Remote display unit (TFD) displays current temperature or output
status of TF3 at remote place.
TFD cable is TFD-3: 3m, TFD-5: 5m.
Connect the phone-jack of remote display unit (TFD) to the data
loader port of TF3.
This unit is dedicated for TF3 Series and it does not directly
communicate with upper devices (PC, PLC, etc.)

If TFD communication with TF3 error occurs, TFD ashes display

component for 1 sec. Check the connection with TF3.

※

When connecting TFD to the data loader port of TF3, you cannot connect Autonics SCM-US (USB to Serial converter,
sold separately). for communication. Use SCM-US48I(USB to RS485 converter, sold separately), SCM-38I(RS232C to
RS485 converter, sold separately).
