2. Support wide voltage DC5V-24V power supply, two-stage automatic overvoltage protection, overvoltage protection point 29V;
3. Support 802.11b/g/n/a/ac WiFi transmission protocol;
4. Wireless transmission rate: 300Mbps+900Mbps;
5. Transmission power: 2.4G is 15dBm, 5G is 19dBm/23dBm, optional;
6. Maximum point-to-point obstacle free transmission distance: 802.11A 200 meters;
7. One 10/100Mbps adaptive Ethernet port, one RJ45 motherboard (UART serial port: supporting TTL level (LVTTL-3.3V) or CMOS level - 3.3V), VDB9-232 (optional): RJ45 to DB9 motherboard (line built-in chip to RS232 level), RJ45 to 5Pin wiring base, VRJ45-422-1 (built-in RS485/RS422 chip, with toggle switch switching, supporting TTL level (3.3V);
8. Standard industrial rail fixing kit and industrial power DC connector;
9. WiFi hotspot memory, with a maximum memory of 100 hotspots;
10. Supports simultaneous connection of more than 20 WiFi terminal devices;
11. Adopt VDNS virtual domain name configuration technology to alleviate user configuration difficulties;
12. Support manual shutdown of SSID broadcast and WiFi hardware;

14. Support the import and export of configuration parameters to facilitate batch configuration of engineering projects;
15. Serial port transparent transmission (serial port data to Ethernet data packets) supports one-to-one transparent transmission and one-to-many transparent transmission. Ordinary transparent transmission modules only support one-to-one transparent transmission;
16. Supports two bridge modes, IP layer transparent transmission and MAC layer transparent transmission, to meet various bridge applications;
17. IP layer transparent transmission (factory default), transparent transmission of IP layer data, can meet most bridge applications;
18. The MAC layer transparently transmits all data at the MAC layer (link layer) and above, including IP layer data. MAC passthrough can solve some special applications for MAC layer encryption, such as AP managed by AC, GoPro camera, Cisco AP, Hikvision monitoring system, etc.
19. Using digital analog temperature compensation frequency stabilization technology, WiFi signals are more stable and not easy to drop;
20. Working ambient temperature: - 20 ℃ to 55 ℃.
