Cables and KVM Extenders: Moving signals from the control room to the industrial touch screen

At Hope Industrial Systems, we like to say “we sell industrial monitors and touch screens, and things to help you buy our monitors and touch screens.” This means we carry a variety of mounts, keyboards, screen protectors, cabling options and other accessories so that a customer can build a full custom workstation based on our displays and touch screens.

Noticeably absent from this list is computers. While most of our customers connect our screens to some sort of PC, we at Hope Industrial do not sell PC’s because we believe that Tier 1 computer vendors, like Dell and HP, are better at making and supporting basic computers than we or any other industrial equipment manufacturers could ever be. There are a variety of reasons for this that we will save for another post.

The model that many of our customers follow is to put a desktop or server-class PC in a clean room out of harm’s way, exposing only our rugged displays and workstations to the rigors of the factory floor. To get the touch screen and video signals back to this clean room, we offer a variety of solutions: Continue Reading…

Automation Technology South Expo Recap

We are wrapping up our trip to Orlando, FL for the 2011 Automation Technology South Expo (ATX South).  The weather has been great, as you would expect central Florida to be in March.

Product Tip: Calibrating “Below the Touch Point”

When doing an initial touch screen alignment, the Elo drivers used in all of our industrial touch screens display the standard “touch the targets” dialog:  the user is shown a series of onscreen targets and asked to click on them.

Why do we use Resistive Touch Screens?

At Hope Industrial we have always used resistive sensors in our industrial touch screens. Specifically, we use 5-wire AccuTouch Resistive Touchscreens from Elo Touchsystems.

Touch Screen Sensor

AccuTouch Resistive Touch Screen Sensor

Resistive touch screens are made of at least two layers of flexible sheet (polycarbonate, in our case) laid atop a glass substrate. The sheets are coated with a resistive substance and are kept separated by tiny dots. When the touch screen is pressed, the flexible layers are pushed together, generating a change in resistance on both vertical and horizontal axis. This change in resistance is measured by sensors on the edges of the screen and the degree of change is measured as a touch point. Of course there are a variety of different touch technologies out there: Surface Acoustic Wave (SAW), Capacitive, Infrared, etc.

Interesting stuff, but the point of this post is not to compare and contrast these technologies (Wikipedia does a great job of that already), but to explain why we chose 5-wire resistive, and why we use Elo products specifically. Continue Reading…

Sulfur Protection

Many industrial environments have invisible airborne substances that can damage electronic equipment.  Dust and moisture in the air are common enemies of electronic circuits.  There are other less common substances that are found in specific industrial environments that can be even more damaging.

Sulfur is one of those substances.  Airborne sulfur uses moisture in the air and is corrosive to the copper and silver commonly found in the conductive traces on circuit boards, in LCD circuits and resistive touch screens.  All of these components are found in the construction of an industrial lcd monitor.

Configuring a Fully-Enclosed Universal Mount Monitor – Part II

In this post we will continue breaking down the main components for completing a Universal Mount Monitor configuration. In Part I, we detailed the various cable exit cover plate options for our fully-enclosed Universal Mount Monitors. The next step to completing your configuration is deciding how you want to mount the monitor.

All of our Universal Mount Monitors have side yoke mount holes, as well as VESA mounting holes on the rear cover. You can mount the monitors virtually anywhere – on a pedestal anchored to the floor, attached to a wall, column or post, or even hung from the ceiling! Continue Reading…

Linux drivers for Industrial Touchscreens

Linux Tux in hard-hatFor today’s post we will provide a quick overview of how Elo handles drivers for Linux systems.  We use Elo Accutouch resistive touchscreen sensors and controllers in almost all of our touch-enabled products, and Elo offers very robust support for the Linux platform.

Elo offers both pre-built installation packages for common Linux distributions, and source code for other distributions (or for anyone who would like to customize or modify the drivers).  All of this is available on the main Elo touchscreen driver page.  Once you accept their standard EULA, you are presented with a range of ready-to-run Linux drivers.
