Overview
The SAM/DEC/008 decommutates IRIG-106 Ch.4 PCM streams and
provides a high-speed programming link for Acra KAM-500 systems. The
unit uses a single USB 2.0 connection in the ground station/programming
PC.
The PCM decommutator accepts either differential ended RS-422 inputs
or single ended TTL inputs. With BIØ-L codes only a single input is used.
For other line codes, an additional data clock (DCLK) line is required. Any
sync word up to 32 bits can be used to identify the start of a minor frame
(including mask and alternating patterns). The SAM/DEC/008 can be
configured with GS Works 8 or with custom APIs similar to those used
with the SAM/DEC/007.
The programming link can be used to program multiple Acra KAM-500s. A
bi-directional, differential ended (RS-422) pair of data lines (X-PROG) is
used to transmit or receive data at 1Mbps.
