Ask for a sample or a small pilot. Availability, minimum quantity and sample charges depend on the selected model.
Price & delivery
Range, interface, accessories, quantity and destination affect the quote. Stock, lead time, freight, taxes and delivery terms need confirmation.
Warranty & support
Coverage, duration, exclusions and the fault-assessment process are confirmed for the quoted model before order.
Certificates & documents
Tell us the destination and required standard. We check the exact model, document revision and available evidence; a family listing is not certification.
Public documents describe this product family and selection options. Wiring, register maps and compliance documents must match the model and version selected for your order.

Need documents for engineering or purchasing?
Choose what you need. We first identify the model and revision, then confirm which documents can be supplied. The request does not imply that every document is available.

Count independent serial loops first. One, two and eight-port families are available, and separate baud rates or framing settings may require separate ports.
Confirm whether each serial line uses RS485, RS232 or RS422, plus baud rate, parity, stop bits, device addresses and termination.
Define the Ethernet-side role: transparent TCP or UDP transport, Modbus RTU-to-TCP gateway, HTTP, or MQTT on a documented variant.
Estimate device count, register count, polling interval, timeout and retry behavior before the pilot.

Confirm the panel Ethernet speed, IP addressing, firewall rules and who owns network commissioning.
Select DC 8–28 V, PoE or an applicable AC variant from the final family configuration; do not assume every power option is available in every enclosure.
Compatible with
RS485, RS232 or RS422 field devices, selected by configuration
Modbus RTU devices and Modbus TCP clients or servers
Ethernet networks using TCP or UDP
HTTP or MQTT applications on documented family variants
Typical package
Selected 1-, 2- or 8-port serial-server configuration
DC power supply or the applicable PoE / AC option
Serial wiring, termination and Ethernet patching
IP plan, serial settings, register map and commissioning test
Applications
I/O, protocol, antenna, power, enclosure and upstream platform are selected for the project.
Use this family when installed serial devices need a direct Ethernet path without replacing the PLC, meter, sensor or controller. Select the port count, serial interface, Ethernet speed and protocol role from the actual field wiring and upstream system.
Bridge Modbus RTU devices to Modbus TCP
Tunnel serial data over TCP or UDP
Separate multiple serial loops with 2- or 8-port configurations
Use HTTP or MQTT on the family variants that document those functions
It connects an installed serial device or serial bus to an IP network. Depending on the selected configuration, it can tunnel serial data over TCP or UDP or bridge Modbus RTU devices to Modbus TCP.
How many serial ports are available?
The reviewed family includes 1-port, 2-port and 8-port configurations. Share the number of independent serial loops, devices per loop and serial settings so the correct option can be selected.
Does it support Modbus RTU and Modbus TCP?
Yes. Modbus RTU/TCP gateway operation is part of the reviewed family scope. The device role, register workload, polling behavior and timeout settings still need to be confirmed for the project.
Does every configuration support MQTT or HTTP?
No. HTTP and MQTT are documented on selected families, not every enclosure or interface option. State the required upstream protocol in the RFQ so the quotation can name the matching configuration.
Is this the same as an edge IoT gateway?
No. This family is intended for direct serial-to-Ethernet conversion and Modbus bridging. Use an edge IoT gateway when the project needs broader protocol handling, cellular backhaul, local processing or a reviewed outage queue.
Does this family include BACnet?
BACnet is not part of the approved public facts for this family. If the BMS requires BACnet, include the BACnet object and version requirements in the RFQ so a separately verified gateway can be selected.
Can an RS485 Modbus data acquisition gateway connect existing meters to MQTT or SCADA?
Yes when device roles, register maps, baud rate, polling load and the upstream protocol are documented. The gateway maps field devices; it does not invent a dashboard. Share the destination MQTT, Modbus TCP or API details before quotation.
Is RS485 the same as Modbus RTU for industrial data acquisition?
No. RS485 is the electrical bus. Modbus RTU is a protocol commonly used on that bus. A quotation should confirm both the wiring and the register map, plus any Ethernet or MQTT handoff on the upstream side.
What should I provide when requesting a quote for the RS485 to Ethernet Gateway / Serial Server?
Serial interface, independent loop count and device count per loop; Baud rate, parity, stop bits, addresses and register list; Required Ethernet role: transparent TCP / UDP, Modbus TCP, HTTP or MQTT; Ethernet speed, IP plan, firewall and commissioning ownership
Where can I compare available model options?
Open the Industrial Monitoring Hardware Catalog linked on this page. Use it to compare equipment options before requesting a configuration.
Will it work with my existing system?
Compatibility is reviewed against your field signals, protocols and upstream platform. Typical pairings include RS485, RS232 or RS422 field devices, selected by configuration, Modbus RTU devices and Modbus TCP clients or servers, Ethernet networks using TCP or UDP.
Product-family reference. Final ordered model and specifications are confirmed in the written quotation.
