Description
The RAD-ISM-2400-SET-BD-BUS-ANT bidirectional
wireless system comprises two transceiver devices. The
transceivers can transmit and receive wireless signals. The
transmit/receive function is managed automatically.
The bidirectional system can be extended by mounting
additional modules via the bus foot on the side. This enables
additional digital and analog signals to be acquired and
transmitted.
Each transceiver accommodates two digital signals
(5 V AC/DC ... 30 V AC/DC) and one analog current signal
(4 mA ... 20 mA). The signals are available at the outputs
(two N/O relay contacts and one analog current output) of
the other transceiver. An RF link relay diagnoses the
existing wireless connection. A power LED indicates
whether the power supply is present. The status LED
indicates whether the station structure on the relevant
partner is correct.
The RAD-ISM-2400-REP-SET-BD-BUS repeater system,
which otherwise has the same structure, comprises three
transceiver devices. It is used to overcome large obstacles
or to increase the range.
Make sure you always use the latest documentation.

RF link relay
The RF link relay in the transceiver diagnoses the
status of the wireless connection. It picks up when
the wireless connection is established. If no data
packets are received correctly over a period of
approximately 5 seconds, the relay drops again. It
picks up again automatically when the wireless
connection is re-established. The RF link relay has
been designed as an N/O contact.
LED: Power
ON = Operating voltage UB present
LED: RF-Link
OFF = Operating voltage UB not present
Flashes briefly approximately every 2 seconds = No
reception
Flashes quickly = Weak connection

LED: Digital OUT 1 + OUT 2 = Status of the digital

RSSI test socket
A voltage measuring device (handheld multimeter)
can be connected to the RSSI test socket to measure
a voltage, which provides information about the
received wireless signal. Using the diagram shown in
Figure 3, the received signal strength in dB can be
determined using the voltage value. This can be
useful when positioning and aligning the antenna,
for example.

The 4 mA ... 20 mA analog input 2 detects active and
passive current sensors (see "Connection examples" on
page 9).
7.3
Digital inputs
Both digital inputs 3 of the transmitter can process voltages
from 5 V AC/DC ... 30 V AC/DC. They are electrically
isolated from the operating voltage UB.
7.4
Analog output
The analog output 2 has been designed as a passive
output. The internal power supply can be used to supply the
actuator.
The output requires an internal drop voltage of 10 V.
The maximum load at the current output with a nominal
voltage of 24 V = (24 V - 10 V)/20 mA = 700 Ω. The
maximum load therefore depends on the operating voltage
UB used.
7.5
Digital outputs
Two floating N/O contacts are used as the digital outputs 3
for the transceiver.
8
Behavior in the event of the
wireless connection being
interrupted
If the wireless connection is interrupted, all outputs (analog
and digital) retain their last value or status (see connection
examples).
To configure a reset response (revert back to "0") for a
digital signal or the analog signal when a wireless
connection is interrupted, connect the RF link relay contact
in series, for example.
To configure a reset response for all signals, use the RF link
relay to control one or more additional relays.

Avoiding ground loops
NOTE: Device damage caused by compensating currents
Differential voltages may occur between the potentials when the ground connections are physically separated.
These voltages may cause compensating currents over the low-resistance path marked in red. Just a few volts can
cause compensating currents in the range of several amperes, which may damage the device.
Figure 9 shows the course of the compensating currents, which is created when different supply voltage sources are used
for the sensor and the RAD-ISM-... device, and when the two sources have a separate ground reference. This arrangement
(using different sources for sensor and RAD-ISM-... system) does not always cause problems. However, high compensating
currents (in the range of several amperes) may cause damage to the device. To avoid these effects, the complete
arrangement must only be grounded at one central point (e.g., not using the connection to PE2).

Installation in the Ex area
With certification according to Directive 94/9/EC (ATEX) and IECEx, the RAD-ISM-2400-SET-BD-BUS-ANT bidirectional
wireless system is a category 3G, "n" protection type component, and can be used internationally in the Ex area of zone 2
with hazardous gases. Signals from outside the Ex area as well as signals from zone 2 can be connected directly. Signals
from zones 1 and 0 cannot be connected directly. They can only be connected via the appropriate barriers because the
inputs are not intrinsically safe.
Due to the limited transmission power the wireless path itself may be led through zone 1 and zone 0. There are no restrictions
here.

Repeater
Repeaters can be used to overcome large obstacles
(e.g., mountain tops) or to increase the range.
Repeaters are simple transceivers with a special HOPKEY.
To extend an existing point-to-point system with a repeater,
an additional transceiver (RAD-ISM-2400-BD-BUS,
Order No. 2867746) and a HOPKEY with repeater
configuration are required for the existing set.

Important: Bidirectional data exchange is also
possible with extension modules in a point-topoint connection with a repeater.
Signals cannot be detected or output at the
repeater. The cycle time when transmitting in one
direction doubles from 37 ms to 74 ms.

HOPKEY replacement
The HOPKEY must be replaced when replacing faulty
transceivers or when extending a system to create multireceiver or repeater systems.
The HOPKEY contains information such as the
transmission frequencies used and the hop sequence. This
information is required when installing an additional
receiver/repeater in an existing system.
OMNEX
HOP KEY
To install a HOPKEY, proceed as follows:
1. To protect the modules against ESD, the operating
personnel must remove electrostatic discharge at
appropriate points (e.g., control cabinet) before
touching the modules.
2. The existing system must have established a wireless
connection.
3. Disconnect the power to the existing system.
4. Open the housing of the transceiver in the existing
system by pressing both housing latches on the sides.
Remove the electronics module from the housing (see
Figure 17).
5. At the bottom right on the PCB is a small PCB in a
10-pos. base – this is the HOPKEY. Remove the
HOPKEY and insert it in the same position in the new
transceiver that you wish to install (see Figure 18).
6. Close all the housing covers and reinsert the modules in
the control cabinet(s).
7. Reconnect the supply voltage – the new transceiver
now also operates in the existing system.
8. Repeat the procedure for all additional receivers/
repeaters.
102113A008
Explanation:
When the supply voltage is connected, the information is
transmitted from the connected HOPKEY to a non-volatile
memory inside the module. This HOPKEY can then be used
to "teach" other receivers. The HOPKEY can be stored in
the last receiver.

Removing the electronics module
If no HOPKEY is connected, the information inside the
module is used.

HOPKEY replacement applications
Replacing a faulty transceiver in a point-to-point
system
If a faulty transceiver has to be replaced, only one
replacement module (RAD-ISM-2400-BD-BUS,
Order No. 2867746) is required.
• Remove the HOPKEY from the faulty module (see
page 18) and insert it in the replacement device. The
system continues to operate after switching on the
supply voltage.
If a HOPKEY is ever lost in a point-to-point system, an
appropriate replacement can be ordered as follows. Check
whether "M" or "S" is specified next to the identification
number (ID) on the HOPKEY. In a point-to-point system,
one HOPKEY with "IDxxxxxM" and one HOPKEY with
"IDxxxxxS" must always be available. Order as follows:

The point-to-multipoint system is ready to operate once all
the modules have been switched on at least once with the
HOPKEY.
Repeater function in the point-to-point system
If an existing point-to-point system is to be extended by one
or more repeaters, at least one transceiver
(Order No. 2867746) is required for your
RAD-ISM-2400-SET-BD-BUS-ANT, as well as the following

The HOPKEY is installed in the additional transceiver (see
page 18). If additional repeaters are used, the HOPKEY is
replaced by the additional transceivers one after the other.
Expansion to create a point-to-multipoint system
When extending a point-to-point system to create a point-tomultipoint system, two new HOPKEYs are required for your
system in addition to the desired number of additional
transceivers (Order No. 2867746). This HOPKEY pair can
be used to assign transmitter (point) and receiver
(multipoint) functions to the transceiver devices.
To do this, the following HOPKEYs must also be ordered
(one PMM and one PMS):

In the point-to-multi-point application, the "PMM" HOPKEY
is used in the transceiver that is used for transmission
(point).
• Install the HOPKEY according to page 18.
The "PMS" HOPKEY is installed in the transceivers one
after the other on the multipoint side. This means that these
transceivers are used as receiver modules for the
transmitter.

Tips and notes

10.1
Notes on the general assignment of
frequencies
–
–
In Gazette 22/1999, Order 154, the German regulating body
for telecommunications and mail (RegTP) stipulated a
general assignment of frequencies.
Appendix
EC declaration of conformity (see page 21)
Declaration of conformity with health requirements
(see page 23)
This general assignment applies to wireless systems in the
frequency range from 2.400 GHz ... 2.4835 GHz for general
use.
Section 10 specifies that the wireless system operator has a
duty to notify the RegTP in writing of the installation of a
system, if it uses transmission paths that extend
beyond the site.
If, for example, another wireless system that adversely
affects an existing RAD-ISM system is installed, then this
system must adjust its operation if the existing system has
already been registered with the RegTP. System
registration is therefore designed to protect the system
operator.
10.2
Notes on operating other wireless systems in
close proximity
If other wireless transmission systems are operated on the
same frequency band close to an INTERFACE wireless
system, interference may occur.
The effects on the RAD-ISM-2400-SET-BD-BUS-ANT are
marginal and barely noticeable.
However, in certain circumstances an installed WLAN
system (IEEE 802.11b) may be disturbed by frequency
hopping, even if all specified maximum values are
observed.
To provide a solution for these cases, the
RAD-ISM-2400-SET-BD-BUS-ANT reserves a small
frequency range in the 2.4 GHz band.
This is the range from 2.4220 GHz ... 2.4420 GHz, which
corresponds to channel 5 of a WLAN system according to
IEEE 802.11b.
Should you experience the problem described above,
please configure your WLAN system to channel 5.
