FUNCTIONAL DIAGRAM
CONNECTOR PINOUTS
The Texmate Model DI-45U TIGER CUB comes standard with
screw terminal block connections.
PIN DESCRIPTIONS
Pins 1 to 6 - Input Module. See the individual data sheet of the
input module selected for detailed information these pins or
pages 13-15 of this document. Usually Pin 1 is the Signal Input
High pin and Pin 3 is the Signal Input Low pin.
Pin 8 - Program Lock. By connecting this pin to the Common
Pin 11, the set up program is locked out. The programmed
meter parameters may be viewed but not changed, when the
meter is in the "locked out" mode.
Pin 9 - Hold Reading. When this pin is connected to the
Common Pin 11, the reading displayed will be frozen. A/D conver-
sions will continue however, and as soon as Pin 9 is disconnected
from Pin 11 the updated reading will be instantly displayed.
Pin 10 - Display Test. When this pin is momentarily connected
to the Common Pin 11, all segments of the display light up and
five 8's are displayed for 3 seconds. This detects any missing
segments in the display. The microprocessor is also reset dur-
ing the 3 seconds.
Pin 11 - Common. To activate, Hold, Test, Lockout or Reset, the
respective pins have to be connected to this Common Pin.
Pin 14 & 15 - AC Power Input. These pins are the power input
pins of the meter. The standard DI-45U TIGER CUB is precon-
figured for 100/120VAC for meters sold in North America. To
reconfigure for 200/240VAC operation, remove the meter from
the case and pull out the AC Power Voltage Selector located
directly behind the transformer on the printed circuit board. Turn
the AC Power Voltage Selector around and reinsert it into the
socket so that "200/240VAC" is visable. See the Component
Layout on page 10.
Chassis Ground Tab - This grounding tab is supplied for chas-
sis grounding.
POWER SUPPLY
The standard power supply for the DI-45U TIGER CUB is 100
to 120VAC or 200 to 240VAC, user selectable. See the Pin Out
Descriptions for Pins 14 and 15 for more details.
