HAWK-800 Kit Mounting Hardware for the PS-800

HAWK-800 kits that are for the PS-800 (original Poly-800) that are shipped out after July 2018 are provided with four
mounting posts, screws and washers. These are for use in mounting the HAWK board into the Poly-800. We have not yet
provided detailed instructions for their best installation. Contact

Troubleshooting the HAWK-800 Kit Installation

So you have installed the HAWK-800 and plugged everything in and tried to power on but all you got was random
characters on the display or perhaps a completely blank display with no sound, not any sign of life at all. Well, you need to
go through the following steps one at a time.
Power Supply Check
1. Check that the power supply adapter is rated 9V DC and the current rating is 500mA or higher.
2. Check that the +5V supply on the main board is precisely +5 volts. Be extremely careful when checking the +5V
rail. Do NOT short out any component pins. You can check the voltage easiest on the HAWK board. See the picture
below. Set your multimeter to DC 10V measurement setting and then check for exactly 5 volts measured across
the capacitor in the top right hand position. You will need to open your synth up, carefully lay to the two halves
down so that all cables remain connected. Then power on the synth and carefully measure the +5V rail. NOTE: the
picture shows the AtomaHawk connector installed on the HAWK board. Most likely, your HAWK should NOT have
that installed as yet.
Check Component Location and Orientation
Check that you installed all of the components into the HAWK board in their correct locations and correctly oriented.
Check Ribbon Cables
Check that there are broken or bent over pins on the two ribbon cable assemblies. Check both ends of both cables. Then
check that you install them correctly. Sometimes people misalign the cables by one or two rows. Make sure they are
installed as shown in the pictures in the instructions.
