Signal Wiring for Serial Interface
Each differential signal should be connected to a corresponding twisted pair as follows:
Note: NC - No Connect
Shield Termination
The customer's cable shield must be in 360° contact with the connector shroud and the
connector shell to provide complete shielding.
The connector shell should be metal with conductive surfaces. Suggested metal
connector shells for use with Mercury II encoders: AMP 748676-1 or equivalent; where
the dash number is dependent on the customer's outside cable diameter.
Terminate the shield as illustrated in the following diagram.
Note: Fold braided shield back over jacket. Example shows double-shielded cable. Dimensions
shown are for purpose of illustration only.
