NMEA Client

NMEA Client 1.1

Regenerate the NMEA Sentences received via TCP/IP and transmit them via Serial Port. Download
  • The NMEA Server and NMEA Client utilities provide a versatile means of sharing a single, Serial Port-connected NMEA-0183 source among several applications on one or more computers, using TCP/IP.
  • The NMEA Server transmits the NMEA Sentences it receives to as many as 16 clients, which can reside on the host computer or on a network of computers.
    A network can be any normal, wired or wireless (Wi-Fi) interconnection of Local Area or Wide Area machines.
  • The NMEA Client re-generates the NMEA format to drive any available Serial Port, Real or Virtual, on the target computer.
    A Virtual Serial Port is a software device that emulates a standard serial interface, where a physical DE9/DB25 connector is absent.
  • The NMEA Server contains a built-in client to extend an existing network created by an upstream server. (One server can drive up to 16 other servers.)
  • Both applications are fully compatible with Tallon, which can be configured as either a server or client.
  • Transmit the NMEA Sentences received to the
    user-selected Serial Port.
  • Operate as a TCP/IP Client connected to a
    user-selected Server IP Address and Port Number.
  • Several instances of NMEA Client can be
    run simultaneously, on one or more machines.
  • Drive any available Serial Port COM 1 to COM 256.
  • Use the NMEA standard bit rate 4800,
    or any other basic rate 300 to 115200.
  • Serial Ports can be real or virtual.
  • Software Null-Modem pairs can be used as virtual
    Serial Ports, connected back-to-back.
    Several are available, free, reliable
    and easy to use.
    Setup details are provided on the
    NMEA Server Help page.
  • Display local Host IP Address.
  • Display current Latitude, Longitude and GMT.
  • Indicate receipt of valid position Sentences
    RMC, GGA and GLL, and any other
    NMEA Sentence, OTH.
  • Connect and disconnect manually.
  • Re-connect automatically, upon
    start-up and after any network drop-outs.
  • Indicate status of TCP/IP and Serial connections.
  • All settings are saved and restored between
  • Note that the NMEA Client Help guide is
    built into the NMEA Server application.
  • A TCP/IP source of NMEA-0183 Sentences
    (such as Tallon, NMEA Server, etc)
  • A Local Area Network (wired or wireless).
  • A physical or virtual RS-232 Serial Port
  • Windows 2000, XP, Vista, 7, 8, 8.1, 10 (32-bit, 64-bit)
