Meinberg
IRIG Time Code Reader for the Universal Serial Bus (USB)
The TCR180USB-EL is a time code reader with USB interface for decoding modulated and unmodulated IRIG, AFNOR and IEEE time codes and is used for time Synchronisation of computers where no serial interface or PCI slot is available. It is also suitable for checking time code outputs.

| Further information |
The TCR180USB-EL provides a professional solution to your time Synchronisation requirements in mobile applications like field data acquisition with a laptop/notebook and can be deployed whenever you need to Synchronise a standalone PC, laptop or server when no PCI or serial port is available.
With this device a technician can check the quality and validity of an IRIG signal in the field, due to the compact package and simple cabling (only one USB connection for both power and data is required). With modulated codes, the time information is transmitted by modulating the amplitude of a sine wave carrier. Unmodulated IRIG codes transmit the time information by varying the width of pulses. The automatic gain control of the receiver for modulated codes allows the decoding of IRIG signals with an amplitude of the sine carrier of 800 mVpp to 8 Vpp The potential-free signal input via SMB connector has an impedance of 600 Ohm. The input for unmodulated or DCLS (DC Level Shift) time codes also has an SMB connector. The receiver circuit of the TCR180USB-EL is galvanically isolated from the signal input via an integrated optocoupler. The drivers package for Windows contains a time adjustment service which runs in the background and adjusts the Windows system time continuously and smoothly. A monitor program is also included which lets the user check the status of the device and the time adjustment service, and can be used to modify configurable parameters, if run with administrator rights. The driver packages for Linux and FreeBSD contain a kernel driver which allows the board to be used as a reference time source for the NTP daemon which is shipped with most Unix-like operating systems. This also turns the computer into an NTP time server which can also provide accurate time to NTP clients on the network. Some command line tools can be used to setup configurable parameters and monitor the status of the board. The Meinberg Single-Driver-Concept simplifies driver installation dramatically - there is only one driver who supports all Meinberg PCI and USB devices and if you use our free API to access your Meinberg timing device from within your own applications, you can use the same source code for both PCI and USB devices. |
