S Power supply method
S Setting the transmission delay time
Be sure to switch OFF the power supply to both the NT30/30C and the B7A Inter-
face Unit before changing DIP switch settings.
A 24 VDC power supply for communication must be supplied to the B7A Inter-
face Unit and the B7A Unit. The connection method differs depending on the
method used to supply power to the Units.
When the setting for transmission delay time is for high-speed transmission, use
a shielded cable. If no shielded cable is used, the maximum transmission dis-
tance will be 10 m regardless of the method used to supply power.
Ground the shield. Do not ground it to the minus terminal of the power supply.
