Introduction of 2 ports RS232/485/422 Serial Device Server

ALL-SDS102 is a dual serial device server, which can realize transparent transmission between TCP/UDP data packet and RS232/RS485/RS422 interface. The device has unique functions such as network printing, Modbus multi-host polling and watchdog mechanism. ALL-SDS102 is based on ARM processor and internally integrated with TCP/IP protocol. The user can easily realize the networking of embedded devices.

Features of the 2 Ports RS232/485/422 Serial Device Server

• Two channel serial communication display: TX/RX
• Support DC adapter
• Supports UDP broadcast function

Simple Transparent transmission

Transparent transmission means that whatever is transmitted, our device plays the role of a channel and sends data to the destination unchanged. On-site monitoring devices send data to Serial Device Servers transparent data transmission terminal, the terminal CUP receives data via serial port and packet data.

Different parameterization methods

Software Settings

Download settings software, search related Serial Device Servers in the LAN through the serial port server IP, name, MAC address, or the version number. Then set the parameters you need, otherwise keep the default.
Web-page Settings

1. Open your browser and inter the default IP address of the Serial Device Servers.
2. Open the login page of Serial Server, Enter the user name and password (default admin).
3. After setting parameter, Click Save and Restart, then setting will take effect.

Serial AT commands Settings

User can set parameter by module itself without going through another computer to configure. This setting method is used in the following situation: user have to configure IP address and destination IP address on site. AT command can meet the demand. After MCU connects serial server module by TTL (UART), MCU can configure setting by AT command.

Application Field of 2 ports RS232/485/422 Serial Device Servers

• Industrial data transmission, industrial automation
• security and protection monitoring, public security
• Smart home, power control, environmental monitoring, intelligent agriculture
• Door check on work attendance system, POS system, rice selling system
• Building automation system, power monitoring, self-service banking system, telecom machine room monitoring

Work Modes

TCP Server

Serial to Ethernet servers ALL-SDS102x listens on the setting port and waits for a TCP client connection. The data which the serial ports sent out transparently transmit to all connected TCP clients via ALL-SDS102/102v2
