Overview
ZLSN2000 is a 19-pin double-row module with a size of only 43mm ¡¿ 26mm, which can be integrated into the user's PCB circuit, and only needs a few expansion circuits to realize the networking of embedded devices. ZLSN2000 has the function of full-duplex, uninterrupted transmission (under 115200 baud rate, two-way uninterrupted simultaneous transmission of large batches of data without losing a byte), stable performance and moderate price. Users only need to connect their pins to the serial port of the microcontroller, the data sent by the serial port will be sent to the network immediately, and the data received by the network will also be sent to the microcontroller through the serial port.
Features
The network parameters, serial port parameters, login password, etc. can be configured through the embedded Web server.
The web server supports password login to prevent arbitrary modification.
Support cross-gateway: It can connect the serial server to any host with public IP on the Internet.
Support 1200 ~ 115200 baud rate.
Support 9-bit data transmission function: The 9th bit can be None, Odd Check, Even Check, 1, 0. Five ways are convenient to distinguish data frame and address frame in 485 communication.
The ZLVirCom configuration tool can automatically find the NETCOM device networking server on the network.
Virtual serial ports are supported.
Support data write protection to prevent random tampering.
Support default configuration startup.
LINK pin connection indication.
Hardware flow control CTS/RTS.
1KV network surge protection.
