CHAPTER 2. INSTALLATION
2.1. Initial Inspection
Inside the shipping container, you should find this operating manual and the
PCL-725 card.
The PCL-725 was carefully inspected both mechanically and electrically before
shipment. It should be free of marks and scratches and in perfect electrical order
on receipt.
Remove the PCL-725 interface card from its protective packaging by grasping
the metal rear panel. Keep the anti-vibration package since it may be used to
return the card if it needs repair. The package may also be used if the card is
stored outside of the computer.
The board should be handled only by the edges. The integrated circuits on the
board can be damaged by static electric discharge.
2.2. Base Address Selection
Most of the peripheral devices and the interface adapters in the PC are
controlled and sensed using the digital input and output ports. These ports are
addressed using the I/O port address space of the 8088 or 80286 microcomputer.
The I/O port base address for the PCL-725 is selectable by an 8 position DIP
switch. Valid addresses are from hex 200 to hex 3FE. Refer to Figure 2.1 for the
location of the DIP switch (SW1).
