4.2 Optocoupler input
The optocoupler on terminal strips X6 (input IN2), X7 (IN3) and X8 (IN4) are galvanically isolated
from the Reader electronics and must therefore be powered externally. The external voltage may
however be provided by the card. All 3 inputs are identical and may therefore be configured
individually.
