Description
Serial Device Server - RS232/485/422 to Ethernet - USR-TCP232-306
Ethernet to serial converters USR-TCP232-306 support both interfaces RS232 and RS485, but can only use one at one time. Simple configuration and easy to use.
● RS232/RS485/RS422 (not use simultaneously)
● Wide power supply 5-36v DC
● httpsD client mode, sends serial data in https format
● Support TCP server/client, UDP server/client,Virtual COM
Features
- Auto-MDI/MDIX, RJ45 port with 10/100Mbps
- Work mode: TCP Server, TCP Client, UDP Client, UDP Server, HTTP Client
- Baud rate of serial port can be configured from 600 bps to 230.4 Kbps, supports check bit of none, odd, even, mark and space
- Heartbeat package mechanism to ensure connection is reliable, put an end to dead link
- User-defined registration package mechanism, check connection status and use as custom packet header
- Supports RS232/RS485/RS422 port ( Can’t be used at one time)
- Under TCP Server Mode, the connection number with client can be randomly set from 1 to 16, default number is 4. IP has been connected can be shown according to connection with calculating send / receive data.
- When connection number reaches a maximum, the new connection is kicked off the old one can be configured by user
- Parameters can be configured by built-in web page, AT command, serial port protocol and network protocol. Setting protocol is available to integrate into user’s software.
- Supports TCP client short connection function, user-defined the disconnected time.
- Device restart if no data transmission or timeout. User-defined the restart time.
- If data buffer needs to clear configuration before TCP connection establishment
- Supports DHCP, automatically obtain an IP address and query IP address via serial setting protocol.
- The global unique MAC address, user-defined MAC address
- DNS function
- DNS server address can be defined
- Firmware can be upgraded by network
- Provide Virtual com software
- Restore factory setting through software or hardware
- Running across the gateway, switches or routers.
- Can work in LAN, also can work in the Internet
Note: This kit includes the AU power adapter and DB9 cable.

Function Diagram
Work mode
TCP Server
Ethernet to serial converters USR-TCP232-306 monitor the set port and wait for a TCP client connection.
Data from the serial device will transmit to all successfully-connected TCP Clients via USR-TCP232-306.
TCP client mode
Ethernet to serial converters USR-TCP232-306 will initiate TCP connection to the destination IP address that
configured by the user and USR-TCP232-306 will continuously try to reconnect if establishing TCP connection
unsuccessfully. If the USR-TCP232-306 establishes TCP connection to TCP Server successfully, it can
realize bidirectional data transparent transmission between TCP Server and the serial device.
UDP mode
Ethernet to serial converters USR-TCP232-306 will transmit serial data from serial device to target network device
by UDP connection. USR-TCP232-306 will listen to port and transmit all received data to serial device.
httpsD Client
Ethernet to serial converters USR-TCP232-306 supports https Client mode which can transmit serial data to
the https server in https format(GET/POST).
Virtual Com Software
Synchronous Baud Rate
Dynamically change baud rate, data bit, check bit and stop bit of USR-TCP232-306 via network command.
Serial & Network Heartbeat Packet
USR-TCP232-306 maintains the normal connection with the server by sending heartbeat packet regularly.
