12.1 Abstract of Time Code
The transmission of coded timing signals began to take on widespread importance in the early 1950´s. Espe-
cially the US missile and space programs were the forces behind the development of these time codes, which
were used for the correlation of data. The definition of time code formats was completely arbitrary and left to
the individual ideas of each design engineer. Hundreds of different time codes were formed, some of which were
standardized by the "Inter Range Instrumentation Group" (IRIG) in the early 60´s.
The TCR180 supports decoding and generating of IRIG-A, IRIG-B, IRIG-G, AFNOR NF S87-500, IEEE C37.118
and IEEE 1344.
