Note:
IRQ4 can only be used for the data acquisition circuit if it is not already used for COM3.
It is possible to set up all three circuits to share either IRQ4 or IRQ5. However, only one device can use the
shared IRQ at a time; the ability for all three devices to run simultaneously is not supported.
Configure the IRQ options as shown in the following jumper settings.
