16 PCL-734 User's Manual

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

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. See Chapter 2 for information on setting the card's

base address.
