3 Mounting the kit into a case
The OSCAR kit can be mounted into any rack or case. A metal case is recommended.
Please be aware of your national security regulations, especially if you plan to use a power
supply connected to the mains.
For the mounting, please take care of the following recommendations:
- Audio ground and power supply ground should not be connected anywhere. An isolated
mounting of the line out and head phone connectors is recommended
- All AF lines should be kept as short as possible. A shielded cable shoud be used.
- All flat cables should be kept as short as possible, 30 - 40 cm is the maximum length
which is recommended.
- The case should be as HF tight as possible, a good metal rack is recommended.
- If you plan to use an additional hard disk, please look up the recommendations in the
OSCAR user manual.
- The trimmer for the contrast adjustment on the front PCB is accessible thhrough a whole
in the PCB. Please make sure that you cann access this trimmer after mounting the kit
into the case (or regulate contrast before mounting OSCAR into the case)
- The axis of the rotary encoder is connected to one of it’s output signals. The knob to be
used should either be isolated or should be mounted isolated from the axis to prevent
electrostatic damage.
4 Getting OSCAR started
Before powering up, please check all connections as described in section 2. Especially the
correct connection of the power supply is crucial to prevent damage. Please make sure that
the CD-ROM is connected to the power supply, too.
Main PCB and front PCB have been factory checked on proper function, so OSCAR should
start up without problems if you have connected everything right.
Before powering up, turn the knob for LCD to the left. After powering up, the initialisation
message should appear on the LCD display and the display should be illuminated. If you
cannot see the initialisation message, try to adjust the contrast trimmer over ist full range.
