I'm in the UK, using the Keil C51 toolset, and the Triscend E5. Being in Europe (or, should I say, outside the USA?) I have to use a "dongle" (hardware key) with the Keil tools. Far from being transparent, the Keil dongle seems to significantly mess-up the communication bewteen the parallel port and the Triscend JTAG. Keil's knowledge base article http://www.keil.com/support/docs/1788.htm suggests that this may not be an uncommon experience. Has anyone else experienced problems with the Keil dongle - particularly in connection with the Triscend E5? Any tips?
We have a Dell laptop, with an external disc drive. The external disc drive will not function with the Keil Dongle in place (if anyone has any suggestions as to how to get round this - it would be appreciated). This is a minor inconvenience though when compared to the problem of forgetting your dongle when going on a site visit to commision software/hardware. Put it this way though - you only tend to forget once! Yours, Richard.
We had the same kind of problems with a Dell laptop and data I-O chiplab programmer. The dongle short circuits pins 17 upto 25 (as GND pins) but Dell uses some of them to see if a external drive is connected. So you should wire these pins around the dongle. you should keep ONE GND connection in place, obviously. Good luck- Alex.
