TCR180USB:
IRIG Time Code Reader for the Universal Serial Bus (USB)

Key Features:

• Universal Serial Bus (USB 2.0)
• Receiver status LEDs
• Buffered Real Time Clock
• Powered by USB (no extra power supply required)
• Signal input connectors for IRIG AM and IRIG DCLS
• Compact soft case

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 synchronization of computers where no serial interface or PCI slot is available. It is also suitable for checking time code outputs.

The TCR180USB provides a professional solution to your time synchronization requirements in mobile applications like field data acquisition with a laptop/notebook and can be deployed whenever you need to synchronize 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 is galvanically isolated from the signal input via an integrated optocoupler.
