The ATRx10 ProxTime Terminal communicates to the PC via RS232. The ATRx20 ProxTime Secondary Terminal communicates to the ATRx10 Terminal via RS485. Neither terminal is 802.11b or 802.11g (wireless Ethernet) compatible.
However, the computer to which the ATRx10 Terminal is connected may communicate with your network using one of these wireless Ethernet standards if your network supports them.[contact-support][support-contracts]
