| 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 |
| At the time you make your order we can provide one of two alternate character sets to the default standard character
set. The character set cannot be changed by the user once units are delivered. The standard character set is
suitable for a wide range of applications including those where small screens are used or viewed at a distance.
The smaller alternate character sets can be more suitable for use with LCD panel displays. 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 fixed size character cells limit the display to the full width of the screen, as shown below. |

Alternate smaller character set 2

|
| The size of the area highlighted when the character background is selected is also fixed, as shown below. Please
take into account the likely resolution of your display and playback devices as well as the compression used. Small
characters can be illegible on a small screen or when viewed at a distance. |

provided. |
