When connecting a personal computer to the instrument via a communication interface, observe
the following:
GP-IB
The GP-IB connector of the GP-IB communication module is a 24-pin connector of IEEE Std
488-1978. Only use cables that conform to IEEE Std 488-1978 as a communication cable.
Connection Procedure
Connect the cable as shown in the figure below.

When connecting the cable, take note of the following.
To reduce noise, use two ferrite cores (e.g., ZCAT 3035-1330 from TDK) at both ends of the
interface cable as shown above.
Securely tighten the screws which fasten the GP-IB cable connector.
If more than one equipment is connected, the same addresses cannot be assigned to different
equipment.
Use only cables of 2 m or less to interconnect each equipment.
How to Assign an Address
The address can be assigned easily by turning the rotary dipswitch as shown in the figure below.
Any address can be set from 0 to 15; the characters A to F on the dipswitch correspond to
the address 10 to 15 respectively.
