megajolt connection to laptop
Turbo Mini Forums

ive just installed MJLJ V4 and i cant get my laptop to communicate with MJ it keeps saying "timeout reading cylinder count". i bought my USB serial converter from maplins could this be the problem

have you configured the MJ software to use the correct port?

Have a look in device manager (right click my computer, click manage, option on the left) and see what port the USB - serial adaptor has taken and configure that in the software.

Also, check the MJ unit is powered up.

yeh done all that its using COM 5 on the laptop and thats how ive configured it on MJ

Have you downloaded a driver for the chipset in the adaptor?

yeh the USB converter came witha disk with the driver on it and ive installed that so i think i may have to try another converter

i found it very hit and miss with the usb - serial adapters, i went through 3 before finding one that worked correctly and that cost 25 quid

Yes i moved to the darkside

I agree the USB adaptors are just aggro.

In the 13's at last!.. Just

neil, you still got that old laptop you lent me?
did you get it to run your MJ?

Yup, worked a treat. Although since then the screen has died.

i bought three seriel to usb connectors, first one didnt communicate at all, second one would crash all the time, i cant remember the make of the third one i bought but it was spot on, it was someone on here that told me the make and i bought it, worked stable and perfect with that one

I have exactly the same problem i have installed V4.0.2 and installed my usb parrallel reader but when i open up the software it shows in the bottom middle a message "timeout reading cylinder count" usb drivers are installed also, i have tried 2 diffrent ports on my laptop currently running windows vista, then have gone through the steps checked with multi meter the correct pins to the parralell port go into the mega jolt set correct com number (COM 10) and then applied a 9v
battery illuminating the light on the box started the program up again and still the same message

It might not be the issue in this case, but a lot of software routines don't accept COM port numbers above 9 on the USB/serial converters even though you can select and display them.

Allways try to use low COM numbers with these convertors.

They are also sensitive to which USB port you plug them into (if your laptop has more than one) and will often change COM numbers when plugged into a different socket and sometimes even need the drivers re-installing when this happens. I use three eBay specials (£1.50 each) and I have them all labelled as to which socket they go in on both laptop and desktop to avoid having to re-install the drivers every time I swap things around.

Schrödinger's cat - so which one am I ???

its sorted now i got a usb serial converter from trigger wheels and it works fine now

Nice to here its sorted Smudger, ive given up on the lappy and dusted off the descktop connected by parralell and worked straight away! :)
