sn3101.book Page 25 Monday, January 19, 2009 3:37 PM Chapter 5 Port Operating Modes Overview To cover a broad range of serial applications, the SN3101’s COM port supports several port operating modes. These include Virtual Modem, Serial Tunnel, Console Management, and Real COM Port modes, for device control sessions, plus TCP Server/Client, UDP, and Modbus modes for socket application purposes.
sn3101.book Page 26 Monday, January 19, 2009 3:37 PM SN3101 User Manual TCP Server / TCP Client TCP (Transmission Control Protocol) provides a reliable transport layer for transmitting serial data over the TCP protocol via socket programming. TCP Server (RAW TCP) In TCP Server (RAW TCP) mode, data transmission is bidirectional. In this mode, the host computer initiates contact with the SN3101 and requests a connection to its serial port.
sn3101.book Page 27 Monday, January 19, 2009 3:37 PM Chapter 5. Port Operating Modes UDP Mode UDP (User Datagram Protocol) Mode is faster and more efficient at communications than TCP. In UDP mode, communications are bilateral. A serial device can send data to, and receive data from, up to 16 host computers via the SN3101’s COM port.
sn3101.book Page 28 Monday, January 19, 2009 3:37 PM SN3101 User Manual Virtual Modem In Virtual Modem mode, the SN3101’s COM port emulates a modem. The port acts as if it were a real modem for communication with a remote server. This allows software designed to transmit data over a serial modem-to-modem link, to perform serial operations over a TCP/IP ethernet connection. In this mode, the SN3101 “dials into” the remote server’s IP specifying the appropriate port address for the transmission.
sn3101.book Page 29 Monday, January 19, 2009 3:37 PM Chapter 6 COM Port Management Overview After you log into the SN3101, the Main Screen appears (seeThe SN3101 Main Screen, page 12).
