SigLite 1x5 Model:T-S460-B (with serial connector)

The problem was not the topaz pad but my laptop. I removed all software which needs the serial port and I finished all not necessary programs which were running in the back but the problem was still alive. Now I asked my administrator for more rights and I changed the name of the port from port "1" to port "3" (port "2" doesn't work). I've got the message "port 3 is already in use" but the pc accepted the exchange of the name. Afterwards I changed the portnumber in the ini.file of the Topaz Software and now it works without any problems... strange, strange.... my five colleagues who are using the same pad on the same type of laptop (Compaq nc 6120) haven't got any problems during installation of the pad.
Thanks for your interest - kind: regards Ben Gun
