programme sources and no feeders. Power requirements +5 v.
Parent equipment PA6M/97. Transmitter Dept. 1985.
Band II CIP Display. Mimic diagram display for slave
(lower) CIP showing two PCM-fed services without feeders.
Power requirements +5 V. Parent equipment PA6M/97.
Transmitter Dept. 1985.
Clock Display Unit. This receives multiplexed data from a
modified C04/3 which it them de-multiplexes and displays on
a ten digit numerical LED display. The five pairs of
digits correspond to the current clock time (day, month,
hour, minute and second). Four individual LED's indicate
status information. A l6-bit parallel 0 utput is provided
which is intended for feeding the time information to a
PDPll
computer.
Power
requirements +5 V at
lA typical.
Printed circuit board 305mm x l65mm. Parent equipment
GE7/7. DD 1978.
Timecode Display Unit. This unit provides an eight digit
display of Hours, Minutes, Seconds and Frames together with
::!:
sign.
The
digits
are
0.8"
high
and
the
display
is
intended for medium distance viewing. It i s contained in
a B size 4U BMM portable carrying case and consists of a
Timecode Decoder, a Display Unit and a power supply. 4U
BMM 'B' size carrying case. Sub-units CD3/530, CD3/29 and
PS2/187A. DD 1979. DDMI 7.279(80). DDHB 7.274(79). EDI
l0373(l)APR80. DDMI 7.481(81).
AGC Display Unit. Provides outputs to 2 sets of 3-digits
7-segment displays. These outputs are derived from ll-bit
BCD parallel inputs. Strobe pulses to output latches are
enabled by sensing indicator voltages through opto-
isolatiors. Power requirements +5V. 3U unsupported card
190mm long. DD 1979.
Lamp Drive Expander. Provides additional indicator L.E.D.
drive outputs 39-39. Requires 6 bit BCD input from
CD2/519. Power requirements +5V lOOmA. Parent equipment
CD2L/518. Sub-units UN23/656 and CD2/519. SC PD 1980.
MF CIP Display. Display panel showing mimic diagram of the
state of four MF transmitters. The panel also carries mute
switches to enable selected blocks of indications to be
muted. Versions available:
A: 4 services. Upper two 3 transmitter, parallel
Lower two 2 transmitter, changeover
Power requirements +5V. Parent equipment PA6M/97C. DD
1981.
AGC Display Unit. Provides outputs to 2 sets of 3-digit,
7-segment displays. These outputs are derived from 11-bit
BCD parallel inputs. Strobe pulses to output latches are
enabled by sensing indicator vo1tages through opto-
isolators. 4u version of UN12/8. Power requirements +5V.
CH1/64J. Parent equipment PA6/132. DD 1981.
AGC Display Unit. Provides output of 2 sets of 2-digit, 7-
segment displays. These outputs are derived from ll-bit
BCD parallel inputs. Strobe pulses to output latches are
enabled by sensing indicator vo1tages through opto-
