Connecting device between former ProComp+ and BioGraph 2.x software or other software systems (not from Thought Technology). Can also be used with the Procomp INFINITI with those software systems.
Connection is done through COM-port (serial port) which is getting more and more rare today in modern computers. Replaced by the new TT-USB adapter, that now connects the fibre optic cable to a USB port on any standard computer device.

NOTICE: For BioGraph Infiniti you USUALLY use the TT-USB adapter or the TeleInfiniti-System.
