Read/write device

Technical data Function

General specifications

The read/write device establishes theconnection between the code and/or datacarriers of the Ident-M System T and a higher-order computer (industrial-PC, PLC,etc.). Communication with the computeroccurs via an RS 232 or RS 485 (2- or 4-wire) serial interface.The system is multitag capable, i.e. severalcode or data carriers are identified within the sensing range. The write/read devices canbe set to 100 different frequency channels,thereby preventing mutual interference. Due to their internal data base as well asdifferent inputs and outputs, the devices canalso be used in stand-alone operation. An LED as well as a buzzer integrated in thedevice indicate the operating status.The device can be adjusted and tested via an internal control panel with two pushbutton switches and two 7-segment displays. The device is delivered ex works with the 'Confitalk' protocol software. Defined in thisprotocol are a wide range of commandswhich allow the user to perform simplecommunication operations between thehigher-order computer and the read/writedevice. The device offers an increased readdistance of 6 m. Additional information can be found in thedescriptions of the system and device. Operating frequency 2,435 ... 2,465 GHz 100 ID channels, channel separa- tion 300 kHzPolarisation circular Transfer rate read: 4 kBit/s , 16 kBit/s write: 4 kBit/sAcquisition range of the motion recognition 5 m for velocities between 0.3 and 9.2 m/s
