-> Hardware IDs shows PID=0x4E7).
• Right-click on Elo's <USB Input Device>, and follow these steps:
− Update Driver Software...
− Browse my computer for driver software
− Let me pick from a list of device drivers on my computer
− Click the "Have Disk..." button
− Browse to the location of Elo package and choose EloMTUsb.inf
− Choose the correct entry (For Example, "Elo Touch Solutions Touchscreen 0x22
2515U IT Plus")
− Click "Next" to complete the installation.
• Identify Elo device under "HID-compliant consumer control device", and repeat steps a
through g above, but at step f, choose "Elo Touch Solutions Touch Screen - USB HID MT
Collection”.
6.1.2 Uninstallation
To uninstall Elo drivers from the Device Manager, right-click on "Elo Touch Solutions Touch
Screen - USB HID MT Collection", and select Uninstall. Repeat process for "Elo Touch Solutions
Touch Screen 0x22 2515U IT Plus".
You may need to manually refresh the device list (at root level, choose "Scan for hardware
changes") to get the device status updated to system defaults. It may take a while (10 - 30 sec)
for the "USB Input Device" and "HID-compliant consumer control device" to get restored.
6.2 Sending Smartset Commands
Users can specify Smartset commands in EloOptions.ini to be sent to the controller whenever Elo's
device driver is loaded. This feature applies to Elo touch screens using USB or Serial (RS-232)
interface with Elo's device driver installed.
6.2.1 Format of the Smartset Command in EloOptions.ini:
Specify Smartset Commands under section [Smartset Commands]. Smartset commands listed
under this section will be sent each time Elo's device driver is loaded. This happens when the
system reboots; or for USB interface, when the USB cable is re-plugged in.
Each Smartset Command takes one line. Below is an example line of a Smartset command (n1
to n8 are decimal numbers):
my_ss_command = n1 n2 n3 n4 n5 n6 n7 n8
In the example above, "my_ss_command" is the string you name this line of Smartset
commands.
The contents of each Smartset Command must be in 8 positive DECIMAL numbers (<= 255)
