E271-2200 AND E271-2210 SERIAL CONTROLLERS
Serial Controller Installation
This section assumes you are integrating the E271-2200 or E271-2210 serial
controller board into your system as a component. The controller is also available
in kits and enclosures with cabling and a power supply. See the AccuTouch
Product Manual for various integration options.
The following information gives you the controllers' mounting dimensions, the
touchscreen connections, the power connections and requirements, and the output
connections. It is your responsibility to determine how best to mount the controller
and output connector in the display or separate enclosure, and provide a power
supply.
A Generic Internal AccuTouch Touchscreen Controller Mounting Kit (P/N
UK0020) is available from Elo for mounting the E271-2200 or E271-2210
controller inside a display. It includes wiring harnesses and cables, mounting
hardware, and a DB9 female bulkhead connector. A power supply is available
separately (P/N 400000).
Mounting the Controller and Connecting Chassis Ground
The mounting dimensions for the E271-2200 and E271-2210 controllers shown in
Figure 2-2 and Figure 2-3, pages 10 and 12 respectively. Remember that the cable
headers will increase the space required.
The mounting holes fit common 0.156 inch plastic snap-in standoffs. A chassis
ground connection is required through one of the plated mounting holes (PTH) to
provide a return path for the on-board transient protection. Conductive mounting
hardware can provide a chassis ground connection for the controller.
Serial Controller Connections
Power Connections
The E271-2200 and E271-2210 controllers operate on a single voltage, positive
with respect to ground. See page 121 for power requirements.
Connect a power cable harness to P4 on the controller, a 1x2 header with pins on
0.100" centers. The recommended mating plug is a Molex polarized, locking crimp
terminal housing #22-01-3027. The power connection is labeled to designate the
positive (+) and ground (-) pins. Connect a power supply (such as Elo P/N
400000) to the harness and then to AC.
