Product Information
The NXP-TPI/4 (FIG. 1) is a touch panel interface that supports AMX’s 4th generation graphics (G4)
consisting of both rich colors and support for high-contrast images. This G4 interface device is capable
of mixing Video/RGB inputs and then combining those inputs with graphics, which can then be
displayed on a variety of monitors. The TPI/4 can support upgradeable memory modules of up to 256
MB and Compact Flash cards of up to 1 GB for more graphics-intensive TPD4 files.
The rear HD-15 VGA connector can output a maximum resolution of 1280 x 1024 pixels. The
TPI/4 allows for up to four resizeable media windows; each displaying 24-bit real-time
RGB/Video/S-Video. AMX G4 graphics are available using 32-bit touch panel images (16 million
colors). An 8-bit alpha-channel feature is used for alpha blending and opacity.
The four slots on the rear of the panel interface can accept VGA and Composite/S-Video input signals.
The NXP-TPI/4 (TPI/4) can use any combination of up to four TP4 input cards.
FIG. 2 shows the two available TP4 cards:
TP4-RGB - HD-15 RGB input and USB host port for mouse/keyboard control.
TP4-VID - Composite and S-Video input.
The TPI/4 receives control and touch point information from a variety of pointing devices such as a
touch screen, mouse, and keyboard. The unit connects to a control system through either an ICSNet
(direct connect) or Ethernet port (via a network or over the Internet). The TPI/4 acts as a video switcher
and allows users to incorporate large-scale touch-screen technology from a variety of manufactures into
an AMX NetLinx controlled system.
