Network Serial Port Expander: Overview and Protocol Conversion
The Network Serial Port Expander is a versatile device featuring four extended serial ports designed to perform protocol conversion between various equipment with different communication modes. It acts as a bridge between serial and network communication, supporting two distinct modes where it can function as either a TCP or UDP server to listen for connection requests. This allows the expander to communicate seamlessly with programmable central control systems or PCs to manage multiple third-party devices from brands like AMX, Crestron, and RTI.
Network Serial Port Expander: Technical and Hardware Specifications
This Network Serial Port Expander is housed in a durable black metal enclosure and supports a wide range of serial standards, including RS-232, RS-422 full duplex, and RS-485 half duplex. It provides one 100M Ethernet interface and supports baud rates ranging from 2400 to 115200. Additionally, the hardware includes four low-voltage, independent relay ports with normally open contacts, and is powered by a 24V/1A DC input.
Network Serial Port Expander: Operation and Management
The Network Serial Port Expander features a front panel with LED indicators for power, relay status, and data transmission/reception across all serial ports. For system management, it includes a built-in Web server that allows users to configure device parameters directly through a browser on computers, tablets, or mobile devices. It also supports ASCII command control for single-machine or cascading configurations, enabling advanced system settings such as network IP addresses, gateway settings, and port-specific data bit configurations.
