The top panel features an SMA-K RF connector for external 2.4G\/5.8G high-gain rubber duck or magnetic whip antennas. Industrial 5.08mm pluggable screw terminals provide robust electrical connections: wire serial data to RS485-A and RS485-B terminals. For DC models (NA611, NA611-S, E103-W02DTU), connect DC 8~28V power to V+ and V- terminals. For AC models (NA611-A), connect AC 85~265V live (L) and neutral (N) wires directly. Five diagnostic LEDs provide clear real-time monitoring: PWR (Power), STATE (Fault\/Status), DATA (Serial\/WiFi RX\/TX), LINKA (WiFi Connection Status), and LINKB (Server Cloud Connection Status).\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_12_ce9b20a9-32ed-4865-b45b-0e376d13952b.jpg?v=1793180914\" alt=\"Ebyte NA611 Series Installation \u0026amp; Wiring - 1 (12).jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_13_ea44c4c3-2d48-4634-8072-e71d6303778a.jpg?v=1793180914\" alt=\"Ebyte NA611 Series Installation \u0026amp; Wiring - 1 (13).jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_14_766c4b3a-fe99-4586-9bcf-3c469d11a770.jpg?v=1793180914\" alt=\"Ebyte NA611 Series Installation \u0026amp; Wiring - 1 (14).jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_15_8eefa49c-1270-4e02-9939-6745d3b5ed8c.jpg?v=1793180914\" alt=\"Ebyte NA611 Series Installation \u0026amp; Wiring - 1 (15).jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_16_edd7af77-2b07-4252-a01c-77a3235fc3f7.jpg?v=1793180914\" alt=\"Ebyte NA611 Series Installation \u0026amp; Wiring - 1 (16).jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cdiv class=\"ebyte-text-specs\" style=\"margin-top: 30px;\"\u003e\n\u003ch2\u003ePractical Application Scenarios\u003c\/h2\u003e\n\u003ch3\u003e1. Factory Floor CNC Machine Tool \u0026amp; PLC Wireless SCADA Networking\u003c\/h3\u003e\n\u003cp\u003eIn manufacturing workshops where running Ethernet cabling across machine shop floors is difficult and expensive, installing the NA611 dual-band WiFi serial server on CNC controllers, Siemens S7-200\/1200 PLCs, and touchscreens allows instant wireless integration into the plant 5.8GHz high-speed Wi-Fi network, eliminating 2.4GHz co-channel interference and providing stable SCADA telemetry.\u003c\/p\u003e\n\u003ch3\u003e2. Smart Photovoltaic Inverter \u0026amp; Battery Storage (BESS) Wireless Monitoring\u003c\/h3\u003e\n\u003cp\u003eSolar solar farms and distributed energy storage cabinets utilize RS485 Modbus RTU strings to monitor power generation and battery state-of-charge. Deploying the NA611-S with 4-way Sockets enables simultaneous local HMI telemetry and remote cloud platform synchronization over MQTT, ensuring continuous inverter telemetry without physical trenching.\u003c\/p\u003e\n\u003ch3\u003e3. Agricultural Greenhouse Environmental Sensing \u0026amp; Automated Valve Control\u003c\/h3\u003e\n\u003cp\u003eIn large-scale smart agricultural greenhouses, RS485 soil moisture sensors, weather stations, and irrigation pump controllers are widely dispersed. Utilizing the Ebyte NA611 series in Station (STA) mode bridges all Modbus RTU sensors back to the central environmental controller over wireless Wi-Fi, dramatically reducing field installation labor.\u003c\/p\u003e\n\u003ch3\u003e4. Commercial Building HVAC \u0026amp; Smart Energy Submetering\u003c\/h3\u003e\n\u003cp\u003eRetrofitting energy submeters and chiller unit controllers in commercial buildings frequently encounters physical cable routing barriers. Installing the NA611-A with AC 85~265V direct line power allows power meters to be connected directly to existing AC distribution boards without auxiliary DC adapters, streaming submetering data straight to the building energy management software.\u003c\/p\u003e\n\u003ch2\u003eFAQ Section\u003c\/h2\u003e\n\u003ch3\u003e1. What are the key advantages of 5.8GHz WiFi on NA611 and NA611-A compared to 2.4GHz?\u003c\/h3\u003e\n\u003cp\u003eThe 2.4GHz ISM band in industrial environments is heavily crowded with Bluetooth, ZigBee, and common wireless devices. The 5.8GHz frequency band on NA611 \/ NA611-A offers significantly higher bandwidth, cleaner channels, and immunity from 2.4GHz co-channel interference, ensuring deterministic low-latency serial data transmission for critical automation controls.\u003c\/p\u003e\n\u003ch3\u003e2. How do I configure the NA611 serial server parameters (SSID, IP, baud rate)?\u003c\/h3\u003e\n\u003cp\u003eThe NA611 series supports multiple convenient configuration methods: web browser HTTP management page, standard AT command set via serial port, and Ebyte's free graphical Network Configuration Tool via UDP broadcast, enabling rapid multi-device batch deployment without manual IP reconfiguration.\u003c\/p\u003e\n\u003ch3\u003e3. How does the 4-way Socket feature operate on the NA611-S?\u003c\/h3\u003e\n\u003cp\u003eThe 4-way Socket feature allows the NA611-S to establish up to 4 simultaneous independent TCP\/UDP client connections to different IP servers or cloud endpoints. Serial data received from the RS485 port is intelligently distributed or mirrored across all 4 active socket links according to your configuration.\u003c\/p\u003e\n\u003ch3\u003e4. How do I restore the device to factory default settings?\u003c\/h3\u003e\n\u003cp\u003eEach NA611 unit is equipped with a hardware RESTORE button. To reset the device, press and hold the RESTORE button for approximately 5 seconds while powered on; all status indicators will flash and the device will restart with factory default IP address, SSID, and 9600 bps baud rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Ebyte Official Store - IoT Module Manufacturer","offers":[{"title":"NA611","offer_id":48846901313741,"sku":"NA611","price":0.0,"currency_code":"USD","in_stock":true},{"title":"NA611-A","offer_id":48846901346509,"sku":"NA611-A","price":0.0,"currency_code":"USD","in_stock":true},{"title":"NA611-S","offer_id":48846901379277,"sku":"NA611-S","price":0.0,"currency_code":"USD","in_stock":true},{"title":"E103-W02DTU","offer_id":48846901412045,"sku":"E103-W02DTU","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/01_90156179-04f8-4437-a007-cfc78fc7f852.jpg?v=1793180934","url":"https:\/\/ebyteiot.com\/hi\/products\/na611-series-industrial-wifi-serial-server-rs485-dual-band","provider":"Ebyte Official Store - IoT Module Manufacturer","version":"1.0","type":"link"}
