6.2.2 Before you think that trouble occurred
Are the terminating resistors of the communication cable connected?
• Terminating resistors (120 ohms) must always be connected to both ends of the communication
cable line. (In J.NET and J.STATION, short the TERM terminals with a jumper and thereby
connect to the 120-ohm internal resistor.)
