DESCRIPTION
The MDMU is a complete 6 digit Counter/Timer in a small panel or printed
circuit board mounted package. It is designed to operate from a 5 VDC power
supply. It has a 6 digit LCD, with 0.35" high digits, and 3 selectable decimal
points. In the timer modes, a flashing annunciator is supplied to indicate that the
signal input of the MDMU is active. The displays are available in positive image
reflective (black digits, reflective background) or negative image transmissive
(illuminated digits, dark background) with red or yellow/green backlighting.
The MDMU has four Mode Select and two Decimal Point Select inputs
available for determining the basic operation. In most applications, the MS and
DP inputs are hard wired to select the appropriate function (counter or timer)
and counter decimal point position.
The COUNTER mode is selected by setting the Mode select inputs to the
appropriate levels (Hardware selection). Decimal points may also be set using
the DP Inputs (Hardware selection).
The TIMER mode and range is selected by setting the Mode Select inputs to
the appropriate levels (Hardware selection). The timing range increments
available are 1 msec, 10 msec, 100 msec, 1 sec, 0.1 min, 1 min, 0.01 hr, 0.1 hr,
and 1 hr. The TIMER ACTIVE annunciator will flash at a 1 Hz rate when the
input to the timer is activated.
CAUTION
This device contains CMOS circuitry which requires special anti-static
handling to the same degree required by standard CMOS integrated
circuits. Units should be stored in the conductive package used to ship the
device. Containers should be opened and units handled only on a
conductive table top by personnel wearing wrist-strap grounding equipment.
These devices have the same protection circuits as standard CMOS devices
to prevent damage to inputs due to nominal over-voltage.
