instrument and automation system are selected from
the specified signals of the EIA-standard RS232 C,
corresponding with DIN66020 Part 1. The allotment of the
bushing can be taken from illustration.
• For the electrical properties of the interface lines and
for the allotment of the signal status, standard RS232 C,
corresponding with DIN66259 Part 1 applies.
