Chapter 1 Overview 1
1.1 Introduction The PCL-734 offers 32 isolated digital output channels on a PC add-on card. Its isolated output channels provide 2,500VDC of protection. Each I/O channel corresponds to a bit in a PC I/O port. This makes the PCL-734 very easy to program. 1.

Chapter 2 2 Hardware Installation
2.1 Installation This chapter gives users a package item checklist, proper instructions about unpacking and step-by-step procedures for both driver and card installation. 2.2 Initial Inspection We carefully inspected the PCL-734 both mechanically and electrically before shipment. It should be free of marks and in perfect order on receipt. As you unpack the PCL-734, check it for signs of shipping damage (damaged box, scratches, dents, etc.).
The PCL-734 card has one function switch and three jumper settings. The following sections tell how to configure the card. You may want to refer to the opposite page for help identifying card components. Chapter 2 2.3 Switch and Jumper Settings Hardware Installation Table 2.1: Connectors, Jumpers, and Switches Label CN1 CN2 SW1 Function Isolated output E.
2.4 Base Address selection (SW1) You control the PCL-734's operation by reading or writing data to the PC's I/O (input/ output) port addresses. The PCL-734 requires four consecutive address locations. Switch SW1 sets the card's base (beginning) address. Valid base addresses range from Hex 200 to Hex 3F0. Other devices in your system may, however, be using some of these addresses. We set the PCL-734 for a base address of Hex 300 at the factory.
Warning! TURN OFF your PC power supply whenever you install or remove the PCL-734 or connect and disconnect cables. 1. 4. 5. 6. 7. 8. 9. 9 PCL-734 User Manual Hardware Installation 2. 3. Turn the computer off. Turn the power off to any peripheral devices such as printers and monitors. Disconnect the power cord and any other cables from the back of the computer. Remove the system unit cover (refer to your user's guide chassis user's guide if necessary).

Chapter 3 3 Signal Connections
3.1 Overview Maintaining signal connections is one of the most important factors in ensuring that your application system is sending and receiving data correctly. A good signal connection can avoid unnecessary and costly damage to your PC and other hardware devices. This chapter provides useful information about how to connect input and output signals to the PCL-734 via the I/O connector. 3.2 Connector Pin Assignments The PCL-734 has a DB-37 connector accessible from the card bracket.
13 PCL-734 User Manual Signal Connections Each of isolated digital output channels come equipped with a MOSFET. Every eight output channels share common emitters and integral suppression diodes for inductive loads. activated by connecting PCOM to VDD. (Channels 0~7 use PCOM1. Channels 8~15 use PCOM2. Channels 16~23 use PCOM3. Channels 24~31 use PCOM4.) If the external voltage (5 to 40V) is connected to each isolated output channel (IDO) and its isolated digital output turns on (max.

Appendix A Register Format A
A.1 Register Format Programming the PCL-734 is extremely simple. Each output channel corresponds to a bit in the card's registers. To turn on an output channel you write a ‘‘1” to the corresponding bit. The card requires four I/O register addresses. The address of each register is specified as an offset from the card's base address. For example, BASE+0 is the card's base address and BASE+2 is the base address + two bytes. If the card's base address is 300h, the register's address is 302h.
