The routing switches WR309 series include WR309 with 8-Port Ethernet and 1 GbE WAN port, WR309P-with 8-port PoE+ boost up to 30W/port for bus/vehicle, WR309A with 1 RS232/422/485 serial port, 3 DIs and 2 DOs for IoT sensors, DIO applications and WR309PA for both PoE and IoT features. The security design includes static routing, IPSec VPN, DMZ, and a stateful firewall inspection in order to segregate networks and protect mission-critical data. With support for Network Address Translation (NAT) and port-forwarding, it isolates the threats from the Internet. The USB port for configuration can help mass installation and site support. The embedded MQTT and RESTful API enables public cloud integration such as AWS®, Azure®, or user-defined cloud. The private cloud platform ThingsMaster® by WoMaster can also be set up for an instant and secured access for video surveillance and IoT control over the cloud.
