This instrument is equipped with an IEEE St'd 488-1978 24-pin GP-IB connector. Use a GP-IB
cable that conforms to this standard.
Connection Procedure
Connect the cable as shown below.
Notes on Connection
• 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 2.2.
• This instrument may not operate properly if this instrument is connected to the PC through
converters (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.
• On the WT310E and WT310EH, it is physically impossible to connect a GP-IB cable and a USB
cable at the same time.
