Unpacking and Repacking
The devices are packed at the factory to meet the requirements of IEC 60255–21.
Unpacking and repacking must be performed with the usual care, without force and only
with the aid of suitable tools. Visually check the device immediately upon arrival for correct
mechanical condition.
Please also always follow instructions if they are supplied with the device.
The shipping packaging can be reused in the same manner for further shipment.
The storage packaging of individual devices is not sufficient for shipping.
If other packaging is used, the shock requirements acc. to IEC 60255–21–1 Class II and
IEC 60255–21–2 Class 1 must be met.
The device should be in the final operating area for a minimum of two hours before the
power source is first applied. This gives the device time to attain temperature equilibrium,
thus avoiding dampness and condensation.
Storage
SIPROTEC® devices and associated assemblies should be stored in a dry and clean place.
The device and its replacement modules must be stored within the temperature range –10
°C to +55 °C.
The relative humidity must not cause condensation or ice.
To avoid premature ageing of the electrolyte capacitors in the power supply unit, a
temperature range of +10 °C to +35 °C (+50 °F to +95 °F) is recommended for storage.
After extended storage, the power supply of the device should be energised, approximately
every two years, for one or two days to regenerate the electrolytic capacitors in the power
supply unit. This should also be done before the device is put into service.

Application
General scope of application
The Serial Hub is designed for operation in industrial zones and substations.
The Serial Hub enables devices with serial interfaces (RS232, RS485, or FO) to convert
data to the UDP protocol and to transmit and receive it via a TCP/IP network. This allows
devices without dedicated network ports to exchange data via the Ethernet.

9 / 53 C53000-G1176-C174-3
Application in Substations
Using a 7XV5655-0BA00 Serial Hub with a fixed IP address, one or more SIPROTEC
protection units can exchange serial data via an Ethernet network.
On the operating PC, a configuration tool is used to link virtual COM port with the IP
address of a Serial Hub. Using DIGSI 4 it is then possible to operate all protection units
connected to the Serial Hub via the virtual COM port.
The protection unit is connected to the Serial Hub via its serial interface. The serial interface
types available are RS232 or RS485 (same connector), and FO (fibre optical). The serial
data are converted to the UDP protocol with error detection and correction as useful data in
the Serial Hub and transmitted via the TCP/IP Ethernet network.
The hub meets the requirement for standard compliant, uninterrupted transmission of serial
DIGSI®or IEC 60870-5-103/101 frames via the network by listening into the serial frame
traffic and sending the serial IEC telegrams via the Ethernet packed in blocks. Both full-
duplex and half-duplex data transmission (RS485) are possible. The serial control lines are
not supported. The Serial Hub can be configured with password protection.
Configuration of the Serial Hub is performed using the configuration tool included in the
scope of supply.

Description of Interfaces, DIP Switches and Displays
The Serial Hub has the following connectors:
•A switchable RS232/RS485 interface (9-way SubD male connector)
•FO transmitter and receiver port with ST connectors
•10-Mbit Ethernet connector (10BaseT) for a 10/100 Mbit network
•DIP switches for RS232/RS485 switchover and RS485 termination and for setting the
FO idle state
•AC/DC power supply and protective conductor (PE) connection via 3-way screw
terminal
Communications Interfaces
The RS232/RS485 or FO interfaces are controlled internally by the same processor
interface. The electrical interface is selected via the DIP switches. You can choose between
RS232 or RS485; the FO interface always works parallel with RS232 or RS485 at the
transmitter end and is ORed with RS232/485 at the receiver end, that is, both streams of
receive data are unlocked and are received and evaluated with equal priority. To rule out
data collisions, the connected protection units are addressed selectively by DIGSI®. This is
done via the interface address of the protection units.
RS232 Interface
The terminal device (protection unit) (e.g. a
SIPROTEC®4 unit) or a device from the
SIEMENS accessory program (e.g. a 7XV5300
or 7XV5450 star coupler for operating two or
more SIPROTEC®devices) can be connected
directly to the RS232 port. The data is
exchanged between the protection unit and the
Serial Hub via this interface.
To use the RS232 interface, DIP switch S2-1
must be set to RS232 and DIP switches S1-
1+2 to (RS485 termination) OFF. The DIP
switch for the FO idle state (S2-2) must be OFF
(see Fig. 3).
Note: The factory settings for all interfaces are 9600 baud / data format 8N1. The settings
are automatically adapted to the terminal device's interface by the application (e.g. DIGSI)
on connection.
Fig. 3: Connectors and DIP switch positions
RS232

English 7XV5655-0BA00
12 / 53 C53000-G1176-C174-3
RS485 Interface
The bus-capable RS485 interface provides a
more noise-immune link than the RS232
interface. The data transfer rate is identical
for both interfaces. The terminal device (e.g.
SIPROTEC®4 device) to be operated or up
to 30 further bus-capable SIPROTEC®
devices are connected directly to the RS485
port.
To use the RS485 interface, DIP switch S2-1
must be set to RS485. The position of DIP
switches S1-1+2 depends on whether a
RS485 termination is required or not (the
termination is set to ON as the first or last
device on the RS485 bus).
The DIP switch for the FO idle state (S2-2)
must be OFF for idle state = OFF (see Fig.
4). For RS485 mode, "half-duplex" mode
must be set using the configuration tool (see
p. 36 RS232 Interface Settings)!
FO Interface
The FO interface has a transmitter and
receiver port with an ST connector. It is a
noise-immune link and is used whenever
especially high interference levels are to be
expected in the operating environment or
when equipotential bonding with the
terminal device has to be avoided. The data
transfer rate is that of the RS232 interface.
The terminal device (e.g. a SIPROTEC®4
unit) or a further device from the Siemens
accessory program (e.g. 7XV5300 or
7XV5450 star coupler for operating two or
more SIPROTEC®devices) can be
connected directly to the FO port.
Note: The FO interface is always active
with the RS232 interface; the DIP switch
(FO-OFF/FO-ON) only sets the idle state.

RS485
Fig. 5: Connectors and DIP switch positions FO

English 7XV5655-0BA00
13 / 53 C53000-G1176-C174-3
To use the FO interface, DIP switch S2-2 must be set to match the FO idle state of the
communications partner (ON or OFF). DIP switch S2-1 for RS232/485 selection must be
set to RS232. DIP switches S1-1 and S1-2 must be set to OFF (see Fig. 5).
On SIPROTEC units, the idle state is preset to OFF. This is also the as-delivered state of
the Serial Hub.
The 9-way RS232 interface can be used in parallel. If it is not, please cover it with the
red protective cover supplied !
If the FO interface is not used, it must also be covered with the protective covers supplied.
Ethernet Interface (10BaseT)
The Ethernet interface 10BaseT (RJ45) is connected via an Ethernet patch cable (1:1, not
cross-over) directly to the output of a router or switch. The data packed in the UDP protocol
are transmitted to and received from the Ethernet via this interface. The Serial Hub can be
configured using the configuration tool on a PC connected to this network via a straight
patch cable.
Using the configuration tool on a PC with an Ethernet interface and a cross-over Ethernet
patch cable connected directly to the Serial Hub, it is possible to configure the Serial Hub,
too.
The configuration tool is included in the scope of supply.
Auxiliary voltage
The auxiliary voltage Vaux (AC/DC) and the protective earth conductor are connected via
three terminals. The wide-range power supply unit has reverse polarity protection (terminals
L+ and L- could be swapped in AC and DC operation) and can be used in substations with
substation batteries, for example. It features double or reinforced insulation and backs up
the auxiliary voltage for >50ms.
GOK Contact
The isolated GOK contact (device run) is for signalling faulty device states. The device
internally monitors the supply voltage and proper functioning of the device.
The contact is open in the normal operating state and closes on faults and auxiliary voltage
failure. It is connected via two terminals (GOK 1+2).

English 7XV5655-0BA00
14 / 53 C53000-G1176-C174-3
INIT button
The INIT button is for resetting the Serial Hub to its factory (default) settings and should
only be operated by technically qualified personnel.
It can be used to set a defined baudrate locally for service work. The default baudrate is
9600 8N1. The Serial Hub also outputs a reset string with the date and version number of
the firmware on its serial interface (RS232 / RS485 / FO).
This reset string can be read by a terminal program (e.g. HyperTerminal in Windows) on a
connected PC. The serial interface of the PC must be set to the default baudrate.
You do not need to use the INIT button if you know the baudrate!
Operating the INIT button does not change any settings relevant to security such as IP
addresses or password!

Preparing the Operating PC or Service Notebook
Before commissioning the Serial Hub, you must take the following precautions on the
service PC (notebook).
•Installation of the hub driver
To operate the Serial Hub from a WINDOWS® application in which an Ethernet link
will be established, a driver providing a virtual serial COM port must first be installed
using the configuration tool. This is done by installing and setting up the
configuration software.
From the point of view of the application, the virtual COM ports look like interfaces
built into the PC/laptop. Up to 255 virtual COM ports (minus the number of physical
COM ports) can be installed on a PC/laptop.
This requires the operating system WINDOWS® 2000 or WINDOWS® XP SP1
(Home / Professional).
•Installing the Configuration Software
For easy Serial Hub configuration using the configuration tool, the tool must be
installed on the operating PC from the enclosed DVD “SIPROTEC DOWNLOAD-
AREA offline“ under "Accessories \ 7XV5655 \ Configtool".
There are two ways of configuring the Serial Hub using the configuration tool via the
Ethernet interface.
1. The Serial Hub is connected directly to the operating PC/laptop using a cross-
over patch cable. After you have started the configuration tool, the connected
Serial Hub is found automatically and can be configured.
2. The Serial Hub is connected with a patch cable to a switch in an existing
network to which the operating PC/laptop is also connected. After you have
started the configuration tool, all connected Serial Hubs are found
automatically and can be configured. To configure Serial Hubs that are in
another network segment (e.g. behind a router), they must be located in the
network by manually entering the IP address.
•Configuring the Ethernet Interface of the Operating PC
For the operating PC to be able to communicate with the Serial Hub, the Ethernet
interface of the operating PC/laptop must be configured accordingly.
