3.1 Opening The PULSAR
•
Unplug the power cord to turn off the P
ULSAR.
•
Unscrew the nine screws (Torx 10) holding the top cover.
•
Pull the top cover backwards and remove it.
•
Loosen the nine screws (Torx 10) holding the bottom cover.
•

3.2 Installing The Composite IF Aux Input Board
Observe Precaution for Handling Electrostatic Sensitive Devices.
Electrostatic Discharge (ESD) can damage the electronic components.
Therefore it is required to work in a static-save work station.
•
Install the optional board. See the internal layout for the correct location.
•
Fix the board with the 4 screws on the chassis profiles.
•

On the label you can find “/ XX”. This number indicates the software version.
Observe Precautions for Handling Electrostatic Sensitive Devices.
Electrostatic discharge (ESD) can damage the electronic components.
Therefore it is required to work in a static-safe work station.
For the location of the IC’s, use the Internal layout diagram.
•
Replace EPROM U65 with the one included in the kitbox. (only neccessary when the index of the
EPROM in the kitbox is higher than the one that is installed).
•
Replace GAL U69 with the one include in the kitbox. (only necessary when a GAL is included in
the kitbox and the index of the GAL in the kitbox is higher than the one that is installed).
