Mahr i-Stick Wireless USB Receiver 4102220 inkl. MarCom Standard. With the integrated wireless receiver up to 8 digital indicators can be connected per i-stick, therefore expensive interface boxes are no longer required. When just attaching a digital indicator you have already a wireless data transmission for the price of a data cable. With the integrated wireless your data will be transferred to the digital indicator; this is confirmed with a message in the digital indicator's display to whether the sent data has been transferred correctly, and-or whether you are in the reception range of the i-stick.
