CH9120 Network TTL Serial Port Module Serial Port

CH9120 Network TTL Serial Port Module Serial Port Description

1. Supports bidirectional transparent transmission of serial port data and network data
2. Supports Server, Client, UDP Client, and UDP Server operating modes;
3. Supports a 10M, full-duplex/half-duplex auto-sensing Ethernet interface, compatible with the 802.3 standard;
4. Supports automatic /MDIX line conversion;
5. Supports automatic IP address acquisition via DHCP;

Supports chip parameter configuration via software and serial port;
Supports the KEEPALIVE mechanism;
Supports serial port baud rates from 300BPS to 921600BPS
Client Mode:In Client mode, upon power-up, the module actively connect to the Server. Once the connection is established, bidirectional transparent transmission of network and serial port data is possible. The client application model is as follows: Suitable for field data acquisition and upload server mode.
TCPSERVER Mode: In TCPSERVER mode, after powering on, the module monitor the local port for client connection requests. Once a connection is established, bidirectional transparent transmission of network and serial port data is possible.
UDPCLIENT Mode: In UDPCLIENT mode, after powering on, the module transparently forwards data sent to the local port (from the destination IP and port) to the module's serial port. Similarly, data sent to the module's serial port is forwarded via UDP to the specified destination IP and port.
UDPSERVER Mode: In UDPSERVER mode, all data sent to the local IP and port is received and forwarded to the serial port. Data sent to the module's serial port is also forwarded via UDP to the corresponding UDP IP and port.
