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.
JP2 The JP2 configuration enables (or disables) the parallel port. Enabled is the default.
JP3 The JP3 configuration enables (or disables) the serial port. Enabled is the default.
JP4 JP4’s configuration determines the serial port (COM port) used. COM1 is the default. The COM port that
designates WBK21 depends on two factors: (1) WBK21 configuration, and (2) other installed devices
making use of COM ports.
JP4 Configurations for Serial Port Selection
JP5 In reference to the following figure, the top four jumper positions on JP5 select the serial port IRQ level.
IRQ4 is the default setting. The bottom two jumper rows select the parallel port IRQ level. IRQ7 is the
default parallel port setting. Note that COM and LPT ports cannot both be configured for IRQ5 at the same
time.

After WBK21 is properly configured, power-off your computer and install WBK21 into an available 16-bit
ISA bus. Consult your PC user’s manual as needed.
After WBK21 has been physically installed, power up your PC.
