The XP2 connector is not pin compatible with the P2 connector on the ACR1505. This is because the ACR1505 has differential stepper outputs and the watchdog relay.

Important!: Single-ended encoders are not recommended mode of operation. Noise immunity is significantly reduced.

Note: DXP2 is a standard 40-pin female D-plug. XP2 is a 40-pin shrouded male header.
