UART to TCPIP Lan Ethernet Converter Module
SS_TCP01/02/03 Module

1．General Description
The SS-TCP embedded TCPIP to UART module is a kind of embedded protocol modules from TCP/IP to UART. It provides bidirectional transparent data transmission from the serial port to TCP/IP network. It transparently transmits the data received from the serial port to the data server on the network; the data from the server is transparently delivered to the serial port via the module.

The SS-TCP embedded serial module provides 100M/10M Ethernet interface upwards, and 1 to 3 standard TTL serial ports (UART1/UART2/UART3) among which the UART1 & UART2 are full-rate serial ports with a Baud rate of 1.2kbps~1.8432Mbps and the UART3 a low-rate serial port with a Baud rate of 1.2kbps~4.8kbps.
SS-TCP works in various network conditions. The parameters of the network and the serial port can be configured by a TCPManager program running in Windows, or by users program.
SS-TCP supports 4 operating modes:
• UDP (UDP mode)
It provides connectionless UDP communication;
• TCP server (TCP server mode)
The module monitors connection request at the designated serial port.
• TCP Client (TCP Client mode)
It initiatively requests connection when powered on.
• Virtual COM (virtual serial mode)
It operates the serial port managing software and produces virtual serial port through which the communication with the serial port device is conducted, as simple and convenient as operating the commom serial port.
Exchanging data with SS-TCP by means:
• Re-orienting the network data to the virtual serial port through the serial port managing software and reading the data from the virtual serial port, or
• Directedly using Socket to program.
