Universal bus unit CoRe01

1400-9670

The unit can be used as a converter (RS-232 to RS-485) or asa repeater for RS-485 buses in two-wire or four-wire technology.
Slide switches accessible from the outside allow operators to
select the operating mode, transmission rate, termination andbus bias voltage.

USB/RS-232 adapter

8812-2001

Communication cable

1400-7419•• Approx. 1.5 m•• 9-pin SUB-D connector and RJ-12 connector
Programming cable

In two-wire operation, the polarity of the two wires does notneed to be observed, provided this applies to all other deviceson the bus as well.

•• Approx. 1.5 m

Both interfaces are isolated against the microcontroller (signalprocessing unit) located in between them. The interfaces do
not need to be used in the same operating mode, e.g. one interface can be operated in two-wire connection with 19,200
bit/s and the other in four-wire connection with 9,600 bit/s.
Despite connecting several repeaters in succession, the signal
does not increasingly degenerate.

•• For rail mounting

A safety mechanism (transmission time monitoring) prevents
the bus line from being permanently blocked.
Multi-function modem DataMod 11

1400-8801

The multi-function modem allows data to be transmitted between a control station and TROVIS 5500 Controllers over along distance using public telephone networks. The built-in
line splitter enables several controllers to be addressed in one
common phone link without the use of a coupling computer.

The multi-function modem has three ports (RS-232, TTL andRS-485). Alarms can be sent as text messages to a mobile
phone, provided the controller supports this function.

Communication
Two versions (four-wire or two-wire system) are available forthe communication with the RS-485 bus signal level between
various components in a centrally controlled system.
The two-wire system has two bidirectional data lines to transmit data (TD) and to receive data (RD).
The four-wire system has four unidirectional data lines, twolines to transmit data (TD) and two lines to receive data (RD).
Network structure (see following pages)
First connect the converter to the computer to convert the RS232-C signal from the computer into the RS-485 bus signallevel. Should the total line length exceed 1,200 m or morethan 32 stations are connected to the bus, a repeater must beused. It is not recommendable to use more than five repeaters
connected in series. The bus lines should branch directly at thebus participant, if possible, or at the hub. If this is not thecase, a repeater must be used. A bus termination must beused at the beginning and end of each physical line in order
to discharge any interference voltage.

Lightning and overvoltage protection
Upon installation, observe the relevant standards and regulations governing lightning and overvoltage protection. For datatransmission lines running between buildings, lightning andovervoltage protection must be ensured by the appropriatemeasures. In addition, sufficient equipotential bonding mustbe guaranteed. We recommend the use of the following modules to protect the data transmission lines:•• Surge arrester SA 1000, SA 5000, SAC055 orBlitzductor® XT Types BXT ML2 BE S 5 or BXT ML4 BE 5,by Dehn or equivalent product•• M-Bus: Blitzductor® XT Types BXT ML2 BDS 48 or
BXT ML4 BD 48, by Dehn or equivalent product•• 230 V network: DEHNguard® S Type DGT 275 by Dehnor equivalent product
TV-SK 6364 contains additional information.
Installing bus line and shielding
Make sure the bus lines are installed correctly to avoid any
possible disturbances.
•• Properly shield the bus cable (shielding must be used on
both sides and cover a large area)•• Connect the bus devices over the shortest distance•• Reduce different potentials by using sufficient equipotential
bonding, otherwise transient currents can be conducted
over the shielding!
