    Option 2 provides an 8K x 16 dual-ported RAM for USB, Ethernet or PC/104 ports on board of the ACC- 2P communications board. If using for USB or Ethernet communications, ACC-2P-Opt-1A or ACC-2P- Opt-1B must be ordered. If used for PC/104-bus communications, PMAC2A-PC/104-Opt-2A must be ordered. The key component installed with this option is U17.

    PMAC2A-PC/104 ACC-2P HARDWARE SETUP On the ACC-2P, you will see many jumpers (pairs of metal prongs), called E-points. Some have been shorted together; others have been left open. These jumpers customize the hardware features of the ACC- 2P for a given application and must be setup appropriately. The following is an overview of the several jumpers grouped in appropriate categories.

    PMAC2A-PC/104 setup, through the I-variables I9n2. However, for the following reasons, the same type of switches used for over-travel limits are recommended: • Normally closed switches are proven to have greater electrical noise rejection than normally open types. • Using the same type of switches for every input flag simplifies maintenance stock and replacements.
