Connection for 2 Binary Signal Transmissions and RS232 Connection for 1 Binary Signal
Transmission
The application shows the optical connection of an I/O mirror to a communication converter (KU-2M) 7XV5662-
0AD00, which establishes a connection to a multiplexer with G703.6 interface (1.44 kbit/s/2 Mbit/s, T1/ E1). The
KU-2M multiplexes and demultiplexes synchronous or asynchronous serial signals on up to 3 inputs on a
2 Mbit/s remote connection.
Transmission between binary signal transmission and KU-2M takes place interference-free via 62.5

μ
m multimode optical fiber. The fiber-optic cables are prepared with ST plugs. Additionally, the KU-2M is
provided with an electrical RS232 interface. On this interface, an additional binary signal transmission with a
max. of 115.2 kbit/s can be connected via an optoelectronic converter. This ensures that 18 binary signals can
be exchanged bidirectional via a G703.6 connection. The electric G703.6 connection to a multiplexer is per-
formed via short distances.
KU-2M has a wide-range power supply unit of DC 24 V up to 250 V and AC 115 V/AC 230 V.
The asynchronous baud rate in the binary signal transmission can be set to 115.2 kbit/s.
The KU-2M has 2 optical input interfaces. This makes it possible to transmit a maximum of 12 individual signals.
In addition, the device also has a RS232 interface. Via a RS232/optical converter 7XV5652-0BA00, a binary
signal transmission can be additionally connected. The distance between converter and KU-2M must not
exceed 3 m, since it is a serial electrical RS232 connection (you should preferably use visual interfaces). Using
all input interfaces (2 FO, 1 RS232) of the KU-2M, a maximum of 18 individual signals can be exchanged bidi-
rectionally.
Siemens recommends the 7XV5100-4 cable (DIGSI cable) with gender changer (9 pin male/male) as RS232 -
KU-2M connecting cable.
