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. An explanation of the functions performed by the various operating

modes is provided in the sections that follow.

Console Management

In Console Management mode, multiple users can establish a Telnet or SSH

session to the SN3101 to manage a server or serial device connected to its

COM port. Users can log in using the browser Telnet function, a direct Telnet

session, SSH or PuTTY.

Note: Be sure that the Socket entry specified on the Network page corresponds

to the port that the device listens on. 5001 is the SN3101’s default

setting (see Network, page 16, and Socket, page 17).

Real COM Port

This mode is used in conjunction with a virtual COM port driver installed on

the remote users’s local computer. (See Chapter 8, Virtual Port Management

for virtual port management details.) When the SN3101’s COM port set to this

mode, the device connected to the port appears as if it were a device directly

connected to a COM port on the remote users’s local computer.

This mode is useful with devices such POS terminals, Bar Code Readers, Serial

printers, etc. since it allows you to use software that was written for pure serial

communication applications. It can be used with other Altusen management

products, such as the PN9108 Power Over the NET™.

The SN3101 comes with Real COM drivers for Windows systems and TTY

drivers for Linux systems. See Chapter 8, Virtual Port Management for

installation and operation details.

Note: Real COM Port mode supports the Direct Access function (see Direct

Access, page 46, for details).
