SnapAmp - Connector Pinouts

 

SnapAmp contains three connectors labeled JP1, JP6, and JP7. 

 

JP6 - KMotion Communication & Logic Power

 

JP6 is a proprietary high-speed communication bus where command and status communication between the KMotion board and the SnapAmp Amplifier.   Up to two SnapAmps may be attached to a single KMotion Board.  The second of the two SnapAmps must have a configuration jumper installed into JP5.

 

This connection is required for proper operation of the SnapAmp and should be as short as possible.

 

16 pin ribbon cable connection between SnapAmp and KMotion.

 

Note: 4 - 40 x 1 3/8 inch standoffs are used between SnapAmp (top) and KMotion (bottom).

 

 

16 pin ribbon cable connection between Dual SnapAmps and KMotion

 

Notes:

4 - 40 x 1 3/8 inch standoffs are used between SnapAmp and KMotion

4 - 40 x 1 5/8 inch standoffs are used between SnapAmps

JP5 Jumper installed configures a SnapAmp as the 2nd SnapAmp.

 

 

 

 

When attaching SnapAmp to the KMotion first attach main ground plug as shown.

 

 

 

 

 

For Dual Snap Amp systems attach the 1:2 spade Y adapter before connecting the first SnapAmp

 

 

 

 

 

JP7 - I/O - General Purpose LVTTL - OPTO Isolated - Differential - Encoder Inputs

 

JP7 Is used for all Digital I/O.  Fourteen General Purpose LVTTL I/O, Eight Differential Encoder Inputs, and Eight Optically Isolated Inputs.

 

 

Optically isolated input circuit.  5-12V may be applied.  Current requirements at 5V is approximately 6ma and at 12V is approximately 20ma.
