<br />
== Technical overview ==<br />
* Power input: DC 5 V to 36 V via screw terminals.<br />
* Transmission rate: stable at 300 to 115200 baud.<br />
* Isolation: unibody digital signal and power isolation without external power at the isolated terminal.<br />
* Protection circuitry: onboard TVS against overvoltage, lightningproof with 600 W rating, and ESD protection (15 kV).<br />
* Additional protection: self-recovery fuse and protection diodes against overcurrent and overvoltage.<br />
* RS485 output terminal with optional 120-ohm resistor, enabled via jumper.<br />
* Indicator LEDs: PWR (red), TXD (green), RXD (blue) indicate power, transmit, and receive activity.<br />
* Enclosure: ABS, suitable for 35 mm DIN rail; dimensions 91.6 x 58.7 x 23.3 mm.<br />
<br />
== Notes and version constraints ==<br />
* The exact pinout and precise jumper positions must be confirmed on the physical device.<br />
* When using multiple nodes in point-to-multipoint mode, a relay may be required to keep the node count within the 16-node limit.<br />
* Proper grounding connections (SGND/GND) must be verified before commissioning.<br />
* Compatibility with existing RS232 devices should be validated in the target system.<br />
* Protection ratings (e.g., 600 W lightningproof) are based on manufacturer claims and should be independently validated for critical applications.<br />
