Hi Mate
Now.. what i found out was this
When you run the DS2000A Upgrade Utility
and you get past the screen where is loads the Custom Firmware onto USB
and then you required to plug in your DSO, but it doesn't detect
HERE'S THE DEAL
You need to go to UTILITY\USB DEVICE
You have 3 visible Items
Auto Detect
Computer
PictBridge
Now (AT LEAST ON MY SCOPE) it seems that only the last 2 are selectable
I guess (and it is just a guess) that it's always in Auto Detect Mode
I did some further reserach
i downloaded the Manual which is available here
http://www.rigolna.com/download/501G00000001PKXIA2/and the relevant page is ........ 14-6
it reads as follows:
============================================================
USB Device
This oscilloscope can communicate with PC or PictBridge printer via the USB Device interface at the rear panel. You need to set the oscilloscope to make it match with different device types.
Press Utility - IO Setting - USB Device and use (Intesity Knob) to select the desired device type.
- Computer: in this type, the oscilloscope can communicate with the PC.
- PictBridge: in this type, the oscilloscope can communicate with the PictBridge printer.
===============================================================
Going off that
i would guess to say that the Manufacturer has it in AutoDetect Mode always, but you can force it to Communicate with a Port at will
Mine was in PictBridge Mode when i had the problem
that was most likely as a result of my other Engineer freind who came over the evening and who owns an Old 7 Year old Tektronix Digital Scope
He must have changed the setting without me realizing it.
But.. I'm unable to actually manually select Auto Detect
and i've tried going through the scope to find other relevant settings that may Cause this item to NOT BE GREYED OUT
have not had any luck finding such an item
will continue to tinker with my scope, and if i happen to find a way to do it, i'll post it,
but, going off the manual i'm guessing that won't happen.
Hope this has helped you
let me know if you need any further assistance
BE COOL
