2Installation
2.1 DigaStudio
1. Make sure that the power switch on the front of the DigaStudio Box is in the Off position
2. Plug the supplied power cable into the rear of the DigaStudio Box and then connect to a correctly
grounded power socket.
Note: The supply voltage can be in the range 100 ~ 240 Volt / 50 ~ 60 Hz.
3. Use the separately packaged cable to connect the DigaStudio Box with the DigaStudio Desk. Attach
the cable to the socket marked DESK on the DigaStudio Box and the socket marked MIXER on the
DigaStudio Desk.
4. Attach the required audio sources or sinks to the respective inputs. Analog symmetrical
sources/sinks are connected to the paired XLR sockets, analog asymmetrical sources/sinks (LINE
1, LINE 2, and Σ
ΣΣ
ΣOUT) via the respective cinch connectors.
A special 15-pol sub-D socket is available for direct analog connection of an PCX card (PCX). The
necessary audio cable is available as an optional extra (make sure that the cable is connected the
right way around as indicated by the cable markings).
There are also special 15-pol sub-D sockets for telephone hybrids, ISDN codec, and for the insert
path, whose connections are separately labeled.
For digital sources (DigaStudio Pro only) 2 AES/EBU inputs/outputs in XLR format are available.
A 6.3 mm stereo headphone connector is available on both the DigaStudio Box and the DigaStudio
Desk.
2.2 RS-422 adapter
The DigaStudio Box is connected to a PC via a RS-422 interface. Use the supplied connection kit in
accordance with the following instructions and note the safety information:
The following work should only be carried out by qualified personnel!
No liability will be accepted for damage caused by failure to follow the
following instructions correctly!
Before opening the PC case disconnect the power cable! Do not allow
any metal objects to fall into the PC!

DigaStudio Installation Notes Page 5 of 15
Before you come into contact with any electronic components make
sure that you are grounded and have discharged any static electricity!
1. Turn the PC off and open the case so that you have access to the rear slot-covers.
2. Select any free slot and remove its slot-cover. (Note: no ISA slot will be required).
3. Mount the slot-adapter in the space left by the slot-cover.
4. Attach an internal power cable to the adapter. Use the supplied Y-cable if no spare power cables
are available.
5. Make sure that there are no loose parts (screws, washers, etc) inside the PC and close the cover.
6. Connect the slot-adapter to a free RS-232 interface (COM port). Use either the 25 pol sub-D con-
nector or the long (2m) cable with the 9 pol sub-D connector depending on how the RS-232 inter-
faces are configured. Use the lower connector on the slot-adapter.
7. Now use the long (5m) connection cable to attach the slot-adapter with the DigaStudio Box. On the
slot-adapter use the upper connection, on the DigaStudio Box use the connection labelled PC.
2.3 PC software
The necessary software is included on diskette or will be sent via email1. The software is comprised of
the two files DSINTERFACE.EXE and DIGASTUDIO.EXE.
Proceed as follows to install the software:
1. Copy the two files into any directory on your computer. If the DigAS system is already installed on
your system then copy the two files into the DigAS system root.
2. First start the interface driver DSINTERFACE.EXE. In the system tray this program’s icon
should be visible.
3. Click with the right mouse button on this icon and from the context menu select
the option SHOW. This brings up a larger window with the name DigaStudio In-
terface Manager.
1In the future the latest updates can be downloaded from our mailbox. Information concerning updates is
available in our ISDN mailbox and on our internet homepage http://www/david-gmbh.de.

4. Click on the COM port button. A
window for RS-232 properties ap-
pears. Enter the paramters as
shown here. Make sure that you
choose the correct COM port, that
is, the one on the PC to which the
interface cable is connected. As a
rule this will be either COM1 or
COM2. When you have finished
entering all the necessary parame-
ters click on the OK button.
5. If the correct COM port has been selected then immediately after clicking on the OK button you
should receive the message „Serial thread started!„ in the output area of the DigaStudio Interface
Manager. If this is not the case then either the false COM port was selected or a resource conflict
exists (another application is using the COM port). If necessary correct the situation by repeating
step 4.
6. Close the window by clicking on the HIDE button. The icon should still be visible in the
system tray.
7. If required you should put a shortcut to the DigaStudio Interface Manager in the Windows
Autostart folder so that the program is started automatically when the PC is started. Follow the
instructions in the Windows manual if you do not know how to do this.
8. The DigaStudio Interface Manager can also be shut down via the CLOSE button in the context
menu (see step 3) should, for example, the serial interface be required by another program.
The PC software is now installed and ready for operation. Also, if you require, you can put a shortcut to
the DigaStudio Manager (program file DIGASTUDIO.EXE) on your desktop. This makes starting the
DigaStudio Manager more convenient.
