150 • SMP Gateway User Manual
A cable to convey screen-touching information.
When a touch screen is used with a computer, the screen also acts as a mouse when its user
touches it. The touch information is transmitted using either a USB or serial cable.
Note: If you have trouble connecting these cables to the SMP Gateway, refer to the
SMP 16 Installation Guide.
The use of a USB cable is recommended, as the SMP Gateway will detect it automatically: no
configuration is required. Just connect the USB cable to the screen and to one of the USB port of
the SMP Gateway.
If you must use a serial cable, follow these steps:
Connect the serial cable to the screen and to one of the serial port of the SMP Gateway. You
can use any port you like, except the Console port located on the front panel of the
SMP Gateway.
Start SMP Manager.
Select your SMP Gateway from the list.
From the Tools menu, click SMP Config.
Follow the procedure described in the “Configuring the Serial Port Interfaces” section, page
34, to specify the appropriate interface
(ELO Touchscreen) for the selected serial port.
