Function
The converter is directly plugged to a 9- contact serial interface of a PC.
It converts the RS232 signals of the PC into standardized RS485
signals. This conversion enables to simultaneously connect several
devices by a 2 - wire junction to one interface and to inquire one after
another.
The device is protocol - transparent, i.e. the RS485 signals are trans-
lated 1:1 into the signals of the RS232 interface.
Depending on the 2 - wire junction of the RS485, a half- duplex opera-
tion only will be possible. This means, only one device may send in the
network at a time. By that a simultaneous operation of sending and
receiving will not be possible.
