    Understanding EKI-1351/1352 The EKI-1351/1352 is network-based, serial device server for connecting RS-232/422/485 devices, such as CNCs, PLCs, scales, and scanners, directly to a TCP/IP network. Once connected through EKI-1351/1352, serial device will be able to send and receive data on a network like any other network device. It extends tradi- tional COM ports of a PC with access over a TCP/IP network.

  • Page 13: Com Port Redirector (Virtual Com Port)

    PC. The Advantech redirector can create up to 255 virtual COM ports. Application on the host can open virtual COM port to access the serial device servers at the same time.

  • Page 14: Figure 2.3 Multi-Access Mode

    2.1.2.2 Multi-Access Mode (Shared COM port mode) Most of serial devices are connected directly and physically to the PC serial ports via a cable. The operation system, ex. Windows XP, provides the COM ports that user’s application can access, and control the serial device through the serial cable. This means that the serial device can be connected to one host and only one application on this host can handle input, output and control operation on this device.

    IP address and TCP port number of the network hosts which the EKI serial device server connect to using Advantech Serial Device Server Configuration Utility. After configuration, when EKI serial device server receives the data from serial port, the device server will employ the connection to hosts which are configured.

  • Page 16: Serial Tunneling Mode

    Two native serial devices can communicate over an Ethernet network without any intermediate host PC and software programming. Serial Tunneling is very simple to use. You can use Advantech Serial Device Server Configuration Utility to designate one serial port as the tunneling master and another serial device server port as the tunneling slave.

    3.3.3.2 RTS Threshold RTS Threshold is the frame size above that an RTS/CTS handshake will be per- formed before attempting to transmit. RTS/CTS ask for permission to transmit to reduce collisions, but add considerable overhead. Disabling RTS/CTS can reduce overhead and latency in WLANs where all stations are close together, but can increase collisions and degrade performance in WLANs where stations are far apart and unable to sense each other to avoid collisions.
