2 Area of application
The receiver module was designed to receive radio
frequency signals from energy harvesting switches
(AFIM / AFIS). The receiver is suitable for wall or rail
installation in the area of automation technology and
has different connection options.
3 Interfaces
3.1 Power supply interface to connect the
power using the external supply
Use the „Power supply“ interface to connect the
power using an external supply. The external supply
must be galvanically isolated. The input voltage may
total 7 to 24 V DC.
1 Observe the polarity (left + right – when viewed
from the front)
2 Connect the external supply using the spring
terminal (wire diameter 0.5 to 1.5 mm2). To do
so, press the spring downwards by inserting a
screwdriver into the smaller opening, and by
pushing the wire into the larger opening.
3.2 USB service interface
The USB interface is used for communicating with a
PC and for connecting power using a USB Micro-B
plug. The interface can be used for evaluating data
received wirelessly for service purposes. The interface
is protected from short circuits by a 500 mA SMD
fuse. Observe the maximum values for the USB
interface standard.
If the receiver is already connected to the power
supply interface when the USB is connected, then a
reset must be carried out in order for USB
communication to function.
3.2.1 USB transmission parameters
The USB connection appears as a virtual COM port in
the PC. You can configure it on the PC any way you
like.
If a transmitter has not been paired, then information
from all transmitters will be output (see 3.4.3 „TTL
data format“). If at least one transmitter has been
paired, then only the paired transmitters will be
output.

4 Starting up
4.1 Mounting the antenna sleeve
The receiver has a fitted wired antenna. You need to
mount the antenna sleeve for protection and a
straight alignment.
1 Guide the wire antenna into the opening at the side
of the antenna sleeve
2 Insert the antenna sleeve into the holder
horizontally and turn it 90 degrees to the left.
The antenna sleeve is mounted.
4.2 Connecting the power supply
The power is supplied using an external supply (see
3.1 “Power supply interface to connect the power
using the external supply”) or a USB Micro-B plug
(see 3.2 “USB service interface”).
5 Pairing a transmitter
You can pair the transmitter either with the standard
setting (see 5.1 "Simple transmitter pairing") or with a
function (see 5.2 "Pairing transmitters with
functions").
You can pair up to 32 transmitters. In addition, during
pairing, you can decide which function the receiver
should output upon signal reception.
Note that every transmitter only performs with one
function.
V02 EN Okt 2016 (BA_Empfaenger_EN_V02) ZF Friedrichshafen AG 3
On the receiver there are two buttons with LEDs on
the left at the top in a recess. Press the buttons with
a sharp object such as a ball-point pen.
1 Get the transmitter that you want to pair ready.
If you do not touch anything more for than 2
minutes during the procedure, it stops
automatically.
2 Connect the receiver to the power supply.
The left LED flashes green (if a transmitter has not
yet been paired) or lights up green (if a transmitter
has already been paired).
5.1 Simple transmitter pairing
Simple transmitter pairing is used to save the
“button” function (see 5.2 "Pairing transmitters with
functions", function number 1). This means that the
output signal switches between active and inactive
every time the wireless switch is pressed.
CAUTION: Unintentional transmitter
pairing
• Do not allow transmitters to be triggered that
are not supposed to be paired during the
pairing procedure.
1 Press the right button for 2 seconds (Pairing) until
the right LED flashes yellow.
2 Trigger a signal on the transmitter.
3 If applicable, trigger a signal on the other
transmitters you wish to pair.
You can pair up to 32 transmitters consecutively.
4 Press the right button briefly (Pairing).
The left LED lights up green and the right LED is off.
The transmitters are paired.
5 Trigger a signal on the transmitters you have just
paired to check them.
The right LED flashes in yellow with every signal,
and you can hear the relay switch on the receiver.
5.2 Pairing transmitters with functions
You have to pair each transmitter separately.
You can allocate the following functions to the signal
received when pairing:
Function
number
Signal output on
the receiver

1 Press and hold the right button (pairing button).
2 At the same time, briefly press the left button (reset
button) whilst continuing to hold down the right
button until the pairing LED flashes yellow.
The reset LED should now be solid green and the
pairing LED should be flashing as per for “function
number 1” sequence (see table below).
3 If required, the function can be changed by
pressing the pairing button, as described in the
table. This must be done at intervals of less than 1
second. For example: Function 2 requires two very
brief actuations of the pairing button.
The receiver will recognize this command after
approx. 1 second. The pairing LED will then flash
yellow, in accordance with the function number.
4 Trigger a signal on the transmitter.
Both LEDs should now show a solid light.
CAUTION: If only the reset (left) LED is flashing
green, then another transmitter was triggered in error
during this process. This causes a collision, as the
receiver is not able to determine which transmitter
should be paired. In this instance:
• Press the pairing (right) button for 2 seconds.
• Trigger the required transmitter again.
5 Press the pairing button briefly.
The pairing LED will then flash yellow according to
the selected function. For example: Twice per
second for function 2.
6 Press the reset button briefly.
The reset LED will then, following a brief pause,
display a solid green light and disconnect the
pairing LED. The transmitter is now paired.
7 Trigger a signal on the transmitter to varify pairing.
The pairing LED then flashes yellow with every
signal, and the relay switch can be heard on the
receiver.
6 Deleting transmitters
You can delete individual transmitters, or all
transmitters.
Connect the transmitter to the power supply.
The left LED lights up in green (if at least one
transmitter has been paired).
If you do not touch anything more for than 2 minutes
during the delete process, the procedure is canceled
automatically.
6.1 Deleting individual transmitters
1 Have the transmitter that you want to delete ready.
2 Press the right button for 4 seconds (Pairing) until
the right LED starts by slowly flashing before
flashing rapidly.
3 Trigger a signal on the transmitter you wish to
delete.
If only the left LED is flashing green, then another
transmitter was triggered in this phase. This causes a
collision, as it is not possible to distinguish which
transmitter is supposed to be deleted. In this case:
• Press the right button (Pairing) for 2 seconds.
• Trigger the required transmitter again.
The right LED lights up in yellow.
4 Press the right button (Pairing) as confirmation.
The right LED flashes yellow rapidly.
5 Briefly press the left button (Reset).
The transmitter is deleted. If only one transmitter
was paired, the left LED flashes green. If at least
one more transmitter was paired, the left LED lights
up in green.
6 Trigger a signal on the transmitters you have just
deleted to check them.
If it was deleted, nothing happens. If it was not
deleted, right LED flashes yellow with every signal,
and you can hear the relay switch on the receiver.
In this case, repeat the delete procedure.
6.2 Deleting all transmitters (Reset)
1 Press the right button (Pairing) and hold it down.
2 Press the left button briefly (Reset) while also
holding down the right button (Pairing).
3 When the right LED starts flashing slowly and then
flashes faster after 4 seconds, release the right
button (Pairing).
The left LED flashes green. All transmitters are
deleted.
7 Error messages
If an error occurs, the left LED (Reset) flashes green
rapidly. The right, yellow LED shows the error code. If
several errors occur, then the error with the highest
priority (error number) is shown.
