Introduction

General Information
The IBRit - rf1 radio module series allows the wireless transmission of measured values from
gauges to a PC with USB - connector.
On the PC side the wireless communication with the gauges occurs via the radio module
IBRit - rf1 - usb
.
The module is connected via a USB-Slot to the PC and allows the communication with 1 ... 120 gauge ra-
dio modules.
The assignment of the data from the different gauges occurs by address numbers. The address number
and other individual radio module settings for the particular gauge type can be transmitted from the PC to
the gauge radio modules and are stored there.
The corresponding PC-Software
IBR_SimKey
is included in the delivery of the
IBRit - rf1 - usb
.
The transmission of a measured value is triggered by pressing the data key on the gauge or radio module.
The gauge radio module completes the measuring value by the address number ( sender ), one
communication control word and a double checksum. The special data coding and the direct
communication between PC and the radio modules on the gauges guarantee absolute data security.
A transmission error, i.e. caused by a radio interference, is detected by the communication protocol
between PC and gauge radio module. The data transmission is automatically repeated within 0,01 ... 0,08
seconds up to 3 times. A successful data transmission is automatically confirmed to the user by a green
flashing light and short beep tone on the gauge radio module. If the measuring value could not be received
by the PC, then a red LED is flashing and two longer beep tones are informing the user about the error.
More information over the different error codes you will find on the page 10.
The maximum transmission distance depends strongly on the environment and can be several meters up
to 200 meters.
The output of the received measurement values can be taken place in nearly every software, because the
programme
IBR_SimKey
outputs the measurement values over the keyboard buffer.
