Manual ISM–usb.1 / .2
1. Introduction
1.1 General information
The IBRit-rf1 and ISM radio module series allow the wireless transmission of measurement data
from gauges to a PC with USB - interface or to an IMB-rf1 / IMB-ISM module ( as the case may be ).
On the PC side the wireless communication with the gauges occurs via the ISM-usb
PC - Radio station.
The ISM-usb PC - Radio station is connected to the PC via an USB - port and allows the communication in
an address range from 1 ... 500.
The differentiation of the data from the individual radio modules is achieved by address numbers. The
address number and other individual radio module settings concerning the particular application can be
transmitted from the PC to the radio modules and are stored there.
The corresponding PC software IBR_SimKey is included in the delivery of the ISM-usb PC - Radio station.
The transmission of measurement data is triggered by pressing the data key on the gauge ( if available ), or
on the radio module or automatically when the measuring value changes. The radio module completes the
measured value by adding an address number ( sender ), a communication control word and a double
checksum. The special data coding and the PC’s reply directly to the radio module guarantee absolute data
security.
A transmission error, e.g. caused by a radio interference, is detected by the communication dialogue
between PC and radio module. The measurement data transmission is automatically repeated up to 3
times within 0,01 ... 0,08 seconds. A successful measurement data transmission is confirmed to the user by
a green flashing light and short beep tone on the radio module. If the PC could not receive the measure-
ment data from the radio module faultlessly, a red flashing LED and two long beep tones inform the user
about the faulty measurement data transmission. The user can obtain further error information by reading
the red LED’s Morse - code ( please refer to page 14 of this manual ).
The maximum radio range depends strongly on the environment and can vary from several meters up to
300 meters.
The received measurement data can be made available for nearly any software, because the IBR_SimKey
PC software utilizes the keyboard buffer to output the measurement data.

When the selections concerning the PC - connection and the IBR - instrument have been made, the
columns Connection and Gauge / Sensor are filled and displayed as shown below.
Note : If a (*) appears behind the entry IBR-ISM, then the ISM module was not found
( e.g. no driver installed, the IBR-ISM is used by another software, … ).
The gauge radio modules can be individually either activated or deactivated for operation with a
particular PC - Radio station. In order to do so, please click the on ( off ) - button of the radio module
concerned. The button is located directly on the right - hand side of the Gauge / Sensor column.
This programming possibility allows simultaneous operation of several PC - Radio stations with up to
120 radio modules. The addresses 121…499 can be assigned via the Setup buttons of the respective
channels.

Manual ISM–usb.1 / .2
In the upper left - hand area of the programming window you can find the selection column containing the
commands available for programming. The selection column containing the appropriate parameters is
located directly to the right of it.
For programming please select the command to be executed and then the desired parameter. By clicking the
OK - Button the chosen command is loaded into the transmission buffer. Now, please press the data key of
the radio module which is to be programmed, in order to trigger measurement data transmission. On the end
of the measurement data transmission the PC - Radio station sends the chosen command from the
transmission buffer to the gauge radio module. The radio module confirms successful programming by a short
tone sequence and a triple flash of the green LED.
