It is a highly compact and rugged wireless unit that integrates two access points, a managed fiber switch, and a wide-range AC/DC power supply, all in one box. The IP68 housing can withstand the harshest weather, and M12 connectors make the unit shock and vibration resistant. The TAP-6226 supports advanced controller-based Turbo Roaming technology for applications such as Communication-Based Train Control (CBTC). The unit can supply power to up to 4 PoE devices while providing reliable LAN communication with Moxa’s Turbo Chain technology.
