1. Introduction
PISO-ENCODER/300/600 has a 3-axis or 6-axis encoder counter. Each
axis has a 32-bit, true counter with maximum counting rate of 1MHz. The
Index reset resets by using a C+/C- channel, which will reset every
revolution. The hardware reset resets by an external pin (HR1 ~ HR6). The
HR1 ~ HR6 also can be a digital input. 8-channel digital outputs are also
provided. 2500Vrms photo couplers isolate the digital I/O. This board
provides DOS, windows 95 and windows NT drivers.

2. Pins assignment
The pins assignment of PISO-Encoder600(U) board is shown in the following figure.
The power source of every encoder channel is designed for the DC 5V power source of
host computer’s PCB. Therefore, do not connect those pins with other DC 5V external
power source. And the maximum current of each encoder power is 100mA. Besides,
user should apply external DC 24V power source across pins of EXT_VCC and
EXT_GND in order to use digital inputs and outputs provided in PISO-Encoder600(U)0.
Hence, the digital inputs and outputs of PISO-Encoder600(U) will work correctly based
on the commands in digital output register (section 2.2.3) and digital input register
(section 2.2.4). The detailed description of pins’ function for PISO-Encoder600(U) is
listed in Table 1.

3. System Block Diagram
The PISO-Encoder600(U) has a 6-axis encoder counter. And each axis has a 32-bit
true counter with maximum counting rate of 1MHz. It also offers three different types of
the counting mode, which are QUADRANT mode, CW_CCW mode, and PULSE_DIR
mode. User should choose the correct mode based on actual type of encoder.
Otherwise, the PISO-Encoder600(U) will not work properly. Besides,
PISOEncoder600(U) also provides 3 different functions of counter resetting mode
including register reset, index reset and hardware reset. The Index reset function is
used to reset encoder counter through using a C+/C- channel signal during every
revolution. The hardware reset function is adopted to reset encoder counter by a pre-
defined external signal pin, namely HR1~HR6. Furthermore, when PISO-Encoder600(U)
is not set on the hardware reset mode, the pins of HR1~HR6 can be open as digital
inputs. In addition, PISO-Encoder600(U) also offers 8 channels of digital output. Every
digital output and input (digital I/O) is photo-coupled isolated up to 2500Vrms. The
detailed function block diagram of PISO-Encoder600(U) is demonstrated and
summarized in the following figure.

4. Hardware address selection
The hardware address of PISO-Encoder600(U) board can be set as 0~15 by DIP switch
A0~A3 on the PISO-Encoder600(U) board, as shown in Figure 2. The factory hardware
address setting is Hex 00. If the default address of this card is used by other device,
user can change the setting to various base addresses. The addressing of PCI bus is
defined in Table 1. According to the hardware address setting, programmer should call
function ENC6_REGISTRATION(cardNo, address) to confirm with the hardware setting
in the beginning of the program. The more detailed description for function of
ENC6_REGISTRATION() will be presented in chapter 3.
