1 Safety
1.1 Safety instructions
Read this chapter and the entire instruction manual carefully and follow all instructions
listed. This is your assurance for dependable operations and a long life of the device.
Keep this instruction manual in a safe place to have it handy every time you need it.
1.2 Symbols and Signal Words used in this Instruction Manual
Danger!
Please observe this safety message to avoid electrical shock!
There is danger to life!
Warning!
Please observe this safety message to avoid bodily harm and injuries!
Caution!
Please observe this safety message to avoid damages to property and devices!
Notice!
Additional information for the use of the device.
1.3 Intended use
The Multi Signal Converter is a device, which can be used to convert and distribute
DCF signals.
However, it can also be used for other types of signals. The limitation is given by the
frequency of the signals and the signal form. Ideally, the device is used for digital sig-
nals. See also chapter 7 Technical data.
Please refer to section - 3.3 Function description - for a detailed function description.

1.4 Observe operating safety!
•Never open the housing of the device! This could cause an electric short or even a
fire, which would damage your device. Do not modify your device!
•The device is not intended for use by persons (including children) with limited physi-
cal, sensory, or mental capacities or a lack of experience and/or knowledge.
•Keep packaging such as plastic films away from children. There is the risk of suffo-
cation if misused.
1.5 Consider the installation site!
•To avoid any operating problems, keep the device away from moisture and avoid
dust, heat, and direct sunlight. Do not use the device outdoors.
•The Multi Signal Converter is designed for DIN rails and should only be operated
installed on a DIN rail.
Danger! Make sure
that you wait before using the device after any transport until the device has
reached the ambient air temperature. Great fluctuations in temperature or humid-
ity may lead to moisture within the device caused by condensation, which can
cause a short.
1.6 Observe electromagnetic compatibility!
The device complies with the requirements of EMC directive 2004/108/EC and
96/48/EC

2 Maintenance
2.1 Troubleshooting: Repairs
If you cannot rectify the problems, contact your supplier from whom you have pur-
chased the device.
Any repairs must be carried out at the manufacturer’s plant.
Disconnect the power supply immediately and contact your supplier, if …
•liquid has entered your device
•the device does not properly work and you cannot rectify this problem yourself.
2.2 Cleaning
•Please make sure that the device remains clean especially in the area of the con-
nections, the control elements, and the display elements.
•Clean your device with a damp cloth only.
•Do not use solvents, caustic, or gaseous cleaning substances.
2.3 Disposing
Device
At the end of its life cycle, do not dispose of your device in the regular household rub-
bish. Return your device to your supplier who will dispose of it correctly.
Packaging
Your device is packaged to protect it from damages during transport.
Packaging is made of materials that can be disposed of in an environmentally friendly
manner and properly recycled.

4 Configuration, Displays and Connections

DC IN
Power input, nom. 24VDC / < 100mA (12V-60V)
Remark: Correct +/- polarity required. Internal thermical fuse

DC OUT
Directly wired to DC IN. Used for power cascading to next converter.

SUP ANT
Power output for power supply of the GPS/GNSS receiver.
Same voltage as DC IN but limited to 30VDC.

DCF ANT
DCF input, active current loop input. For the connection of a GNSS receiver
(with DCF current loop out) or any other DCF source.
30V / 30mA, current limited, min signal level: approx. 6 mA

SIG IN
Voltage signal input 2-24V, potential against GND, inverted (-) resp. none-
inverted (+),or differential connection (RS422)
Ref.: Out 2.5VDC, used to define the unused input (+ or -)

DCF OUT
4 galvanically separated outputs for current or voltage interfaces:
- Passive current loop interface 12mA max. 30V
- "Open Collector" application 3-30V

TTL OUT
Signal output 5V, transparent resp. inverted or as RS422 output
Signal cascading to next "Multi Signal Converter"

FO IN / OUT
Option: Fiber optic in- and output 1Hz - 10MHz (820nm / ST Port)

SIG INV
Inversion of the output signals "DCF OUT" and "FO OUT"
Jumper position: "OUT" = Signal transparent, "OUT" = Signal invertiert

LED‘s
green: power supply yellow: signal activity (DCF, SIG IN, FO IN).
Flashes to the beat of input signal or with approx. 20Hz at higher frequency

Important !
The signal inputs are "OR" con-
nected.
This means, only one input must
be used.
Signal-Inversion
The “Multi Signal Converter”
works in transparent mode by
default, i.e. the signal polarity at
the output is the same as at the
input.
The jumper for signal inversion
should only be repositioned in
special cases.
The inversion only takes place
for "DCF OUT" and "FO OUT".
The output "TTL OUT" is not af-
fected since the signal is already
available in inverted form (-).
