Display Module PCU-6D

PCU-6D is a small, lightweight display module designed to present drivers with the information they require in a clearly-legible and simple format via alphanumeric LED displays and LED lamps.

Diagnostic monitoring of the unit is via a 1Mbps CAN interface, and control may be via CAN or a synchronous serial interface (clock, data, strobe and PWM brightness signals).

In Detail

Application

  • Data display

Display

    • A single digit, fitted centrally, indicating gear number.
    • Size: 14.22mm high by 8mm wide.
    • This is a seven-segment red display with a right-hand decimal point.
    • Two smaller four-character displays flanking the central digit.
    • Each digit is 10.16mm high by 6mm wide.
    • These are alphanumeric ‘starburst’ red LED displays with right-hand decimal points.
    • Two high-intensity red, two high-intensity yellow and two high-intensity blue LED indicators positioned at the extreme left and right of the unit.
    • A horizontal bar of 15 high-intensity LEDs at the top edge of the assembly. The five left-hand LEDs are high-intensity green, the five middle LEDs are high-intensity red, and the five right-hand LEDs are high-intensity blue
  • If the unit’s synchronous serial interface is used, the intensity of the warning and shift LEDs is controlled by a PWM brightness input signal, which can be pulse-width modulated at approximately 200Hz to adjust the intensity. Alternatively, if the CAN interface is used for control of the unit, the intensities of these LEDs and the alphanumeric displays may be independently set using CAN messaging.
  • When the synchronous serial interface is used, the PWM brightness input signal can be left unconnected, resulting in maximum brightness.
  • A grey acrylic circularly-polarised anti-glare front screen covers the alphanumberic and seven-segment LED displays. This enhances the contrast between light from the display and incident light due to polarised filters absorbing back-reflected light.
  • The LEDs on the front face of the unit are covered by a grey velvet polycarbonate label with clear windows.

Unit Inputs

  • One reset input (active low with internal pull-up; can be left unconnected if not required)
  • One CAN address selection analogue input (connect an external resistor to unit supply ground)

Communications

  • 1Mbps CAN interface (no internal termination)
  • A range of extended (29 bit) and standard (11 bit) CAN IDs are supported
  • Synchronous serial interface

Diagnostics

  • Internal board temperature
  • Supply voltage
  • Six warning LED drive voltages

Electrical

  • Supply voltage: 7.5V to 16V DC
  • Unit is protected against transients
    • Quiescent (all LEDs off): 70mA typ @ 13.8V
    • Operating (all LEDs on): 0.6A typ @ 13.8V
    • Operating input voltage range: 0V to 5V
    • Maximum protected input voltage range: ±16V
    • Input filter time constant: 1μs
    • Input termination: 4.7kΩ internal pull-up to 5V
    • Input low threshold: 1.0V min
    • Input high threshold: 3.5V max

Electro Magnetic Compatibility

  • Complies with the essential protection requirements of 2004/108/EEC
