Note 1 When this signal is held to ground, it is regarded as LOW. When this signal is open, it is regarded as HIGH. It can be driven by open collector driver.

Do not pull up this signal.

Note 2 The MATED2 signal is tied to ground, and the MATED1 signal is pulled up to HIGH level in the drive. When the drive detects the MATED1 signal is held to LOW, the drive regards the connection has completed. When the drive detects the MATED1 signal is held to HIGH, it regards the connection is incomplete.
