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.
