1Introduction
The wireless HW 8612 Radio Device is the ideal solution when re-
placing V.24 cables by a radio connection or when addressing dif-
ferent peripheral devices via common interface.
The HW 8612 has a transmission rate of 115kbit/s and is provided
with an automatic error correction function; thus data transmission
is as reliable as with a common cable connection.
This manual describes the technical details of the HW 8612 as well
as its hard- and software. Furthermore, it explains how to take it into
operation and how it is currently used.
In case of problems during the installation or during the operation of
the HW 8612 that cannot be solved with the information given in
this manual, please contact the service department of your local
dealer or contact the Höft &Wessel-service line directly under

1.1 Attendance and maintenance
The HW 8612 does not require maintenance work or special atten-
dance, except for the instructions mentioned below.
♦Do not operate device within the range of strong electromag-
netic fields.
♦Notice the temperature range for operation given in chapter 5
Do especially avoid overheating.
♦Protect device against humidity and dust.
♦Do clean device only with a soft wet cloth and mild cleaning
agent.
♦Do not insert objects which do not correspond to the correct
application purpose into openings of the device. (This could
destroy electronic components).
NOTE!
Do not open the HW 8612
The HW 8612 does not contain parts which can be maintained,
exchanged or repaired by the customer or non-authorised
maintenance personnel.
Opening the device might damage the electric components. A
correct function of the device is no longer guaranteed!

1.2 Special note
NOTE:
This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. However, there is no
guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following
measures:
♦Reorient or relocate the receiving antenna.
♦Increase the separation between the equipment and
receiver.
♦Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
♦Consult the dealer or an experienced radio/TV technician for
help.
The maximum output power of the Base Station transmitter is
100 mW. Though this is a low power level a minimum
separation distance of 20 cm from the enclosure of the Base
Station to all persons must be kept. The antennas must not be
co-located and operating in conjunction with any other
antenna or transmitter.

2.3 Ports
2.4 LEDs
LED2 is pulsating when the power supply is connected.
The LED switches to continuous green if the serial interface COM-
MOD of the HW 8612 recognises a corresponding counter part
(modem or comparable peripheral device) with opened port (DSR
has been set). It flickers if data is sent.
If you press the push button for about 3 seconds LED1 and LED2
will flash in turns. The HW 8612 is now ready for subscription.

3Application example
3.1 Using the HW 8612 as modem cable replacement
This application requires two HW 8612. One is connected to the
RS-232 interface of a PC, the other is connected to a commercial
modem connected to your phone connection box.
This structure allows for an internet access of your PC without con-
necting the PC directly to the phone connection box. The actual
connection is established between the two HW 8612. Long cables
are no longer necessary.
3.1.1 Hardware installation
Step 1:
Connect one serial cable to the serial interface COM-PC of the HW
8612 and the other end of the cable to the serial interface of your
PC. Connect the power supply unit to the DC-socket of the HW
8612 and connect the plug of the power supply unit to the mains.
Step 2:
Connect one serial cable to the serial interface COM-MOD of the
HW 8612 and the other end to the serial interface of your modem.
Connect the power supply unit to the DC-socket of the HW 8612
and connect the plug of the power supply unit to the mains.

4.2 Configuration software
To establish a wireless communication between two HW 8612
setup a base and a mobile station.
The included software guides you through the required configura-
tion process.
4.2.1 Step 1: Welcome
Click button [OK]
4.2.2 Step 2: Connect base station
Connect one HW 8612. Select the COM port the HW 8612 is con-
nected to. Click button [OK]. If the connected HW 8612 is config-
ured as mobile station the software will configure it as base station.
