V.24/TTY Converter
This chapter is only intended for specialists interested in the
structure and technical data of the interface converter required to
convert the V.24 port of a PC used as a PG to an active TTY
interface.
The data exchange with the programmable logic controller or the
point-to-point link with another PG requires an active TTY
interface (20 mA current loop) as the COM interface.
If the existing COM 1 port is a V.24 port, the “PLC-S5” interface
must be simulated by an S5 converter.
The company Köster GmbH has developed a special V.24/TTY
converter for PCs (known as the Köster box).
