It is not in the list so I created it with add pattern consulting its datasheet, I resulted:

v1:0L00LL00LG1L00LL00LV
v2:0H11HH11HG1H11HH11HV
v3:0L00LL00LG0L00LL00LV
v4:0H11HH11HG0H11HH11HV

where I thought to leave out 2 tests, because I could not interpret the state "high impedance state off" for output

naybe your programmer is bad. this programmer is elder product.

I have two issues:

1 - How do I get it out of "demo mode"

2 - Should it have an ac adapter plug? I use the USB cord and I assume it is getting power because the green G/E light is illuminated.

I have a VP-996 programmer and I am trying record an AT89S2051 soic, if I use an adapter with paralel mode it works, but if I try with adapter ISP with the cable It works ( read, prog config, compare) but doesn´t erase and doesn´t program, when I interchange MOSI per MISO, Erase It works, only program doesn´t works, I upgrade my version today 4.6.5,the message it´s:

I am a newbie and I need help please:
Bought a VP-190 programmer and want to "copy" a NS NM27C32BQ Eprom.
Select done (NMC27C32B - without "Q").
Original Eprom inserted - read (under 1 second) - saved as .bin.
New Eprom inserted - Prog - Warning! Device Code Error - Man.Code:FF Dev. Code:FF

Any idea???

NMC27C32BQ = NMC27C32B maybe your chip is bad.

I have problem with reading AM29LV017D memories. When I place memory in adapter and start reading, programmer indicates problem with memory connections (few pins blink): http://www.wrkom.pl/am29lv017d.jpg I was trying to clean pins of memory but it doesn`t matter, all connections are good. My memory is in standard TSOP40 package and I am using pin to pin TSOP adapter. Ofcourse adapter works fine with other types of memories, problem is only with AM29LV017D. Can you help me?

I try to read a hex file to buffer but the buffer is empty. From user
manual, it should have a dialogue window open but it have not. 選中檔後，將會彈出一個對話方塊（見5.1.1），點擊“確定”完成檔的讀入。
I also try to read 89c52 to buffer, it is the same. At last, I remove the software and reinstall. It is no difference at all.
Have any setting I have missing. Please advice

Tell us what programmer? what adapter? And which version of wellon software you used?

Last post : Re:problem ID Programmer VP990	Reply: lxl
1. download new software. 2. Run software, 3. exit wellon software. 4. run \\weilei\wellon\wellon_reset.exe. 5. if "system updated OK!",your programmer reset.
