2 CMU 200 SYSTEM
2.1 DESCRIPTION
Communication unit (CMU 200) is modular system of communication devices that can be used
for various of tasks such as:
communication converter (for example 20 channels RS232 to Fiber Optic converter)
star coupler (for example RS232 to 39 fiber optic)
CMU 200 device is a couple of software and hardware. For different purposes, different software
versions and different hardware configuration have been developed.
2.1.1 SOFTWARE
Software is application dependent and allows different hardware configurations. Software's task
is switching between communication ports and allows almost any combination between them.
2.1.2 HARDWARE
CMU 200 can handle up to 40 different interface boards. Currently available interface boards:
(non)isolated RS232
isolated RS485
Multimode Fiber Optic ST or SMA connectors
USB
ethernet (with one virtual com port)
power supply
There is possibility to use additional redundancy power supply.
Housing is made from inox and is intended for mount on standard 19"rack.

DESCRIPTION
3 DESCRIPTION
3.1 DESCRIPTION
Star coupler is communication device that transfer data from one (master) to more than one
(slave) port.
This device contains 1 RS485 and 39 multimode fiber optic ports. Data is send from master port
to all slave ports. On the other hand, data from either slave port is send to master port only.
Power supply voltage allows connection to all common station batteries. Additionaly it can be
also connected to standard AC voltages.
This device is intended for use in cubicles and cabinets in all kinds of power production,
transmission and distribution stations. It requires no maintenace. All normaly used connectors,
switches and light indicators are accessed at the back side of the device. Two light indicators
indicates power supply voltage, others indicate communication transfer.

3.3.2 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

HARDWARE DESCRIPTION
RS485 bus termination and stabilisation
TERMINATION
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.
STABILISATION
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!

Switch 4 5 6

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.
