Before installing the MBS-GPS Module, refer to Figure 1 for the location of various rotary

switches, connectors and jumpers.

Interrupt Selection Switches, SW4, SW8, SW12

The MBS-GPS uses simple and easy to use rotary switches for IRQ selection. Simply place the

serial port IRQ switch to the desired setting you want. If you select an invalid IRQ then inter-

rupts are disabled for that port. IRQ’s 3, 4, 5, 6, 7, 9, 10, 11, 12, 14 and 15 are supported. Thus

if you select IRQ 1, 2, 8, 13 there is no IRQ enabled for that port. The CPLD simply ignores

invalid selections. These can be used for polled mode operation.

Simply select the desired IRQ level by rotating the IRQ Selection switch the appropriate posi-

tion (see Figure 1).

Default conﬁguration shown in Figure 1 for SW4 is IRQ4 which is standard for COM1. Default

conﬁguration for SW8 is IRQ3 which is standard for COM 2. Each port must use a unique IRQ.

Caution

Improper IRQ conﬁguration can result in your CPU locking up due to an IRQ conﬂict. Most

COM libraries allow for non-standard IRQ settings as will after market drivers. Windows 95,

98, ME, NT, 2000 and XP may limit your IRQ selection without aftermarket drivers. This is

usually not required unless all IRQ’s supported by the OS are already allocated.
