Wiring SmartTouch into an existing SMARTCASTER
If adding the SmartTouch to an already existing SMARTCASTER, some additional steps are needed.
First, a card, (PCL-720 Digital I/O Card), needs to be installed into an empty card slot in the computer.
This card sends and receives the one’s and zero’s used to communicate with SmartTouch. To insert the
card, remove the cover from the SMARTCASTER, and locate an empty card slot. Remove the filler panel
for the slot, and insert the card. (This may require some ‘rocking’ of the card from front to back to allow
the card to drop into place.) Please make sure the dip switch settings are set as follows before continuing:

After inserting the card, the Wiring Harness needs to be connected. The Wiring Harness consists of two
20 pin connectors on one end, and the other end is attached to a 25- pin D-sub connector. The first 20 pin
connector, labeled “Con 1”, should be connected to connector three as shown on the following page. The
second connector, labeled “Con 2”, should be connected to connector four. Finally, the 25- pin connector
should be brought out to one of the spare punch-panels located on the back of the SMARTCASTER,
between the power supply and the computer cards.
