Sender I/O Interface 'Cl. Decodes ~P address bus signals
to provide data outputs on relay contacts and data inputs
through opto-couplers. Relay contacts and rear connections
arranged to suit the control circuits of HF senders and the
Array mode selection of selected aerials. Power
requirements +5V. CH1/64J. DD 1980.
ender I/O Interface 'D'. Decodes ~P address signals to
provide data outputs on relay contacts and data inputs
through opto-couplers, or TTL logic circuits. Provides
Alarm-Standby c/o facilities and accepts frequency
measurement data in multiplexed BCD code. Power
requirements +5V. CH1/64J. DD 1980.
Code Converter. Interfaces to a Hewlett-Packard Frequency
Synthesiser, with IEEE 488 (HPIB) Bus interface, with input
and code conversion facilities so that the combination can
be driven from an automatic control system. A LED display
of frequency is given on the front panel so that this unit
can also be used as an indicator for use with manually
toned synthesisers.
Power requirements Mains 240V.
2U
Case Bay Mounted (Elma Case). Sub-unit UN26/40. DD 1980.
Data Interleaver. The unit uses an intel 8085 micro-
processor to interleave up to 4 serial data inputs from
automatic fault reporters into a single serial data output
for
further transmission to monitoring centres.
Power
requirements 5 volts DC approx. 1 Amp. CH1!63B (Chassis
fof CH1/63 with 'A' width front panel as on CH1/12A).
Parent equipment TM1M/1A or TM1M/1C. DD 1980. DDMI
2.461(83). DDHB 2.482(83). DDHB 2.482(83).
IEEE - 488 Interface. Interface unit to implement the
IEEE - 488 (HPIB) interface on the ZEUS Z80 microcomputer
system. Supports Talker, Listener and Controller functions
to IEEE std. 488-1978. ZEUS bus compatible on W-side of
edge connector. Power requirements +5v. CH1/64J. Parent
equipment PA6/108. DD 1981.
Time Code Converter. Used to convert the output of an
Ampex AVR2 Timer to EBU Time Code. Time Code frame rate
follows the timer output rate. The Converter will fit into
the AVR2 timer crate in place of the Ampex character gener-
ator. Power requirements from Ampex AVR2 Timer. PCB 170mm
x 230mm. DD 1982.
Sender I/O Interface E. Decodes ZEUS microprocessor bus
signals to provide data outputs on relay contacts and data
inputs through opto-couplers. Relay contacts and opto-
couplers share common rear connections to suit array mode
selection at HF transmitting stations. Power requirements
+5V. 4U unsupported card with J width front panel. Parent
equipment PA6/141 HF Sender Controller. DD 1982.
Subtitle Converter. This unit transcodes subtitle data
from American caption disks onto BBC title disks (Program
6). Power requirements 240V AC 4A max. 19" Rack Mounting,
3U+4U depth (max) 38Omm. Sub-units RD3M/1A, UN23/148. DD
1982.
