Chapter 3: OPTION SELECTION

FILTER RESPONSE JUMPERS

Jumpers are used to select input filtering on a channel-by-channel basis. When jumper FLT0 is installed,
additional filtering is introduced for input bit 0, FLT1 for bit 1, etc.

JUMPER SELECTION

Bit Filtered

FLT-0

-1
-2
-3
-4
-5
-6
-7

IN0
IN1
IN2
IN3
IN4
IN5
IN6
IN7

This additional filtering provides a slower response as described previously and should be used when AC inputs
are applied.

INTERRUPTS

Select the desired interrupt level by installing a jumper at one of the locations marked IRQxx. An interrupt is
asserted by the board when an input data bit changes state if software enabled as previously described.
