VP-598 and NVR2 2k*8 Reading Reply  
handsome
Pekka
Hey, I am repairing old German automatic tool machine. .
It has parameters in NV ram NVRZ 2k*8. I can"t read it and save it so that I can replace old RAM with a newer M28Z02.

How I can set your programmer that I can read the old ram? 
Regards
Pekka Ritamaki Finland

Hey, I found E/Eprom device, which can read my M48Z02 and write my devices although it is not just right. Still I wonder why I can"t read with SRAM devices?

VP-996 programmer not seeing adaptor Reply

I have a VP-996 Universal programmer
I can program EEPROMs with it
however, when I tell it to program my 68pin CPU through an adaptor I get this message:

>>Do not find Adapter! Set Adaptor: Run <Read> without chip on the adapter!

The CPU I am trying to program is a pic17c756a-33/L.
This is a new error for me, I have used this exact programmer/adaptor combo many times before.

No matter the config/settings, or if the adaptor is even plugged in, same message

Has anyone solved this?

Hi,
I am programming an AMD AM27C400 with the VP-299 - I get the message:

Any ideas as to what this error is?
The chip programs fine on the VP598 my dad has.
Other chips program fine on the VP-299 - so it looks like possibly a software problem
Kind regards

Hi.
I"m having trouble reading and writing the texas instruments M430FG4619 by ISP.
In the wellon software we have the option MSP430FG4619 for ISP.
Am I selecting the correct component in the wellon software?
The software returns the reading successfully, but with all FF data.
I followed the connection diagram on the component pins as instructed in the ISP manual of the WELLON software.

Thank you all.

Hello,

I"m having a problem testing a SN74HC74N IC. When I open the test page, the software says "When testing 14 pin devices connect a line between P27 and P28".

The problem is, if I do connect a line between P27 and P28 the test FAILS. If I dont connect the line the test passes. The IC is brand new and working, so I know it should pass the test, but it doesnt pass if I connect the line as instructed by the software.

What is wrong here??

Hello,
I"ve read mcu MC9S08SH32 through vp998 in isp mode. In the files it shows that the mcu is 32kb but the information I put in was 164kb. What is the explanation of this?

Hello, colleagues!
I have your programmer WP-390.
When I want to read M27C256,
I get a Programmer trouble! ID error: 39AA37BE1400002B.

I check + 5v in the self test and get 4.45v without a power supply,
and 4.85 with a power supply.

Has anyone encountered such a problem?

My VP299 is programming ATF16LV8C chips fine, without AC adapter. When trying to program ATF22LV10C chips it asks for an AC adapter. When I plug this in and try to program, it reports "Over Current Detected!".

I don"t think it"s the chips. They are brand new and I tried more than one. What could be the problem?

Increasing the value of the resistor is to promote the band of protecting circuit.It"s no problem for other chips.Also, the screws are under the rubber bumpers.
