Touchscreen Cabling System for Internal Serial Controller

Follow these steps to install an IntelliTouch serial controller:

1Evaluate the monitor for proper positioning of the cont rolle r. Make su re th ere

is sufficient space for cable headers.

2Evaluate the back case of the monitor to determine the best position for the

DB9 female connector. A hole for this connector may be furnished in a

variety of ways: a) mounting the connector to a chassis member that is

exposed to the display exterior, b) mounting the connector to a chassis

member with a hole in the exte rior of the case to provide acces s to the

connector, and c) mounting the connector to the case.

3Mount and ground the controller card following one of the two methods:

•Mount the controller to the metal chassis using metal screws and spacers.

It can be grounded through one of the mounting holes by using one of the

No. 6 sheet metal screws and spacers provided in the kit (See “Elo Part

Numbers” on pageC -79 for installation kit part number). On the 2500S,

all mounting holes are plated.
