One of the things which really attracted me to the Texecom panels was the ability to interface them directly with the computer – and other things (to be described in a future post). However, in order to do this you need to buy a fairly expensive cable from Texecom – the COM-USB:
These seem to retail for about £40, although there are some cheaper 3rd party versions on ebay for rather less, which seem to do exactly the same job:
However even this seems a bit steep for what looks a fairly simply USB cable, and the pins on the Premier Elite main board also appear fairly standard.
I then came across this extremely helpful post:
In which the author has discovered that the connector on the board is no more than a straightforward serial connection, with three pins – TXD, RXD and GND – connected. Using a USB-serial converter he was able to get everything working with the official ‘Wintex’ software which is a free download from Texecom.
I took a slightly different approach and bought from ebay a very small board which converts a mini-USB plug into serial with pins and solder points as outputs. It was about £4 delivered.
I then used an old motherboard header cable directly soldered to the TXD, RXD and GND points on the board above, and connected the other end to pins 3 (GND), 4 (TXD) and 5 (RXD) at the Texecom end. So in other words the data is received by the Texecom on pin 4, and transmitted from pin 5. Once this was all wired up I secured the board inside the casing with a cable tie and ran a USB lead outside the box.
The end result looks like this:
So a very cheap solution which is just as good as the £40 official alternative.
