WARNING: Except the RS232 connector, all the circuits are directly biased to the negative

DC bus of the power stage, and J7 JTAG, J6 D/A output and J8 digital I/O connectors are not

isolated from the power ground. If an FS2 debugger or oscilloscope is needed for debugging

or measurement, ensure it is isolated from the power ground. Otherwise, severe damage will

occur to the PCB and /or the equipment.

2.1

PCB

The PCB has two electrical layers and its size is 6.5 x 8.0 inches.

2.2

Isolation Boundary

Note that there are two different grounds on this system. The RS232 connector is isolated by opto couplers so that

users can connect a computer without isolating it. However, users should keep in mind that most parts of the hardware
