4321 Count Down Timer
For presentations that start on a regular cycle, the 4321 provides an easy
method to automatically start the show, as well as to indicate to the wait-
ing public how long it will be before the next show starts.
The 4321 consists of two components: the control unit, and the display.
The control unit may be installed where most convenient, usually next to
the equipment to be started, while the display, with its two 4 inch high
digits, may be be mounted for optimal visibility to the public.
In operation, the control unit is preset with the desired intermission time.
When placed in run mode, the remote display will display the preset
time, and proceed to count down, in one minute increments, to zero.
When zero is reached, a relay in the control unit closes for one second.
This contact is used to activate show control equipment, such as DVD or
audio control units.
For venues with multiple entrances, multiple displays may be employed.
The display units are merely connected in parallel. The RS-485 data
transmission technique used, allows the displays to be hundreds of feet
apart if required.
Several modes of operation are available, set by DIP switches on the rear
panel.
