Instruction Manual

● Make sure to turn off the power to the Touch before wiring each interface.

● Always use ferrules when wiring stranded wire and multiple wires to the terminal block.

Otherwise there is a risk of wires becoming disconnected.

4.1 Serial Interface (Port)

<Note>

The Touch is not equipped with terminating resistance. When using the RS422/485

interface, insert terminating resistance with the appropriate value (around 100 to 120 )

between terminal No. 8 (RDA) and terminal No. 9 (RDB) as required.
