4.7.2 Input and Output Ｈ／Ｗ Recommended Connecting Circuit
All enFORCE inputs and outputs are active true low. All interface devices must
accommodate active true low connection (NPN) for correct operation.
When an input card with high input resistance is used, it may not normally receive OUT
DATA signals depending on the external environment and other conditions.
Note that when Mitsubishi I/O composite cards #A1SH42 and #A1Sx42 are used, the
above mentioned trouble may occur.
