Connecting
Always turn both devices OFF when connecting and disconnecting an interface con-
nector. Otherwise, an electric shock accident may occur.
• To avoid damage to the instrument, do not short-circuit the terminal and do not input volt-
age to the terminal.
• If the connectors are not securely mated, operation may fail to meet specifications, and
damage could result.

To connect the instrument to a controller (DTE), use a crossover ca-
ble compatible with the connectors on both the instrument and the
controller.
The I/O connector is a DTE (Data Terminal Equipment) configuration.
This instrument uses only pins 2, 3, and 5. The other pins are uncon-
nected.
