Programming information for the D/A controller is provided in “Software 

Summary” on page 17.

The analog output channels are terminated at J1 and J3. The pin 

definitions are shown in the illustration below.

Layout and Pin Reference

Connector

• PCB connector: TEKA SRC205C425M126-0 (J1), TEKA SVC205B3580135-

0 (J3)

• Mating connector: ITW-PANCON 050-010-455A

7.3.3 J8, J9 Digital I/O Headers

The PCM-MIO-A-1 and PCM-MIO-A-AD-1 use the Lattice MachXO2 FPGA 

with WINSYSTEMS WS16C48 ASIC compatible programmed logic. The 48 

lines are each individually programmable as input or output and the first 

24 lines are capable of fully latched event sensing with edge polarity being 

software programmable.

The 48 lines of parallel I/O are terminated through two 50-pin connectors 

at 

J8

 and 

J9

. The 

J9

 connector handles I/O ports 0-2 while 

J8

 handles ports 

3-5. The pin definitions for 

J8

 and 

J9

 are shown below.
