Page 8: Introduction
1. Introduction 1. Introduction Summary Before, the measurement and control was realized by way of inserting PCI interface boards into expansion slots of a desktop computer in case of configuring system using computers. However, because of the limit on number of expansion slots, it is difficult to configure system sometimes, or it is difficult to perform the same measure and control as PCI interface boards for a note PC. -

Page 27: Connection Method
3. Setup Connection Method When connecting this product to an external device, you can use the supplied connector plug. When wiring the Module, strip off approximately 7 - 8 mm of the covering for the cable, and insert the bare wire by pressing the orange button on the connector plug. - Page 28 3. Setup Connecting to a rotary encoder When the module is used with an external 5-V power supply, a current limiting resistor do not have to be inserted. When it is used with an external 12-V power supply, however, a resistor of about 400 ohms is required. Figure 3.5.

Page 29: Counting Function
3. Setup Counting Function The functions supported by this product is listed below. Because the count input multiplier and clear method can be set separately, the supported modes are as follows: single-phase input is of 1 mode, 2-phase input is of 6 modes, single-phase input with gate control is of 2 modes. - Page 30 3. Setup 2-phase input 2-phase pulse input refers to the input of two pulses, Phase-A (fast signal) and Phase-B (slow signal) that differ in phase by 90°. If phase-Z is provided (reference position signal), the counter can be cleared using 2-phase pulse input. Using rotary encoders and linear gauges, you can measure the moving distance.
- Page 31 3. Setup Setting rotary direction of the encoder DIR: count up in counterclockwise. The encoder count up in counterclockwise, so the counter data count down when the encoder turn in counterclockwise Phase-A (Phase-A/UP) Phase-B (Phase-B/DOWN) Phase-Z (Phase-Z/CLR) Count data FFFFFF FFFFFE FFFFFD 4 multiplier...
- Page 32 3. Setup Single-phase input with gate control The counter can be started/stopped according to the gate control signal that is input together with a string of single-phase pulses. The clear signal zero-clears the counter value. Because the pulses from an external signal can be measured in a segment of time, measuring the rotational velocity is practicable.
-
Page 33: Clearing Count Value
3. Setup Clearing Count Value Asynchronous clear The counter is zero-cleared when phase-Z is input, irrespective of the input state of phase-A or B. When phase-Z is set to positive logic, HIGH level is effective signal; When it is set to negative logic, LOW level is effective signal. - Page 34 3. Setup Point By the setting above, Phase-A and Phase-Z rise is detected within the module. First, check out phase-Z rise, clear the counter data at the next rise of phase-A. Even if the phase-Z input turns LOW before phase-A rises, the counter data will be cleared.
-
Page 35: Digital Filter
3. Setup Digital Filter According to the using environment, the Chattering Noise and Cross Talk may be presented in phase-A, B or Z of the counter. It would result in counting error. Use digital filter to avoid this abnormity. Digital filter clock setting data determines the sampling clock cycle for the digital filter. -
Page 36: Count-Match Output
3. Setup Count-match Output When there is a match between a count value on a channel and a count compare value, the pulse output is prepared to notify external device. The pulses width can be changed in the allowable range 0 - 104.45msec. -
