1 Application
The TROVIS 5482 Repeater is used in a
RS-485 bus system to increase the line length
by 1200 m.
CAUTION!
Assembly, start-up and operation of the device may only be performed by trained and
experienced personnel familiar with this product.
It can also be used to convert data for a
4-wire bus system into data for a 2-wire bus
system.

2 Principle of operation
Principle of operation
The device is equipped with two interfaces,
X1 and X2, which are electrically isolated
from each other as well as from the PE
connection.
Four LEDs are located on the front side of the
device. When they are illuminated or blink,
the following conditions are signalled:
Power on
X1 sending data
X1 receiving data
X2 recognizes that transmitter is active
(DCD)
There is a series of jumpers on the printed
circuit board inside the device which allows
the repeater to be adapted to the requirements of a RS-485 bus system. Fig. 1 illustrates the position of the jumpers. The casing
can be opened as described in section 3. The
following functions can be selected or set (for
the exact jumper settings and the default positions refer to Tables 1 to 6):
Selecting a 2-wire or 4-wire system
Depending on the bus system used, a 2-wire
or 4-wire system must be selected for each
interface (see Table 1).
Controlling the transmitter for interface X2
A signal level detector is located at both in
terfaces. It recognizes whenever a bus station
sends data (transmitter activated). In the
2-wire system, it controls the switching bet
ween sending and receiving data. The signal
level detector can be disabled. In that case,
sending and receiving are switched over by
the data itself (see Table 3). An adjustment of
the transmission rate is not necessary.
Blocking duration of the transmitter
In the 2-wire system, one interface is blocked
whenever the other interface sends data.
Jumpers X16 and X17 allow the duration of
the blocking to be changed, should communication problems occur (see Table 4).
Increasing the duration of the transmitters
switching signal for X2
In order to prevent reflections in the lines of
the 2-wire system, the transmitters switching
signal can be lengthened.This is only possi
ble for the interface X2 (see Table 5).

-
Bus termination of interfaces
The bus can be terminated both at interface
X1 and at X2 by positioning the jumpers X6,
X7 and X11, X12 as shown in Table 2.
Grounding the interfaces
If necessary for older devices, it is possible to
ground the interfaces X1 or X2 by changing
the position of the jumper X5 as described in
Table 6.

3 Opening the device
CAUTION!
Do not open the device, unless the power is turned off. The device may only be opened
by experienced personnel!
When changing the jumper positions accor
ding to the instructions in section 2, proceed
as follows:
1. Disconnect mains plug, if necessary.
2. Loosen the two screws located on the bot
tom of the case.
3. Separate the two case parts, taking care
that the front panel does not fall out.

4 Electrical connections
The power supply connection 230 V as well
as both terminals for the interfaces X1 and
X2 are located on the rear panel as shown in
Fig. 2.
Connect the data lines for interfaces X1 and
X2 to the supplied 5-pin connectors using
screw terminals. For the data lines, we recommend using a twisted pair of wires,
non-screened cable with a cross-section of
2
0.5 mm
100 nF/km and a line resistance of
maximum 100 Ω/km. Use a shielded cable
if the electrical interference is strong. The
shielding must only be connected at one end
to prevent ground currents. It must be noted

that the transmission properties are reduced
with increased cable capacitance and smaller cable cross-sections which leads to a reduction in the bus range.
For the assignment of the data line connections, depending on the type of line selected,
refer to Tables 7 and 8. Fig. 3 shows the typical wiring in a 4-wire system.
Use the power supply cable supplied for the
power supply connection 230 V.
