	*1 Use the twisted pair cable for SDA/SDB and RDA/RDB.
	*2 Set the terminating resistor selector to "330					".
	*3 Set the terminating resistor setting switch of the GOT main unit to "Disable".
			1.4.3 Terminating resistors of GOT
*4		Connect a 330 terminating resistor to the GOT to be a terminal.
	*5 Make sure to ground a cable shield line by applying Class D Grounding.
