• Sequentially Scans up to 4 x CRx Readers
  • Produces a Single RS232 Output
  • Allows Independent Readers to Work Close to One Another
  • CE, DTI & FCC Approved


The BB-MUX Multiplexer is used where a number of readers are installed close to one another such that the detection fields overlap. The BB-MUX sequentially activates each reader in turn to scan for tags. The BB-MUX is capable of controlling up to 4 x CRx readers with each reader having its own output
Since each reader is only active for the scan time, the overall detection speed of each reader appears to be slower. Each reader is configured with its own unique output (Wiegand or Clock/Data) connection to the BB-MUX uses the RS232 output. The unit is suitable for use with all CRx models with the exception of the CR1-MPX. Please note all CRx readers connected to the BB-MUX must be programmed with the appropriate firmware.
