Powerful Wireless Connectivity

The DAP142 supports the Wi-Fi 4 standard (802.11b/g/n) and can operate as an Access Point, Client, Mesh node (802.11s), or in Multi-AP mode. With support for up to 50 simultaneous clients, it is ideal for demanding industrial environments. Fast Roaming (802.11r) and BSS Transition Management (802.11v) minimize connection drops for mobile devices, while Radio Resource Measurement (802.11k) optimizes radio utilization. ESSID Stealth Mode and Wireless MAC Filtering (Allowlist/Blocklist) enhance access control. Wireless security is ensured through WPA-PSK, WPA2-PSK, WPA3-SAE, WPA-EAP, WPA2-EAP, WPA3-EAP, and OWE.

Robust Industrial Design and Flexible Power Supply

The compact aluminium housing (113.10 x 25 x 68.6 mm, 149.2 g) with IP30 protection is designed for use in harsh environments. Its operating temperature range of -40 °C to 75 °C and humidity tolerance of 10% to 90% (non-condensing) ensure reliable continuous operation. The integrated DIN rail mounting allows for quick installation in control cabinets; wall and flat-surface mounting are also available as options. Power is supplied via a 3-pin terminal block (9–30 VDC) with reverse polarity and overvoltage protection (>31 VDC, 10 µs max.). Alternatively, the device can be powered passively via PoE on LAN2 (9–30 VDC, Mode B). Power consumption is 1 W in idle mode and up to 2 W at maximum load.

Security and VPN Integration

The DAP142 features a multi-layered security architecture. Authentication supports pre-shared keys, digital certificates (X.509), TACACS+, and both internal and external RADIUS servers. Integrated attack detection prevents DDoS attacks (SYN Flood, SSH/HTTP/HTTPS attacks) and port scans (SYN-FIN, SYN-RST, X-mas, NULL, FIN). VLAN segmentation (port- and tag-based) and a Web Filter with black-/whitelisting further enhance access control. For secure site-to-site connectivity, numerous VPN protocols are available: OpenVPN (27 encryption methods), IPsec (IKEv1/v2, 14 ciphers), WireGuard, ZeroTier, DMVPN (Phase 2/3, Dual Hub), SSTP, L2TPv3/L2TP over IPsec, PPTP, GRE (including over IPsec), Stunnel, Tinc, and Tailscale. Dynamic routing (BGP, OSPFv2, RIP, EIGRP, NHRP) and policy-based routing ensure flexible traffic management.
