CSO Interface Unit. This unit is used with the New CSO
modifications to the Studio Mixer EP5/5l2. _It acts as an
interface unit between the New CSO mixer logic UN23L/635
and a 10 x 1 Michael Cox Electronics RGB switching matrix
which requires a TTL logic level to switch on a crosspoint.
CHl/64J. DD 1977.
Waveform Generator Logic Unit. Contains logic to enable
the GE6/540 to generate video 3-tone test signal and single
phase colour bars and to switch off the generator output
replacing it with a 750hm termination. Connects to the
GE6/540 by a 56-pole connector. Power requirements +5V.

Matrix Interface. This card accepts the parallel data from
the CD3/534 Serial Data Decoder and provides outputs to
control 25 cross points on a vision matrix. The card also
has an input of mixed synchronising pulses and generates
picture rate pulses which control the switching time when
changing source cross point selections. This card together
with the CD3/534 'Serial Data Decoder' and Mother card from
the CD3L/531 'Matrix Remote Decoder'. Power requirements
