CMU 100 SYSTEM
2 CMU 100 SYSTEM
2.1 DESCRIPTION
Communication unit (CMU 100) is modular system of communication devices that can be used
for various of tasks such as:
communication converter (for example RS232 to RS485)
star coupler (for example 1 fiber optic to 7 fiber optics)
repeater (for example RS485/485)
communication isolator (for example for preventing ground loops)
communication listener - debugger
PC serial com port extender (for example USB to 4 serial com)
CMU 100 device is a couple of software and hardware. or 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
Hardware is based on main board with power supply and port switching logic. On that board,
interface boards are attached. CMU 100 can handle up to 8 different interface boards. Currently
available interface boards:
RS232
isolated RS485
Multimode iber Optic with ST and SMA connectors
Singlemode iber Optic with SC connectors
Versatile Link iber Optic
USB
ethernet (with one virtual com port)
Housing is aluminium and intended for mount on standard DIN 35 rail (acc. to DIN EN 50022). 3
different housings have been made. Depends on how many interfaces device has, appropriate
housing is used.
Hardware settings
All settings on the device can be made from outside by a DIL switch. It is not necessary to open
the housing.

RS485 TO SINGLEMODE IBER OPTIC CONVERTER
3 RS485 TO SINGLEMODE FIBER OPTIC
CON ERTER
3.1 DESCRIPTION
This device allows communication between two devices with different communication interfaces.
It contains one RS485 and one 1310 nm wave lenght singlemode fiber optic interface. Data is
send from multimode fiber optic to singlemode fiber optic and vice versa simultaneously. Device
allows data speed up to 115,2 kbit/s. Singlemode interface range is approximately 20 km.
Wide 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 front side of the device. One light indicator
indicates power supply voltage, others indicate communication transfer.
iber optic communication allows longer distances between devices without electromagnetic
disturbances.

HARDWARE DESCRIPTION
RS485 bus termination and stabilisation
baud rate
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!

BAUD rate setting 19,2 kbit/s 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
