The TCR180PEX receives IRIG-A/B, IEEE 1344, IEEE C37.118 or AFNOR NF S87-500 time codes and can be used for synchronizing the system time of its host PC. The output of this card can generate an IRIG signal for other IRIG time code readers. The output format is independent from the incoming IRIG signal - a perfect solution to your IRIG conversion requirements.

It is used in applications like data acquisition, standalone computer time synchronization (for systems without a network connection or higher accuracy requirements) or as an IRIG converter device.

Receiver:
The module provides two input channels for decoding of modulated and unmodulated time codes in IRIG-A/B, IEEE 1344, IEEE C37.118 or AFNOR NF S87-500 format. The receiver's automatic gain control (AGC) allows the reception of modulated IRIG signals within an amplitude range from 600 mV_pp to 8 V_pp. In addition, the TCR180PEX provides an optocoupler input for decoding unmodulated codes with TTL- or RS-422 level for example. The board can be delivered with an optical input for unmodulated codes optionally.

Generator:
the board TCR180PEX can generate time codes in IRIG-A/B, IEEE 1344, IEEE C37.118 or AFNOR NF S87-500 format. These signals are provided as modulated (3 V_pp / 1 V_pp into 50 ohm) and unmodulated (TTL into 50 ohm and RS-422) time codes. An optical output for unmodulated codes is available on request.
