• Electrical
• Environmental
• Physical Characteristics
• LED Diagnostic Characteristics
• Agency Approvals
• Drawings
• Options

Electrical

Supply Voltage and Current

• +5 VDC, nominal (+4.75 to +5.25 VDC)
• 120 mA, typical at +5 VDC. Average power dissipation is 0.6 W, typical.
• Supply must be capable of sourcing 400 mA, minimum.
• Total noise and ripple requirement must be less than 100 mV (p-p) for all frequencies

Interface

• EIA 232E (Serial RS-232), DCE configuration. 8 Data Bits, 1 Stop Bit, No Parity, Full Duplex.
• Hardware handshaking: RTS/CTS.
• DSR is pulled HIGH (>+3V) by the 4000S when connected and powered. DTR can be asserted by the host to interrupt the flow of data from the controller. 
  Note that if the application does not monitor CTS, then an interval of approximately 5 seconds should be inserted between the issuance of a reset command and any other command.

Baud Rate

• 9600 (default)

Operating Modes

• Full Infrared SmartSet protocol

Touch Resolution

• 4096x4096

Conversion Time

• Approximately 25 ms per coordinate set

Reliability

• Reliability predictions were performed in accordance with MIL-HDBK-217F Notice 2 and Bellcore TR-NWT-000332 Issue 4. The environment for both predictions was Ground Benign at 35 degrees C. The calculated reliability hours are:
  • MIL-HDBK-217F: 629,693
  • Bellcore: 763,114

Environmental

Temperature

• Operating: -20°C to 70°C
• Storage: -40°C to 85°C

Humidity

• Operating: 0% to 95% RH, noncondensing
• Storage: 0% to 95% RH, noncondensing

Operating Altitude

• 10,000 feet

Shock and Vibration

• Three axis sine wave, 50 Hz to 2kHz, 1 G, 2 minutes/Octave with dwell on resonances

ESD

• Test pending

Flammability

• The printed circuit board substrate is rated 94V0. All plastic components, such as headers and connectors, are also rated 94V0.

Physical Characteristics

Construction

• Four-layer surface-mount design with internal ground plane for EMI suppression

Dimensions

• Total width: 2.30 inches (58.42 mm), including connectors
• Total length: 3.30 inches (83.82 mm)
• Total height: 0.40 inches (10.16 mm)
• All mounting holes are plated through for chassis ground connection. 

Connectors and Pin Definitions

The connector configuration permits the controller to be placed in-line between the touchscreen and serial I/O attachments.

Serial connector, P2, and signal descriptions

The serial I/O connector, P2, is a dual row by five position header with 0.025 inch pins on 0.100 centers. The header is compatible with insulation displacement cable (IDC) connectors such as Berg series 71600, series 71602, series 66900, and series 66902, Molex style 40312, Amp series 746285 and series 746288 receptacles. The header is also compatible with crimp termination, discrete wire receptacles and housings including Berg Mini-Latch housings and Mini-PV receptacles, Molex series 70450 connectors, and the Amp AMPMODU Mod. IV connector family. Pin numbering schemes for discrete wire connectors differ between manufacturers. Refer to Figure 1 for pin number locations. When the mating IDC receptacle is cabled to an IDC DB-9 connector, the interface assumes a DCE configuration as described in ANSI/EIA/TIA 232-E.

Power connector, P4 

The power connector, P4, is a dual row by five-position header with 0.025-inch pins on 0.100 centers. The header is compatible with insulation displacement cable (IDC) connectors such as Berg series 71600, series 71602, series 66900, and series 66902, Molex style 40312, Amp series 746285 and series 746288 receptacles. The header is also compatible with crimp termination, discrete wire receptacles and housings including Berg Mini-Latch housings and Mini-PV receptacles, Molex series 70450 connectors, and the Amp AMPMODU Mod. IV connector family. Pin numbering schemes for discrete wire connectors differ between manufacturers.

Refer to Figure 2 for pin number locations. Signal connections are shown in Table 3.
