(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.
