Host interrupt
(Factory setting: IRQ5, G closed)
The header connector, shown in Figure 2-3 below, lets you connect the onboard
control logic interrupt outputs to one of the interrupt channels available on the host
computer XT/AT bus.
Fig. 2-3 Interrupt jumpers from left to right: IRQ 2,3,4,5,7,10,11,12,14,15 and G
Note: The GPS140HR hardware supports interrupt sharing! Jumper G must be closed on
one module per used interrupt. For example if two boards share interrupt number 7
only one board may have the G jumper closed. The G jumper connects a 1KOhm
resistor to ground while the shared interrupts are 3-stated pulling the line to an
inactive level.
