Elo offers PC-Bus and serial (RS-232) controllers for AccuTouch touchscreens.
The serial controller may be purchased in a Tabletop enclosure (see Chapter 3)
or as components. This section includes a procedure for installing a CTR-
221000-AT-SER serial controller inside the monitor.

Regardless of the configuration of touchscreen and controller, you are
responsible for any recertification for agency approvals (FCC, UL/CSA, TÜV,
CE, etc.) that may be necessary for your application.
