Signal names of the balance side are the same as
the DTE side with TXD and RXD reversed.
*1 For use with some A&D products.
Do not connect the cables to other manufacturers’ products such as a PC and PLC.
Using the wrong connection cable may damage the device. Be sure to check the compatible cable.
