WARNING

Electrical Shock Hazard! Perform all hardware setups with all power off to the device

serviced and to all connected equipment; otherwise, personal injury may result.

WBK21 is used to link WaveBook to a desktop PC. WBK21 contains the following two ports:

• 2.5 Mbyte/second (enhanced parallel port), often referred to as an LPT printer port.

• 16550 type buffered, high-speed, serial port. Often referred to as serial communication, or

COM port.

WBK21 installs into an IBM compatible computer using any available 16-bit ISA bus backplane slot. Prior

to installing the card, make sure it is configured for your preferences. A discussion of card configuration

now follows.

WBK21 Jumper Settings

JP1

WBK21 occupies the I/O address space of one parallel printer port (LPT1, LPT2, or LPT3). The factory

default setting (via JP1) is LPT1 (&h378).

If an IBM Monochrome board is not installed, then WBK21 would be designated as LPT1 or LPT2.

If an IBM Monochrome display board (with an on-board parallel printer port) is installed in your PC, the

Monochrome printer port will always be designated LPT1 and have an address designation of &h03BC.

Other parallel printer ports (or WBK21s) are then designated as LPT2, or LPT3.
