1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

    'Behaviour

    Do not make inappropriate or offensive posts - including threats, harassment, swearing, prejudice, defamation, deliberate insults or name-calling, other negative remarks about this forum, its moderators and administrators or your fellow members. Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    Yes I have read that, seems it's only 1 brand of canister though that affects it, something to do with oil? Anyway, I'll avoid that particular brand (Crossman). I use the Umarex ones. :thumb:

    Hi Guys, I know this is an old thread but thought I'd let you all know my method. I used an USB adapter PL2303HX with the Pellet prog/app. Worked a treat for me, just make sure you get the pin connections right. If you search PL2303HX on Ebay they are only £3...

    thanks

    The pin outs are in the Combro instructions (pic). Red to 6V Black to 0V White to SOUT. I used a trimmed down RC plug lead (Futaba or similar) to make it easy to connect.

    If you open up that Combro instruction booklet, it shows exactly the same wiring diagram I posted above next to this picture , are you saying you've soldered a wire directly to those points on a USB plug and got it to work without the rest of the wiring involved . Or have you just soldered a longer wire onto the supplied USB plug that was custom made for the original Chronosoft cable/dongle ?

    That's why I was asking :), there's several USB to TLL converters , there lots of them that simply don't work , windows doen't recognise them :mad:, even on the website Robin states he's tried quite a few when people ask why he doesn't do his cable anymore, the chinese changed where the supplied voltage was supplied on the pins or something like that, I can solder A to B to C , but don't really understand exactly what the bits do just a slight understanding of what each bit is, his original fitted to a serial port I believe, I've got one, as well as one of each of the Chronosoft versions, one for phone and one that connects to the PC, I still stick to my Blueshot cable if I'm doing a complete cylinder test though, that doesn't seem to miss a beat, just keeps going right upto 150+ shots without missing anything.

    When I tried with the Chronosoft ones, despite being able to buy an extension, the actual cable is about a meter long, it just kept disconnecting either from the Combro or the phone, the shot string stops at that point, you have to reset everything and start a fresh, hence asking if you'd soldered a longer cable to an original.

    With the Blueshot , a small peace of tape keeps the cable fixed to the mod from the Combro, and away you go, obviuosly not so easy if it's on a springer as you have to keep loading pellets. either breaking the barrel or using the underlever, that's what made the Chronosoft ones worthless, they were used once or twice, never been out again :(. They just couldn't hack the loading sequence.

    When I have time (like now we all can't go to work :( ) No seriously, when I have time and the urge to rebuild something I'm not likely to use , maybe a better option if I sell my Combro's and send them with a working cable, I did actually buy some long USB cables to solder onto those points.

    While asking earlier Ganton gunner said if you make a patch cable that connects pin 1 to pin 3 , it forms a self resetting bridge , so you haven't got to keep pushing the reset button, but without software you'll only record the lowest shot highest shot and get an average of all the shots you've fired, quite enough info for some peolpe.

    I actually love my little Combro's , you can leave them fitted to you rifle, do a bit of target shooting, then see if those odd flyers are either severe spikes or drops in velocity , you can shoot a whole cylinder and see where the sweet spot is (non regged) and see where it comes off the reg or just drops off the unregged gun, depending on what software /cable configuration you are using :thumb:. Without having to shoot through any pipes, tubes or apertures , wait for the correct light to shine or anything else, they even work in the dark :thumb:
