Connection Precautions
• Be sure to tighten the screws on the GP-IB cable connector firmly.
• The instrument can be connected to more than one item of equipment (e.g. a
personal computer) if more than one GP-IB cable is used. However, it is not possible
to connect more than 15 items of equipment (including the controller) to a single bus.
• If you connect the instrument to more than one item of equipment, make sure that a
different address is used for each item.
• Each connecting cable must be 2 m or less in length.
• The total length of all the cables must not exceed 20 m.
• While communications are in progress, more than two-thirds of the connected
equipment items must be turned ON.
• When connecting more than one item of equipment, connect them so that the
connection route forms a star or linear configuration. Loop or parallel wiring is not allowed.
CAUTION
Be sure to switch off power to both your PC and the oscilloscope before
connecting or disconnecting cables. Failure to switch power off may cause
internal circuit failure or improper operation.
