I finally had some time this weekend to hook my logic analyzer up to the IEEE port and try it again. I was able to get the CLR command to work, but the IDN? Returned nothing. I dug into the error and it said, device not listening. I have 2 logic analyzers (I found 1 96 channel one for $60 with cables, pods and clips. How could I pass that up????) and I will try the other one this weekend. One thing was strange though. In the IO config, it did allow me to select IEEE as an option and config the port number. So, something is preventing it from listening. I searched the other screens for places to configure it and came up blank. Also, I am running the latest firmware that has the mouse support.Do you get a response to *IDN? via your IEEE interface?
Somewhere I read that there was an IEEE upgrade kit by Philips. I wonder if this included a set of new EPROMs.
I'm aware of the Util disk. I used it after replacing the battery. The mouse is working fine. Unfortunately, there is only one RS232 interface, so I can either use the mouse or communicate via RS232, but not both at the same time. Therefore, GPIB would be very nice.
Communication via RS232 works fine though, but rather slow at max 19k2 baud.
Btw, I wrote a windows software to convert screen dumps to bmp or jpg. Might be useful for others, too, see attached result.
