Removing the MIDI PCB (DL1000)
Before beginning any service work, remove all power to the unit and disconnect any signal cables where
necessary. Adopt static electricity working procedures when carrying out service work. Ensure
adequate lighting and use the correct tools. Access to the MIDI circuit board can only be achieved once
the console has been opened (see ‘Opening up the DL1000 console’).
1)
Remove the 4 plastic jack sockets from the rear of the console (see fig.5)
2)
Remove the 2 RS232 nuts (see fig.5)
3)
Remove the connecting earth wire to the MIDI circuit board from the earth post (see fig.6)
4)
The MIDI circuit board assembly can now be removed from the console.
When all service work is complete, remove all debris such as solder, component legs and wire clippings
from inside the unit and check your work carefully before re-assembly. To refit the MIDI circuit board
assembly, follow the above procedure in reverse order. Make sure the Earth wire is connected to the
earth post. Test for correct operation.
