Notes about Connections
• Firmly tighten the screws on the GP-IB cable connector.
• On the PC end, use a GP-IB board (or card) made by National Instruments. For details, see section

(such as a GP-IB to USB converter). For more details, contact your nearest YOKOGAWA dealer.
• Several cables can be used to connect multiple devices. However, no more than 15 devices,
including the controller, can be connected on a single bus.
• When connecting multiple devices, you must assign a unique address to each device.
• Use cables that are 2 m or shorter in length to connect devices.
• Make sure the total length of all cables does not exceed 20 m.
• When devices are communicating, have at least two-thirds of the devices on the bus turned on.
• To connect multiple devices, wire them in a daisy-chain or star configuration as shown below. You
can also mix these configurations. Loop configuration is not allowed.
