| Please note that display customisation and the changes to character sets described on
this page are only available to you before you make your order. These are not changes that can be made by the
user after a unit has been purchased. |
| We are often asked about customisation of our products. We always try to accomodate the requests that we can, however
what we can do is limited. We generally only do simple modifications to the software running on our existing products.
For example selecting a subset of the gps data for display. If you come to us with a well defined specification
then we will always look at it and see if we can help. However if you don't take the time to understand you own
needs and develop a specification then we cannot provide you with a solution. See the example sent to us by a customer
below. He presented exactly what he wanted in a very clear and concise way. As well as the display he also wanted
a brake switch input connection. Having understood the layout and connections of our unit he was able to define
his own circuitry to interface to the electronics of the vehicle. This allowed us to define the brake switching
input as a normally open TTL level connection to work with his interface. |
|
|
| When we had looked at the specification we were able to explain the limitation of the unit with regard to the number
of characters per line. This meant we had to rearrange the customer's display layout slightly. After mocking up
the changes we were able to agree the final layout as shown below. |
|
|
| This layout and the brake switch input were then implemented and tested. The test video shown below was then sent
to the customer for his final approval before the custom unit was dispatched. |

| Smaller characters and different character sets |
We can create displays that have characters smaller than the standard character set. However the hardware does
have limitations which need to be understood. The characters are generated on a fixed grid of cells, each 12 by
18. This means that while the character size can be reduced within each cell, the spacing between characters is
fixed. The size of the area highlighted when the character background is selected is also fixed. The fixed size
character cells limit the display to the full width of the screen. Please take into account the likely resolution
of your display and playback devices as well as the compression used. Small characters are likely to be illegible
on a small screen.
Character sets like Hebrew or Cyrillic can be added to the characters available in the ID String position. |
