INTERFACE
Wireless communication is based on Trusted Wireless 2.0
technology. The high demand for a interference-free data
transmission using the license-free 900 MHz band, in partic-
ular via the use of the FHSS method (FHSS) and 128-bit
data encryption (AES), is fulfilled.
In addition to an RS-232 and RS-485 2-wire interface, the
RAD-900-IFS wireless module supports the option of di-
rectly connecting up to 32 I/O extension modules in the sta-
tion structure via the TBUS DIN rail connector.
Addressing of the wireless module and I/O mapping of the I/
O extension modules is carried out quickly and easily by
means of the thumbwheel on the front. Programming knowl-
edge is not required.
The PSI-CONF configuration and diagnostics software for
special functionality and diagnostic options in the wireless
module is available free of charge.
Features
– Flexible network applications: I/O data, serial data,
PLC/Modbus RTU mode
– Adjustable data rates for the wireless interface
– Easy point-to-point or network structures (star, repeat-
er)
– Quick and easy startup thanks to simple wireless mod-
ule addressing using the thumbwheel on the front
– Integrated RS-232 and RS-485 interface
– Can be extended with up to 32 I/O modules per station
via T-BUS (hot-swappable)
– 128-bit data encryption (AES)
– Unique network addressing via plug-in configuration
memory (RAD-CONF) for secure, parallel operation of
multiple networks (different RF bands)
– Data rates and ranges can be adjusted

5 Safety regulations and installation
notes
5.1 Installation notes
The use of antennas with a gain greater than 6dBi may re-
quire that the transmit power be reduced from the default
setting of 30 dBm. Regulations limit the equivalent isotropi-
cally-radiated power (EIRP) to 36dBm. The EIRP may be
calculated as the transmit power (Pt) minus any cable loss
(Lc) plus the antenna gain (Ga).
For example, in the case of a 12dBi antenna used with a
cable run with a 4dB loss, the transmit power must be re-
duced to 28dBm or less such that the EIRP does not exceed
36dBm.
5.2 Installation and operation

- Changing the I/O MAP address of the extension modules
- Adding an I/O extension module
- Removing an I/O extension module
- Using the CONF/memory stick
– Changing the RAD ID address of the wireless module.
– Changing the I/O MAP address of the extension mod-
ules.
– Adding an I/O extension module.
– Removing an I/O extension module.
– Using the CONF/memory stick.
RSSI LED bar graph
In a point-to-point connection, the LED bar graph is active on
the master and on the repeater/slave. The same signal
strength is displayed on both modules.
In a wireless network with more than one repeater/slave,
only the yellow LED on the master is permanently on. The
signal strength is displayed on the repeaters/slaves. The
signal strength is always related to the wireless module
which is directly connected.

RF link relay
The RF link relay in the transceiver diagnoses the state of
the wireless connection. It picks up when the wireless con-
nection is established. If no data packets are received cor-
rectly over a period of 10s seconds, the relay drops out
again.
It picks up again automatically when the wireless connection
is re-established.
The RF link relay has been designed as a PDT contact.
RSSI test socket
A voltage measuring device can be connected to the RSSI
test socket to measure a voltage, which provides informa-
tion about the received wireless signal. Using the table
shown below the LED bar graph, the received signal
strength can be determined using the voltage value. This
can be useful when positioning and aligning the antenna, for
example.
6.4 Assembly/removal
Connection station with I/O extension modules
Up to 32 different I/O extension modules can be connected
to each RAD-900-IFS wireless module via the TBUS DIN rail
connector (see accessories). Data is transmitted and power
is supplied to the I/O extension modules via the bus foot.
Figure 4 Radioline connection station with up to 32 I/O
extension modules
DIN rail mounting
Figure 5 Mounting and removal
1. Place the device onto the DIN rail from above so that the
upper housing keyway hooks onto the top edge of the
DIN rail.
2. Rotate the device toward the DIN rail so the device bus
connector is securely mated with the TBUS connector.
3. Once the foot snaps onto the DIN rail, check that it is
fixed securely.
The RF link relay can be used as a fault mes-
sage contact to indicate the failure of the wire-
less connection to the controller.
When the wireless module power supply is
19.2 - 30.5VDC, up to 32 different I/O exten-
sion modules can be connected. When the
power supply is 10.8 - 17.0VDC, up to four I/
O extension modules can be connected.
The I/O extension modules must only be
mounted to the right of the wireless module.
When using the RAD-900-IFS in a connection
station, use the supplied 17.5mm wide DIN
rail connectors.
Make sure that the DIN rail connector and de-
vice are aligned correctly.

6.6 Serial pin assignment
Connect the I/O device to the RAD-900-IFS wireless module
via the necessary serial interface.
Shielding
Connect the shield of the RS-485 bus cable correctly via an
external shield connection clamp.
Choose the type of shield connection according to the type
of interference expected:
– Connect the shield on one side to suppress electrical
fields.
– To suppress disturbances caused by alternating mag-
netic fields, connect the shield on both sides. When do-
ing so, the ground loops must be taken into account:
galvanic disturbances along the reference potential can
interfere with the useful signal, and the shielding effect
is reduced.
– If several devices are connected to a single bus, the
shield must be connected to each device (e.g.,by
means of clamps).
– Connect the bus shield to a central PE point using short,
low-impedance connections with a large surface area
(e.g.,by means of shield connection clamps).
Activating/deactivating the termination network
The RAD-900-IFS wireless module is operated on a 2-wire
bus cable. For correct operation of the bus system, termina-
tion networks are required for the RS-485 bus connection.
The RS-485 cable must be terminated at both ends of the
bus with a 390/150/390Ω termination network. Depending
on the position of the device on the RS-485 cable, this can
be implemented as shown in the table below.
Operating mode of the wireless module
The operating mode of the device is set using a termination
network depending on the location on the RS-485 bus cable.
Select the required operating mode and set it using the DIP
switch.
Parallel operation of the interfaces is not pos-
sible.

RS-485 pin assignment
In RS-485 mode, an RS-485 network with several I/O de-
vices can be created. Use a twisted pair bus cable to con-
nect the I/O devices. Fit this bus cable with a termination net-
work at the two furthest points of the RS-485 network.
Connect the individual conductors of the data cable to the
COMBICON plug-in screw terminal block.
In RS-232 mode, point-to-point connections can be estab-
lished.

7 Startup and configuration
All RAD-900-IFS wireless modules have the same default
configuration.
Default settings
Operating mode: I/O data mode (wire in/wire out)
Wireless interface
For simple I/O data applications (wire in/wire out), address-
ing is carried out easily using a thumbwheel. You can there-
fore establish a wireless connection to other RAD-900-IFS
devices without any programming effort.
For serial data transmission, PLC/Modbus RTU mode or
changes to the “default settings”, each wireless module
must be configured using the PSI-CONF configuration and
diagnostics software. See Section 7.8, “PSI-CONF configu-
ration and diagnostics software”.
7.1 Resetting to the default settings
1. Disconnect the device from the supply voltage.
2. Press the "SET" button on the front of the device.
3. Switch the supply voltage back on.
4. Press and hold the "SET" button until the "DAT" LED
flashes.
Alternatively, you can reset the device to the default settings
using the PSI-CONF software.
Data communication is only possible using
I/O extension modules.

7.2 Setting the station address (RAD-ID)
The devices in a wireless network are addressed using the
thumbwheel on the front of the RAD-900-IFS wireless mod-
ule.
Set the desired station address with the yellow thumbwheel
on the wireless module. This results in an initial functional
configuration. There must be one master (address “01”) and
at least one repeater/slave (address “02 to 99”) in a network.
Configuring two wireless modules with the same address
will result in a network that does not function correctly.
The following settings can be made using the thumbwheel:
7.3 I/O data transmission
In order to enable the transmission of signals, you must as-
sign a corresponding output module to the input module.
The following conditions must be met:
Wireless module in I/O data mode (default setting)
Use the white thumbwheel on the I/O extension module to
set the I/O MAP address (01...99).
The input device must be provided with the same I/O MAP
address as the assigned output device at the other wireless
station (I/O mapping).
The I/O MAP address may only appear once in the network.
Exception: outputs with the same address can occur multi-
ple times in different stations on the network.
Figure 13 Example: 2 RAD-DAIO6-IFS with the same ad-
dress
Once the desired number of I/O extension modules have
been connected to the wireless module via the DIN rail con-
nector, the active configuration of the station must be read in
via the "SET" button (item 6 in Figure 1) on the front of the
wireless module.
7.4 Serial data transmission
For serial data communication, you have to activate the “se-
rial data” mode in the PSI-CONF software. Set the interface
parameters of the RS-232 or RS-485 interface such as data
rate, parity, stop bits, and data bits according to the con-
nected application.
Each address in a network must be unique.

** Addressing wireless modules using the
PSI-CONF configuration and diagnos-
tics software (address 1 ... 250)
Setting the address via the thumbwheel has
priority over setting the address via the PSI-
CONF configuration and diagnostics soft-
ware.
After making any change to the module ad-
dress, press the "SET" button for one second
to apply the setting.
After making any change to the I/O MAP ad-
dress (I/O extension module), you must press
the "SET" button on the wireless module to
apply the configuration.
After making any change to the station (e.g.,I/
O MAP address, RAD ID address, adding or
removing an I/O extension module, etc.), you
must press the "SET" button on the wireless
module for 1s to apply the configuration.
Connect a maximum of 32 I/O extension mod-
ules if the power supply is 19.2 - 30.5VDC.

For configuration, you need the RAD-CABLE-USB cable
(Order No. 2903447).
7.5 PLC/Modbus RTU mode
For configuration, you need the RAD-CABLE-USB cable
(Order No. 2903447).
Activate the PLC/Modbus RTU mode in the PSI-CONF soft-
ware.
In PLC/Modbus RTU mode (I/O to serial), you can wirelessly
connect I/O modules directly to a controller. The wireless
module provides an RS-232 or RS-485 interface for this pur-
pose.
In PLC/Modbus mode, the wireless master works as a Mod-
bus slave and has its own Modbus address. The Modbus
address is a unique address, which is only assigned for the
wireless master (RAD-ID=1). You can select an address
1...247.
You can connect I/O extension modules to each wireless
device in the network. A wireless network can have a maxi-
mum of 99 I/O extension modules. Each I/O MAP address
may only appear once in a network.
Use the white thumbwheel on the I/O extension module to
set the I/O MAP address (01...99).
Output modules and input modules must have different I/O
MAP addresses with one exception: output modules with
the same address can occur multiple times in different sta-
tions on the network.
Input and output data is stored in a Modbus Memory Map in
the master wireless module.
The process data tables can be found in the I/O extension
modules' data sheets.
7.6 Behavior of the input and output modules in the
event of an interrupted wireless connection
DIP switches on the I/O extension modules can be used to
set how the analog and digital outputs should behave in the
event of interrupted wireless connection.
"HOLD" DIP switch
If the wireless connection is interrupted, the outputs of the I/
O extension modules retain their last value or state.
"RESET" DIP switch
If the wireless connection is interrupted, the outputs of the I/
O extension modules are reset (output value is set to 0).
7.7 Saving the wireless network
Using a CONFSTICK (see accessories in the "Ordering
data" section on page 3), you can configure a unique and se-
cure network. This enables the parallel operation of multiple
networks (using different RF bands).
The CONFSTICK is inserted in the S-PORT (item 4 in Figure
1) of the RAD-900-IFS wireless module. Once applied, the
information is loaded in an internal memory.

is complete. The new parameters are activated.
4. Remove the CONFSTICK from the RAD-900-IFS.
WARNING: Explosion hazard
Do not insert or remove the CONFSTICK or
memory stick in a potentially explosive atmo-
sphere.
You have to configure each individual network
device. To this end, you only need one
CONFSTICK for all wireless modules in the
network.
After configuration, you can remove the
CONFSTICK from the wireless module.
