• In direct IP connection, applications can communicate with IP SERIAL SERVER using TCP/IP or UDP/IP socket connection. The raw data in the IP packet will be transferred from and to IP SERIAL SERVER’ serial port.
  • In the virtual COM mode, the host connects to IP SERIAL SERVER through 10/100 Ethernet. The serial device is then connected to IP SERIAL SERVER.
  • Paired mode is also called serial tunneling. Two IP SERIAL SERVER are involved and they must be set to a client and server pair. The remote IP address of the client site must be the same as server’s IP address and IP address of the client site must pass server’s address filtering. Applications do not actually use virtual COM port. They use
  • The Heart Beat protocol connection provides a reliable communications connection in Virtual COM Port Mode or with Paired Connection Mode. This feature restores the connection if communications are temporarily lost at either end due to loss of power or Ethernet connection.

EJ-IP102C Transmitter KVM Specifications

The EJ-IP102C Transmitter KVM provides the serial device server for Windows hosts to control serial devices located virtually anywhere through a TCP/IP or UDP/IP Ethernet connection. The EJ-IP102C Transmitter KVM has the asynchronous serial port connection on one side, and a 10/100 Mbps Ethernet connection on the other side. It connects devices, such as CNC, weight scales, and scanners. Applications include industrial/factory automation, automatic warehouse control, and hospital/laboratory automation. The EJ-IP102C Transmitter KVM Windows driver is designed to control the IP SERIAL SERVER Ethernet devices. The driver installs a virtual COM on windows which maps the virtual COM port to the IP address of the IP SERIAL SERVER device across the network, enabling the Windows applications to access remote serial devices over Ethernet. IP SERIAL SERVER can function as a server or client for both TCP and UDP connection. The application scenarios are direct IP mode, virtual COM mode, and paired mode. In direct IP and virtual COM modes, IP SERIAL SERVER should only work as a server. When in the paired mode one IP SERIAL SERVER must set as a client and the other must set as a server in both TCP and UDP connection.
