This terminal block may be used as an alternative power supply connector if PMAC is not installed in a PCI-bus.
The +5V powers the digital electronics. The +12V and -12V (if jumpers E85, E87, and E88 are installed), power the
analog output stage (this defeats the optical isolation on PMAC).
To keep the optical isolation between the digital and analog circuits on PMAC, provide analog power (+/-12V to +/-
15V and AGND) through the JMACH connector, instead of the bus connector or this terminal block.
