Chapter 2 – EXPAXIS – 17 –
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.
