MVME162 to address I/O locations on the IndustryPack module
designated by the four ''select'' lines.
Ack*
Data Acknowledge. Asserted by an IndustryPack module to
terminate each data transfer.
+5STBY
+5 Vdc Standby. Second of two +5V pins. Available for
standby functions on the IndustryPack, such as non-volatile
memory, real-time clocks, etc.
GND
Ground. Fourth of four ground pins. Serves as zero-volt
reference for logic signals, and as return path for the power
supplies furnishing operating voltages to the IndustryPack.
Connectors J3 and J4 provide the I/O for the IndustryPack modules. On
the controller's PCB, they are connected in parallel with J7 and J5.
Connector J3 is wired in parallel with J7 and connector J4 is wired in
parallel with J5. For example:
Pin 1 is connected to pin 1
Pin 25 is connected to pin 25
Pin 50 is connected to pin 50
A 50-conductor ribbon cable is then attached to connector J3 and J4 to
provide the I/O.
