Audio Line Changeover Unit. This unit is capable of
simultaneously switching four audio line channels. Two
fault inputs per side are provided. The input and
operational configuration can be altered via an EPROM and
DIL headers. The unit can be made compatible with existing
Band 11 audio line changeovers. Power requirements +24V or
+24V, +5V. Chassis CH1/64J. Chassis extender CH1A/44.
Audio Line Changeover Unit. This unit is the same as the
SE2S/40 except for the front panel legend. (The word
'line' is replaced by the letter 'A', and the 'link' is
replaced by the letter 'B'). Power requirements +24Vdc,
+5Vdc (optional). CH1/64J. Chassis extender CH1A/44.
Video Relay Panel. 12 relays (with bases) mounted on bar
which is supported from sub-panel by 4 spacers. The sub-
panel is mounted on a general purpose panel.
connector is 20 pole Varicon plug. Video connectors are 18
