Timer
The timer display is mounted in the console’s overbridge, just
below the SOLO/EXT meter pair. It is controlled by four pushbutton
switches at the bottom of the VU/Oscillator module. Control functions
are as follows:
AUTO – enables timer restart functions from programmed input
modules (see Input chapter, “Timer Restart”)
S/S – Start/Stop
RESET - return to zero (if the timer is stopped when this button is
pressed it will hold at zero; if it was running it will reset to zero and
immediately begin counting up).
HOLD – freezes the timer display (the counter keeps on going);
when released the display catches up to the current count.
Timer restart, Stop/Start, Reset and Hold control pulses are also
paralleled out at the module’s lower DB-25 connector, allowing a
second (slave) timer to be controlled by the console (see VO-80 module
pinout drawing on page 7-5).
A printed circuit board load sheet and schematic for the timer may
be found in the technical drawings on pages 149 and 148 respectively.
