STR 100 - Signal Transducer
2 STR 100 SYSTEM
2.1 DESCRIPTION
STR 100 is modular system of communication devices that can be used for various of tasks
such as:
distance protection criteria transfer
disconnector and circuit breaker statuses transfer between substations
signal transfer via communication through noisy industrial enviroment
status and command transfer for remote switch
2.2 FEATURES
Wide range power supply
Digital input voltage suitable for substation's power supply
RS232, RS485, Fiber Optic or Ethernet communication interface
Switch selected BAUD rate
4 digital inputs
4 dIgital outputs
DI 35 rail mount
Short response time
2.3 FUNCTION
Two devices from STR 100 system works in pair. Input statuses from one device are transfered
to second device outputs and vice versa.
Devices are coupled through full duplex commnication link. Communication is based on special
protocol. If communication link is broken DO statuses of both devices are returned to theirs inital
states. Speed of communication can be selected by switches.
One of DOs has two functions. It can operate as normal DO or as communication failed
signalization. Selection between functions is made by switch.

FU CTIO
All normaly used connectors, switches and light indicators are accessed at the front side of the
device. One light indicator indicates power supply voltage, others indicate communication and
IOs activity.
2.4 TYPICAL APPLICATION
Typical application is transfer of trip command and circuit breaker status between two
substations.

STR 100 - Signal Transducer
4 HARDWARE DESCRIPTION
Hardware is based on main board (power supply), interface board and IO board (DIs and DOs).
4.1 MAIN BOARD
Main board provides neccesary power to other parts of the device and place for interface board.
On the board there are also three LEDs. The yellow LED shows activity on receive (Rx) line and
the green one shows activity on transmit (Tx) line. Additional green LED indicates the device
power supply activity.
User can choose between two main boards:
HI – high voltage power supply board
MD – medium voltage power supply board
LO – low voltage power supply board

Phoenix MSTB 1 2
Description L- , L+, L1
For further technical data see chapter „TECH ICAL DATA“.
4.2 INTERFACE BOARDS
User can choose between following interface boards:
RS232 board
RS485 board
Versatile link plastic fiber optic board
Multimode Fiber Optic (ST connector) board
Singlemode Fiber Optic (SC connector) board
Singlemode Fiber Optic (FC connector) board
Singlemode Fiber Optic (ST connector) board
Ethernet board
Although STR 100 device can have two interfaces it can communicate only with one at the time.
Data is always received and transmited to both interfaces (ports).
4.2.1 RS232 INTERFACE BOARD
Description
Single, nonisolated, full duplex, RS232 port with DB9 female connector. Supported Rx, Tx and
G D pins.

4.2.2 RS485 INTERFACE BOARD
Description
Single, galvanically isolated, half duplex, RS485 port with Phoenix 3 pin screw connector, with
automatic switch to receive after end of transmission and with additional terminating and
stabilizating resistors.
Hardware settings
For proper functioning of that board some settings must be done:
RS485 bus termination and stabilisation
baud rate
RS485 bus termination and stabilisation
TERMI ATIO
At high transmission rates or long distance, RS485 bus termination is necessary.
The termination on RS485 bus must be set on both ends of the RS485 bus.
STABILISATIO
Some device, to work properly, demands that RS485 must always be in known and valid state.
That is, when + (positive) pin is more than 200 mV positive than – (negative) pin. Pins + and –
are sometimes marked as A and B. In case that no device on RS485 bus is transmitting or in
case of short circuit, there is no voltage difference between those pins and some device do not
work correctly.
On this port board so called „true fail-safe“ RS485 chip is used so board works correctly without
stabilisation at invalid RS485 bus state. But still switches for stabilisation are provided on port
board. The stabilization on RS485 bus may be set on one device only!

BAUD rate setting 19k2 (bps) is valid for all standard communication protocols, that do not
request special timings. If special protocols (small request-respond time required) are used
please note it in order.
NOTE! If there are problems with communication, try using higher speed setting. Some
manufacturer have different markings for B and A line. Try to switch A and B wires. See
http://en.wikipedia.org/wiki/RS-485 for detailed information.
