2.3

Data Transfer

The logic of the optical interface is positive (Light OFF in idle state),
incoming light signals are treated as active = 1 (high). For use in systems
operating with a negative logic, the converter can be switched over to
negative logic by means of a switch that is accessible from outside.
Inversion of the logic applies to both the optical output and the RS232
interface output. On delivery, the converter is set to positive logic (Light
OFF in idle state).
2.4

Connection of the FO Channel

The FO cables are connected to the corresponding FO elements. The
connector type is BOFC (ST).
When wiring FO cables, the specified bending radius must be observed.
2.5

Connection of the RS 232 Channel

The RS232 channel is connected by a special RS232 cable with 9-pin
Sub-D male connector.

Terminal Assignment 7XV5100-4

The serial connection cable ´DIGSI-cable´ connects a 9-pole serial PC-
interface (e.g. COM1) with the serial interface of the relay or a
starcoupler or a converter, which have also a 9-pole serial interface..
The following devices have a 9-pole serial interface: 7SJ531, 7SJ602
and all SIPROTEC 4 devices, e.g. 7SA522, 7SD52, 7SA6x,
7SJ61/62/63, 6MD6x, ... . In addition the starcouplers 7XV5300,
7XV5450, 7XV5550 and the converter 7XV5652 are directly connected
with this cable.
