Vonets VAP11S-D232 Industrial Dual-Band WiFi Serial Port

The VONETS VAP11S-D232 is an industrial dual-band 2.4GHz/5GHz WiFi serial port server, bridge and repeater that converts wired/serial devices to wireless networks and extends WiFi coverage for machines and equipment.

This compact industrial router/bridge is built to connect RS-232/TTL serial devices and Ethernet equipment to modern WiFi networks, offering flexible power options and multiple operating modes. It supports 802.11a/b/g/n/ac on dual bands, transparent serial-to-Ethernet transmission and a range of physical interfaces so legacy hardware like medical instruments, PLCs, printers and AGVs can communicate over WiFi without redesign.

How does this device connect serial or Ethernet devices to WiFi?

The VAP11S-D232 acts as a WiFi-to-wired or wired-to-WiFi converter and a serial port server. It maps serial data into Ethernet packets (and vice versa) with support for one-to-one and one-to-many transparent transmission, plus MAC-layer or IP-layer bridging for advanced scenarios.

• Dual UART TTL serial ports and optional RS-232/RS-485 hardware interfaces
• One 10/100 Mbps adaptive Ethernet port for LAN/WAN use
• Transparent serial-to-Ethernet forwarding (UDP broadcasting allowed)
• Supports MAC-layer and IP-layer bridge modes for encrypted or legacy setups

Which wireless speeds and bands are supported?

The unit runs on both 2.4GHz and 5GHz bands, supporting 802.11b/g/n/a/ac standards to balance compatibility and throughput. The theoretical data rates list 300 Mbps on 2.4GHz and up to 900 Mbps on 5GHz, making it suitable for high-throughput device links and stable control channels.

• Dual-band operation: 2.4GHz and 5GHz for flexibility
• Standards: 802.11b/g/n/a/ac for broad device compatibility
• Theoretical rates: ~300 Mbps (2.4GHz) and ~900 Mbps (5GHz)
• Works as WiFi AP, repeater, bridge, or router (WiFi WAN supported)

What power and mounting options are available?

The VONETS unit accepts a wide DC input range and can run from standard USB or dedicated DC supplies, with built-in overvoltage protection to suit industrial environments. That makes it simple to power from common 5V or 12V sources used in control cabinets or mobile robots.

• Supports DC 5V–24V; typical supplies: 5V/2A or 12V/1A
• USB power option for flexible deployments
• Two-level automatic overvoltage protection; 27V protection point
• Small form factor for DIN-rail, cabinet or device-side mounting

Which devices and industries benefit from the VAP11S-D232?

This bridge/server is designed for legacy and industrial equipment that lack native WiFi: medical monitors, AGVs, industrial PLCs, cameras, scales, printers and research instruments. It provides a low-effort path to wireless connectivity without replacing field hardware or reengineering serial protocols.

• Medical devices, lab equipment and patient monitors requiring network access
• AGVs, robots and industrial automation with serial or Ethernet interfaces
• IP cameras, DVRs, network printers and IoT gateways in retrofit projects
• Environments needing repeater or AP hotspots to extend coverage

Who is this for: engineers, system integrators and IT administrators who need a reliable, compact wireless bridge/serial-server to connect legacy RS-232/TTL devices and Ethernet equipment to modern WiFi networks. If you manage medical hardware, factory automation, robotics or retrofit IoT projects and want minimal changes to existing cabling or firmware, the VONETS VAP11S-D232 is engineered to simplify deployment and maintain industrial-grade power tolerance and interface flexibility.
