If you follow the tutorial to the letter, you shouldn't have that problem

It is unlikely that the null cable is at fault, and this is normally the case when making an error.

Is your null cable showing up in device manager? Easy way to get to it. Click Start>Run and copy and paste: devmgmt.msc

Should get you there as soon as you press enter. On a side note, be sure to upgrade XP to Windows 8 when it comes out later this year. It's more resource efficient than Windows 7 so should be good for XP machines (as long as you have the hard drive space)

cheers,i will try that shortly,also does the null cable need to be rs232 straight or reverse or does it matter,THANKS AGAIN.

waqasahmed · 02-02-12, 05:13 PM

RS232/ straight should be fine. I don't think I've heard of a null modem "reverse" cable. As long as you have a null modem cable and not an ordinary RS232 or a console lead, youll be fine

stranded · 02-02-12, 05:54 PM

Hi waqs, i was asking about the null cable because in maplins there is one for straight data/firmware or reverse which means send and receive,so the box does not send any info back? CHEERS AGAIN

I suppose it wouldn't matter though remember you are getting ripped off at Maplins. You are downloading on to the box, and if you want to upload channels, you could do so with the "reverse" null cable. Though Im guessing here as I've never heard of a "straight" or a "reverse" null cable before until now

When you do go in to device management, could you have a look see if you have any question marks. Could you also look under ports (COM & LPT), if you don't have any question marks.

The clock rate of the serial link may need changing, or it might not need to, so that's something to check. Try to see if you can change the details to the following:

bits per second 115200
data bits 8
parity None
stop bits 1

You should be able to do this by right clicking your COM port and clicking on properties

If this doesn't work, then you may have been mis-sold a cable by Maplins and this should work:

A Null Modem cable is the cross over type as opposed to a serial (straight) cable, you used to connect a modem between two computers when transfering data with a straight cable thats why the crossover one is called a null modem.
The link waq posted is the right type, you can connect your box to your friends one and update.
