  • Page 25: Serial Port Operation Modes

    Serial Port Operation Modes In this chapter, we describe the various operation modes of the CN2600. CN2600 modes are grouped by type of application, such as Device Control or Reverse Terminal. The options include an operation mode that relies on a driver installed on the host computer, and operation modes that rely on TCP/IP socket programming concepts.

  • Page 26: Overview

    CN2600 Series Serial Port Operation Modes Overview The CN2600 network-enables traditional serial (RS-232/422/485) devices. The serial device server is a special-purpose computer equipped with a CPU and TCP/IP protocols that can bi-directionally translate data between the serial and Ethernet formats. Your own computer will be able to access, manage, and configure remote facilities and equipment over the Internet from anywhere in the world.

  • Page 27: Rfc2217 Mode

    CN2600 Series Serial Port Operation Modes ATTENTION Real COM mode allows several hosts to have access control over the same CN2600. The drivers that come with your CN2600 control host access by checking the host’s IP address. Please refer to the Accessible IP List section in Chapter 8, System Management Settings, for more details.

  • Page 28: Udp Mode

    CN2600 Series Serial Port Operation Modes UDP Mode Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can unicast or multi-unicast data from a serial device to one or multiple host computers and the serial device can receive data from one or multiple host computers.

  • Page 29: Dual-Host Redundant Data Acquisition System (Drdas)

    CN2600 Series Serial Port Operation Modes Dual-host Redundant Data Acquisition System (DRDAS) The DRDAS operation mode provides a highly redundant network structure that takes advantage of the CN2600’s dual LAN ports, dual IP addresses, and dual MAC addresses. DRDAS uses a backup PC that is set up to take over when the primary PC fails.

  • Page 30: Terminal Applications

    CN2600 Series Serial Port Operation Modes Terminal Applications Terminal applications involve connecting terminals to UNIX or Windows servers over a network. A terminal connects to the appropriately configured serial port the CN2600, and the CN2600 transmits information to and from a UNIX or Windows server over the network through its Ethernet port. You may need to check with your network administrator to determine the appropriate terminal mode.

  • Page 31: Reverse Terminal Applications

    CN2600 Series Serial Port Operation Modes Reverse Terminal Applications Reverse terminal applications are similar to terminal applications in that they involve using the CN2600 to manage the connection between a terminal and a server. The difference is that with reverse terminal applications, the terminal is connected through the network and the server is connected through the serial port, rather than the other way around.
