1-Port Extender

HDH-EXT100

This network serial port expander can communicate with the programm￾able central control system or PC to control multiple devices, and perform protocol conversion between various devices with different communication modes. It supports TCP/UDP protocol, and the output serial port supports RS-232/RS-485 protocol. IR output, GPIO input/output and POE function are supported. The front panel of the expander is designed with LED indicators for power supply, serial port sending/receiving data, which can conveniently and quickly indicate the progress of data communication and equipment power failure. 

☆ The power input is designed with a wide voltage range (12-24V)

☆ Dual power supply modes, supporting DC or POE power supply 

☆ Product parameters can be modified through API commands

☆ Built-in web server, allowing users to directly log in to web pages through various computer, tablet, and mobile device browsers to view system status or configure device parameters

☆ 1x 100M adaptive Ethernet port, supporting TCP/UDP mode communication (TCP mode is used by default, UDP is disabled)

☆ 1x GPIO input/output port (input mode by default, can be configured to output mode through Web GUI or API commands)

☆ 1x IR output port (5V level), supporting CCF code protocol forwarding

☆ 1x RS-232/RS-485 multiplexed communication port, with optional baud rates of 2400-115200

☆ Both RS-232 and RS-485 serial ports support data bits (8 bits), parity bits (odd, even, none) and stop bits (1, 2 bits) settings

☆ Support RS-232/RS-485 mode switching: 

 When selecting RS-232 mode, the RS-485 serial port is disabled; 

 When selecting RS-485 mode, the RS-232 serial port is disabled.
