2 I am currently powering the 7i76 5v logic power from 5i25 is that going to be a problem if connecting encoders?
I will attach a screen shot of the encoder stuff in the manual.
How many encoders and what current do they consume? from the manual...
EXTERNAL 5V POWER
The 7I77s 5V power for the analog, RS-422, and encoder section has an
approximately 650 mA current drain. Installed encoders, RS-422 devices, and load on the
analog outputs can increase this to up to 2A. This is in excess of the host FPGA cards
current supply capacity. So when longer cables or high power drain encoders are used, or
PC 5V is toward the low side, external 5V power should be supplied to the 7I77s TB1
connector. Both the FPGA card and the 7I77 have power jumpers that must be correctly
set to match the 5V power source (see hardware configuration section)
