IEEE 1394 Drivers

IEEE 1394 Driver issues

As I worked with the Flex 5000 I have come to suspect the IEE1394 adapter card and it's drivers as the source of issue for the unit continuing to enter the "off" mode repeatedly and with no warning or seeming outside intervention.  Reading some of the other user groups points to the drivers not being 100% compatible with Windows 10.  I have followed the instructions to install the legacy drivers for the card, a TI based chipset.  

It is at the state now that it will seemingly randomly work for minutes or hours before shutting off.  

I have read that Windows will "automatically" shift the drivers for the IEEE1394 card back to the Windows10 ones that do not work well.  Today I want to check to see if that is the issue, or not.  

Method:  

Note the current version of the driver.  

update the driver (see what happens) 

Check the version of the driver and operation. 

IF not acceptable, re-install the legacy drivers previously downloaded.

Here is our starting point. 

First,  Use windows Update feature.

Well, it ought to have tried to update, as I thought I had the legacy driver installed.  text

So, now that this is documented, I will now apply the so-called "latest" legacy drivers previously downloaded from MS site:

File name is:  1394_OHCI_LegacyDriver.msi  

Sorry, I cannot save files to this blog.  I think.  

But, I can provide a link from Google Drive:

It worked when I tested it.  No promises down the road....

First I will try to "update" by pointing to the MSI file, that is an installer file, so I doubt it will work.  

No, it did not work.  

I will run the MSI

You don't see a helluva lot.  It blinks, a status info window opens and closes in about 100msec.

reboot computer.  

IEE card is there, and the same info.  Nothing apparently changed

running Power SDR for hte Flex 5000m 2,8,0,169   Hmmmm, it took longer than normal.....

Let's start, this time, by only running it.  No WSJT-X or associated apps.  

Hmmm, seems just fine, other than all the bands are dead today. 

After Two days of the radio running, there was no interruption in the operation of the connection.  It looks like the Firewire connection to the radio is NOT likely the problem.  

Isomac Boiler Autofill Issue

Symptom:  Only water comes out of the steam wand, pressure on coffee is 4 bar maximum instead of the normal 9 or more bar.

Occurence:  The boiler is filling above the design level to the point that only hot water is available from the steam tap.  Coincident is that the pressure on the group head does not rise above 4 bar.  

Cause:  The boiler autofill solenoid valve has partially failed in the open position.  

Other cause could possibly be the Geimme controller is calling for the solenoid to open while pressing a coffee.  This should not generally happen.  

In this case, draining out the excess water and cycling the group head and pressure pump with the blank filter basket in place seemed to clear up the symptom.  I am ordering a new solenoid valve.

My machine is 120V so this version would not work for me.  

I am looking for the best price on the solenoid.

Hah: Found a Canadian source for 40% less bucks.  OOPS wrong base.  This one will not work.
