Description

The Teltonika DAP142+RS232 is engineered for mission-critical industrial wireless networking, combining robust Wi-Fi 4 connectivity with essential serial communication. Its Mediatek 580 MHz MIPS CPU and 128 MB RAM handle concurrent routing, VPN tunneling, and firewall tasks, ensuring reliable data backhaul from sensors and PLCs. The integrated RS232 port bridges legacy industrial equipment to modern IP networks, enabling seamless data aggregation and remote management.

Built to withstand extreme conditions, the unit’s aluminum chassis and wide-temperature components guarantee operation in manufacturing floors, utility substations, and outdoor enclosures. Network architects benefit from features like static/dynamic routing, DDNS, load balancing, and support for multiple VPN protocols (OpenVPN, IPsec, WireGuard), allowing secure integration into existing enterprise or cloud infrastructures. The inclusion of passive PoE simplifies installation by delivering power and data over a single Ethernet cable.

Key Features

  • Industrial-grade 802.11b/g/n Wi-Fi Access Point with support for Wi-Fi Mesh and Fast Roaming for seamless coverage.
  • Integrated RS232 serial port enables connectivity with legacy industrial devices like PLCs, meters, and SCADA systems.
  • Ruggedized design with aluminum housing, DIN-rail mounting, and operation from -40°C to 75°C at 10-90% humidity.
  • Advanced network security suite including WPA3 encryption, configurable firewall, VPN support (OpenVPN/IPsec/WireGuard), and MAC filtering.
  • Flexible power input from 9-30 VDC with reverse polarity and surge protection, plus passive PoE support over LAN port.
  • Comprehensive management via web-based GUI, SSH command line, TR-069 ACS, or the Teltonika Remote Management System (RMS).
  • Dual 10/100 Mbps Ethernet ports for network segmentation, WAN/LAN configuration, or daisy-chaining devices.
  • Supports static/dynamic routing, DDNS, MQTT for IoT data publishing, and load balancing for network redundancy.

Applications

  • Industrial automation networks for connecting PLCs, HMIs, and sensors via Wi-Fi and serial backhaul.
  • Remote telemetry and SCADA systems in utilities, water treatment, and oil & gas for data aggregation.
  • Building management systems (BMS) and HVAC control leveraging RS232 for legacy device integration.
  • Transportation and traffic management networks for roadside equipment connectivity.
  • Secure wireless bridges in manufacturing plants and warehouses for machine and inventory tracking.

Frequently Asked Questions

How do I configure the RS232 serial port on the DAP142 for my PLC communication?

Access the DAP142 web interface and navigate to the 'Serial Port' configuration section. Set the baud rate, data bits, parity, and stop bits to match your PLC's UART settings (common values are 9600 8N1). You can then configure serial-to-TCP/IP bridging or raw socket forwarding to route the PLC data over Ethernet or Wi-Fi to your SCADA server or MQTT broker.

What is the procedure for setting up a secure site-to-site VPN with the DAP142?

In the DAP142's web UI under 'VPN', select either OpenVPN or IPsec. For OpenVPN, generate certificates on your server, upload the client config file and keys to the DAP142. For IPsec, define Phase 1 (IKE) and Phase 2 (ESP) parameters matching your remote gateway. Ensure firewall rules permit VPN traffic and define the remote subnet for routing. The unit supports persistent tunnels for always-on industrial connectivity.

Can the DAP142 be powered via Passive PoE from a switch, and what are the pinouts?

Yes, the DAP142 supports passive PoE injection via its LAN1 port. The standard pinout uses the data pairs: V+ on pins 4 & 5 and V- on pins 7 & 8. Ensure your passive PoE injector or switch provides 9-30 VDC within this specification. Always verify polarity before connecting. The device includes built-in surge and reverse polarity protection for safety.
