Product overview

The Danfoss 2 x 24 serial display module is designed for the demanding operating conditions and

environments common to mobile machine applications.

The display module integrates an industry standard New Twisted Nematic (NTN) LCD alpha numeric

display glass with robust high impact plastic packaging and interface electronics allowing installation in

no cab and open cab machines.

Superior readability in all ambient light conditions is accomplished through the use of a transflective,

backlit type of display with dark characters on a green background. An adjustable viewing angle option

(controlled via software) allows machine operators to adjust display contrast to compensate for changing

light conditions and operator position. Character clarity is enhanced by a 5 x 7 dot matrix character.

2 x 24 display modules are designed to be used in conjunction with Danfoss microcontrollers via RS232

serial communication. Danfoss electronics embedded in the display module convert serial character

transmission to the parallel format required by the display.

Theory of operation

Danfoss 2 x 24 Display Modules are designed to operate in conjunction with Danfoss microcontrollers.

The generation of display messages is typically an integral part of the application program running in the

microcontroller. Character information is transmitted from the microcontroller to the display module via

RS232 standard signal levels and protocol operating at 9600 Baud.

Danfoss proprietary interface electronics embedded in the display module converts microcontroller serial

data to the parallel data format required by the LCD display driver. The Display Module is a receive only

device and does not return any information to the microcontroller.

Display readability is influenced by two parameters:

•

The operator’s spatial relationship to the display and the display viewing angle (also referred to as

viewing cone).

Spatial relationship can be described as either direct horizon view or 30 to 45 degrees above horizon.

See the following illustration.

•

Display viewing angle can be either fixed or variable. Fixed viewing angle displays have a factory set

voltage that cannot be adjusted after manufacture. Variable viewing angle (also referred to as

contrast) is controlled by varying the voltage applied to the capacitive fluid in the display glass which

changes the alignment of display particles.

Variable displays allow the user to adjust display glass contrast control voltage in a step-wise manner

through software control from the microcontroller. The display voltage control range is controlled over

100 steps. Variable displays are typically used in applications where there is no cab and variable lighting

conditions.

Displays with variable viewing angles will default to the most recent control voltage at power-up.

Machine wiring guidelines

•

Protect wires from mechanical abuse, run wires in flexible metal or plastic conduits.

•

Use 85˚ C (185˚ F) wire with abrasion resistant insulation and 105˚ C (221˚ F) wire should be

considered near hot surfaces.

•

Use a wire size that is appropriate for the module connector.

•

Separate high current wires such as solenoids, lights, alternators or fuel pumps from sensor and other

noise-sensitive input wires.

•

Run wires along the inside of, or close to, metal machine surfaces where possible, this simulates a

shield which will minimize the effects of EMI/RFI radiation.

•

Do not run wires near sharp metal corners, consider running wires through a grommet when

rounding a corner.

•

Do not run wires near hot machine members.

•

Provide strain relief for all wires.

•

Avoid running wires near moving or vibrating components.

•

Avoid long, unsupported wire spans.

•

Ground electronic modules to a dedicated conductor of sufficient size that is connected to the

battery (-).

•

Power the sensors and valve drive circuits by their dedicated wired power sources and ground

returns.

•

Twist sensor lines about one turn every 10 cm (4 in).

•

Use wire harness anchors that will allow wires to float with respect to the machine rather than rigid

anchors.

Warning

Unintended movement of the machine or mechanism may cause injury to the technician or bystanders.

The module will be powered up if battery voltage is applied to the module's output pin. To protect

against unintended movement, secure the machine.

Caution

Warranty will be voided if module is damaged.

Avoid significant current driven back through an output pin.
