Featured Highlights
The main serial port only supports RS-232; Extended serial port 1 and extended serial port 2 support RS-232, RS-232+ Hardware Flow, RS-422 full duplex, and RS-485 half duplex; Extended serial port 3 and extended serial port 4 support RS-232 and RS-232+ hardware flow control
All serial ports support baud rate (2400, 4800, 9600, 14400, 19200, 38400, 5600, 57600, 115200)
All serial ports support data bits (7, 8 bits), parity bits (odd, even, none), stop bits (1, 2 bits), and settings.
Large buffering space for data transmitting and receiving is reserved for each serial port; the data queue is supported.
Each frame of data can support up to 512 bytes.
Device parameters can be configured through the main serial port, TCP and UDP:
a. In TCP mode, the TCP port for the device configuration function is 8005.
b. In UDP mode, the UDP local port for the device configuration function is 9005, and the default remote port is 1005.
Extended serial port data can be sent and received over TCP or UDP:
a. In TCP mode, the TCP ports corresponding to the extended serial ports 1~4 are 8001, 8002, 8003, and 8004.
b. In UDP mode, the UDP local ports corresponding to the extended serial ports 1~4 are 9001, 9002, 9003, and 9004. The default remote ports are 1001, 1002, 1003, and 1004. API commands or the Web configuration page can modify the remote port.
Provide one 100M Ethernet communication port and one RS-232 port, which can be connected to a computer or central control system compatible with all third-party central control systems such as AMX, CRESTRON, RTI, etc.
Support 4 low-voltage relay ports, normally open contacts; each group is independent and isolated, maximum of 1A 24V DC/AC loading
Built-in Web server, which can configure device parameters directly through the browser of various computers, tablets, and mobile devices
