time or 32 parallel user bit outputs. 4U BMM unsupported
card. DD 1977. DDMI 7.401(77). DDHB 7.235(77).
Matrix Remote Control Decoder. This equipment is to be
used for the decoding of data from the CD2L/516, to
primarily control the selection of 25 cross points on a
vision matrix. DD 1977. DDMI 8.613(79). DDHB 8.359(79).
Serial Data Decoder. This card has been designed to decode
a serial data input as generated from either the CD2L/516
or CD2L/518. There are two serial data inputs:- balanced
line or modulated data from a carrier system. The decoder
checks for various errors in the serial data stream and
outputs parallel data to the Matrix interface card. The
Serial Data Decoder CD3/534 and Matrix interface card
UN23/653 together with a Mother card form the CD3L/531
