== Summary ==
A rail-mount serial server that converts RS232/485/422 serial signals to TCP/IP via an RJ45 Ethernet module with optional PoE power. It functions as an IoT gateway and Modbus gateway for industrial data acquisition.

== Technical overview ==
* Interfaces: 1 isolated RS232/485/422 port, 1 10/100 Mbit/s RJ45 Ethernet port with 2 kV surge protection; PoE (IEEE 802.3af) is only available on models labeled “POE”
* Power: screw terminals accepting DC 6–36 V or PoE through the network port; barrel connector outer diameter 5.5 mm, inner diameter 2.1 mm
* Serial parameters: baud rates 300–115200 bps, 5–9 data bits, parity none/odd/even/mark/space, no flow control
* Operating modes: TCP server (up to 30 concurrent connections), TCP client (up to 7 destination IPs), UDP, and UDP multicast; TCP client also supports a coexisting TCP server function
* Protocols: ETHERNET, IP, TCP, UDP, HTTP, ARP, ICMP, DHCP, DNS; configuration via PC software, web browser, or device-management library
* Advanced features: Modbus RTU-to-TCP gateway (storage and non-storage modes), MQTT gateway, JSON-to-Modbus RTU/645 meter protocol, NTP time sync, custom heartbeat/registration packets, password authentication for TCP connections
* Dimensions: 88.7 × 64.5 × 24.2 mm; operating temperature −40 °C to 85 °C; humidity 5–95 % RH

== Notes and version constraints ==
* The IP addresses mentioned in the source (e.g., 192.168.1.200, ports 4196 and 1111) are example values from a test environment, not fixed defaults of the device.
* The exact maximum current draw when powered directly at 24 V is not stated in the source; only a measurement at 12 V (0.96 A, 1.16 W) is given.
* Firmware-specific configuration files (e.g., the 2043 web interface) must be re-downloaded depending on installed firmware; details depend on the specific firmware version.
* RS485 wiring: short-distance links may work without 120 Ω termination resistors; multi-point long-distance buses should have 120 Ω resistors at both ends — exact placement must be verified on site.
* If the web configuration page will not open because another firmware (MQTT, Jetson Modbus) overwrote the config files, manually re-downloading the correct web file is required.
