Chapter 3: Option Selection
The only selections necessary to setup
on the card are the card’s base address and the differential
(DIFF) / single-ended (SE) jumpers. All other features are setup via software
, except IRQ’s.
Interrupts are optional, and directed to levels #2 through #7, #10 through #12, and #15 by a jumper at
locations labeled IRQ2 through IRQ7, IRQ10 through IRQ12, and IRQ15.
For PCB Revision C1 and newer, the “Input Mode Select” for encoder output type has 3 jumpers per
channel, 1 each for A, B & Z (Index).
From the center jumper post to t
he “SE” position applies 1.4V to receiver low inputs.
From the center jumper post to t
he “DIFF” position applies 1KΩ Termination between high and
low inputs and completes open wire detection circuitry.
