2 Chapter 1 - Introduction

• High speed -- can transmit over 200 coordinates per second.

• Bi-directional communication with acknowledgements.

• Sophisticated command set and communication protocol consistent among the

SmartSet controllers.

• On-board calibration and scaling of touch coordinates, untouch detection

(lifting of the finger), and programmable coordinate output rate.

• Configuration options can be stored in nonvolatile RAM (NVRAM) or set with

jumpers.

• Advanced four-layer surface-mount design for small size and low profile.

CMOS circuitry insures low power consumption. Custom ASICs enhance

reliability. Full power and ground planes enhance noise immunity and radio

frequency interference (RFI) immunity. Analog input filters also eliminate

electrical noise from the display. Rugged bipolar transistors are used to drive

the touchscreen and the output stage is protected by Raychem PolySwitches.

Linearity is preserved with a ratiometric measurement subsystem.

• Electrically and 100% functionally tested with a microprocessor-controlled

automated test set.

• On-board diagnostics and LED status indicators.

E271-2200 Serial Controller

• Uses the popular EIA RS-232C serial interface for connection to a wide range

of host computers.

• Communication parameters may be configured for a variety of serial

characteristics and baud rates (up to 38K baud).

• Hardware and software handshaking supported, along with packet checksums

for reliable communications.

• Has a 3.3" x 4.325" outline and low profile.

• Low power requirements: 65ma @ +5Vdc ±10% standby, 160ma average

when touched, 240ma peak. Special low-power mode for battery operation.

• AccuTouch E271-140, DuraTouch E261-280, and IntelliTouch® E281A-4002

controller emulation.

E271-2210 Serial Controller

Same as the E271-2200 with the following exceptions:

1 2 ... 7 8 9 10 11 12 13 14 15 16 17 ... 138 139
