TCP IP network regardless of whether the devices are used locally or at a remote site The VPM 7704 is a modular IP based network device that allows you to expand the number of serial ports for a host computer on demand As long as your host computer supports the TCP IP protocol you won t be limited by the host computer s bus limitation such as ISA or PCI or lack of drivers for various operating systems In addition to providing socket access the VPM 7704 also comes with a Real COM TTY driver that transmits all serial signals intact This means that your existing COM TTY based software can be preserved without needing to invest in additional software Three different Socket Modes are available TCP Server TCP Client and UDP Server Client The main difference between the TCP and UDP protocols is that TCP guarantees delivery of data by requiring the recipient to send an acknowledgement to the sender UDP does not require this type of verification making it possible to offer speedier delivery UDP also allows multicasting of data to groups of IP addresses Real COM Mode The VPM 7704 comes equipped with COM drivers that work with Windows systems and also TTY drivers for Linux systems The driver establishes a transparent connection between host and serial device by mapping the IP Port of the VPM 7704 s serial port to a local COM TTY port on the host computer This operation mode also supports up to 4 simultaneous connections so that multiple
