FEATURES:
- It is multi-purpose digital counter for counting traffic, people (head counts), motor-car or any other objects.
- Power supply : 12VDC. With maximum 65mA.
- can be connected directly to big display not more than 9".
- Maximum count from 0-9999
- Can be set for counting up or counting down.
- Can preset the digit for resetting and restarting counting automatically and sending voltage to "OUT" point.
- Can be connected to other board and extended counting to more than 9999 digits.
- PCB dimensions : 4.49x2.46 inches.

How to use switch: - Switch S1 is used for changing the first digit of each 1 step. Push and hold this switch for 2 seconds, the display will be reset to "0000". - Switch S2 is used for changing the tenth digit of each 1 step. Push and hold this switch for 2 seconds, the circuit will save the number shown on the display. For first use the number will show when power supply is connected. - Switch S3 is used for changing the hundredth digit of each 1 step. Push and hold this switch 2 seconds, the display will show the time of send voltage at output point. But, push and hold this switch for 5 seconds, the circuit will save the time to be showing at display now (at display showing "1" = 0.5 second). - Switch S4 is used for changing the thousandth digit of each 1 step. Push and hold this switch for 1 second, the display will show the reset number for restart counting. But, push and hold this switch for 3 seconds, the circuit will save the reset number to be shown on the display. - Switch S5 is used for changing down the digit of each 1 step. - Switch S6 is used for changing up the digit of each 1 step.

**NOTE* How to set the output point (in PRESET mode): 1.Setting the time by switch S1 to S4 (1 step = 0.5 second). 2.Push and hold switch S3 approx. 5 seconds to save the time on the display to "SAVE". 3.If you want to see this time, you can push and hold switch S3 approx. 2 seconds. How to set the first number when connecting the power supply: 1.Setting the number by switch S1 to S4. 2.Push and hold switch S2 until the display shows "SAVE" to save the number. How to set the reset maximum numbers in PRESET mode:

1.Setting the number by switch S1 to S4.

2.Push and hold switch S4 approx. 5 second to save the number on the display to show "SAVE".

3.If you want to see this number, you can push and hold switch S4 approx. 1 seconds.

Connection: - CK/IN point is used for connecting the counting signal from sensor or other equipment. - OUT 12V and CARRY point are connected to second board for adding digits. - OUT point will send the voltage 5VDC when the circuit is counting to preset of counting with this voltage can be applied to trigger the other equipment.
