User's manual for OPTO-RS cable connections
General
The OPTO-RS cable enables a direct connection with most of the Käfer measuring instruments to a personal
computer, a dedicated printer or to a Käfer display unit.
It is not only a cable, but an interface which converts the data output of the instrument to a compatible RS232
signal. The periphery instrument connection must be able to supply power to the OPTO-RS plug.
