3.10 VCC Pin
There is one pin named VCC+5V on Pin5 of CN1. This voltage source is from
computer directly. Please don't use this voltage source on any devices which
are connected to PCI-8136M's isolation I/Os. If not, the grounds will be
connected both at the isolative sides and the noise will be introduced from
this loop. So the isolati on will be meaningless. The VCC's ground is the same
with Analog's. Please be careful to deal with the noise problems.
