable it. If you are using a USB connection, make sure that the USB port on your PC is working correctly. Open the System control panel and click the Device Manager tab. See your Windows documentation for further information. Only configuration memories that contain data can be selected for recalling. See "Recalling Configurations" on page 198. The SCENE No. indicator is flashing. This is normal and indicates that a scene memory other than the one last recalled or stored is selected. See page 199 and page 200. The LOCK indicator is not lit. The 48kHz and 44.1kHz indicators don't light up. This means that the DME32 is not wordclock locked to the selected wordclock source. Select another wordclock source. See "Selecting the Wordclock Source" on page 229. This is normal when an external wordclock source other than 48 kHz or 44.1 kHz is used. Cannot input or output audio. Noise occurs from the analog outputs when the wordclock source is changed on the wordclock master device. Check the I/O cards are installed properly and secured using the fixing screws. See "Installing I/O Cards" on page 255. See also "Checking the I/O Slots" on page 210. This is normal, although it's more likely to occur if an MY8-AT I/O card is installed. To eliminate the risk of speaker damage, turn down your power amps, or turn off the DME32 beforehand. A scene or configuration is being recalled unknowingly. Is the scene or configuration assigned to a MIDI Program Change and being recalled by external MIDI messages? See "Assigning Scenes & Configurations to Program Changes" on page 244. Is the scene or configuration assigned to a GPI input and responding to an external trigger? See "Assigning GPI Inputs" on page 214. DME32-Owner's Manual
