Touchscreen Interface Options
The touchscreen
interface controls the transfer of touch data from the computer to the
touchscreen and vice versa, and is in addition to the standard monitor
video and power cables.
- Serial
Interface: A general-purpose interface, where one cable connects
the touchscreen to an available COM port. All modern Elo serial
monitors have
internal controllers (inside the monitor), with a female DB9 (9 pin D-shaped) touch
output connector. The connection to the male-pinned COM port is made
by a standard straight-through male-to-female DB9 cable.
- USB Interface:
Short for Universal Serial Bus, an interface that supports
Plug-and-Play installation and hot plugging. One cable connects the
touchscreen to an available USB port.
- Dual Serial/USB (Combo) Interface: Provides both serial and USB
interfaces-one or the other should be used, not both.
- PC-Bus
Interface (Obsolete): An expansion card that is installed inside the computer
in an ISA bus slot. Elo
monitors intended for use with PC-Bus controllers have a male DB9 (9
pin D-shaped) touch output connector. The connection to the
female-pinned bus controller card is made by a standard male-to-female
DB9 cable.
