Output

Circuit

When the device is located at the end of a transmission line via twisted-pair cable,

(when there is no cross-wiring), close across the terminal T2 –T3 with the attached

jumper pin (or with a leadwire).

When the device is not at the end, remove the jumper pin.

Remark 1: This device is not designed to cancel noise included in the input signals.

Be careful to eliminate such noise by using shielded cables.

Remark 2: Be sure to maintain the same potential at all the common negative

terminals for DC input.
