VONETS VAP11S-232 Industrial 2.4GHz WiFi Bridge to Serial RS232/RS485/TTL, Wireless to Ethernet Adapter, 5-24V Wide Voltage, 300Mbps for PLC/Modbus/Industrial Control/Data Acquisition

The VONETS VAP11S-232 is an industrial-grade 2.4GHz WiFi Bridge, Repeater, and Serial-to-Ethernet Server designed to bring legacy serial devices online wirelessly. Whether you need to connect a PLC, Modbus meter, industrial sensor, or RS232 controller to a modern WiFi network, the VAP11S-232 provides reliable, secure, and long-range connectivity.Key Function – Serial to WiFi/Ethernet:The VAP11S-232 converts RS232, RS485, or TTL serial signals to WiFi or Ethernet packets. It supports both one-to-one and one-to-many serial transparent transmission – a significant advantage over ordinary modules that only support one-to-one. This allows a single serial device to communicate with multiple servers, or multiple serial devices to share one wireless bridge.Serial Interface Details:One RJ45 female socket providing 2 UART serial ports (TTL level: 3.3V LVTTL or 3.3V CMOS)Optional accessories (sold separately):RS232: DB9-232 adapter or VDB9-232-X2 (built-in RS232 chip)RS485/RS422: VRJ45-422-1 (built-in chip with toggle switch)TTL (3.3V): VRJ45-5P adapterPerfect for PLC programming, Modbus RTU/ASCII, data acquisition, and industrial control systems

• 【MAC Layer Transparent Bridge + Serial to IP】 Supports both IP-layer and MAC-layer transparent bridging – solves connectivity with AC-managed APs. The RJ45 female socket provides 2 UART serial ports (TTL 3.3V / CMOS 3.3V). Optional accessories available for RS232 (DB9-232) or RS485/RS422 (VRJ45-422-1) conversion.
• 【Industrial WiFi to Serial Bridge】 The VAP11S-232 converts RS232/RS485/TTL serial signals to WiFi or Ethernet. It bridges legacy serial devices (PLCs, meters, sensors, industrial controllers) to a wireless network. Supports one-to-one and one-to-many serial transparent transmission – many modules only support one-to-one.
• 【Wide Voltage 5-24V & DIN Rail Mount】 Accepts DC 5V to 24V input with two-stage overvoltage protection (triggers at 29V). Comes with standard industrial DIN rail mounting kit and industrial DC power connector. Perfect for factory control panels, automation cabinets, and field installations.
• 【Reliable 2.4GHz WiFi】 Delivers 300Mbps wireless speed (802.11b/g/n). With 2 external 3dBi antennas and selectable TX power (19/23dBm), achieves point-to-point line-of-sight range up to 300 meters. Built-in digital-analog temperature compensation for stable signal without dropouts.
• 【Smart for Industrial Use】 Memorizes up to 100 hotspots with auto-reconnect. Supports 20+ simultaneous WiFi terminals. Features WEB management (Chinese/English), VDNS for easy setup, SSA signal strength detection, manual SSID/WiFi shutdown, and configuration parameter import/export for batch deployment.
