  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.

• Page 15: Tcp Server Mode

  This operation mode supports max.16 simultaneous connections for each serial port on EKI-152X series to one host or several hosts. You should configure the 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.

• Page 16: Serial Tunneling Mode

  UDP is used primarily for broadcasting messages over a network. In the UDP server mode, EKI-152X series access max. 8 hosts’ UDP message. In the UDP client mode, EKI serial device servers transmit UDP message to max. 16 hosts simultaneously.
