(3) Connection Example
The following diagram shows a connection example. Use an SN75ALS174 or MC3487 manufactured by
Texas Instruments Inc., or equivalent for the line driver.
 Line Driver Output
 represents twisted-pair wires.
 Open-collector Output
Set limit resistor R so the input current, i, falls between 7 mA to 15 mA.
 represents twisted-pair wires.

• Use a shielded cable for I/O signals and ground both ends of the shield.
• Connect the shield of the cable on the SERVOPACK side to the connector shell so
that the shield will be connected to the frame ground (FG) through the connector.
