Remote Control via the IEC/IEEE-488.2 GPIB Interface
The instrument is equipped with an IEC-Bus connection. The connector according to
IEEE 488 is located at the rear panel of the instrument. This interface can be used to
connect a controller for remote control purposes. The connection must be made using
a shielded cable.
Characteristics of the IEC/IEEE.2 GPIB interface:

8 bit parallel data transfer

Bidirectional data transfer

Three wire handshake

High data transfer rate

Up to 15 instruments can be connected

Maximum length of interconnection cables 15 m (each single connection 2 m)

Figure 7: Pin assignment of IEEE connector
On power on, the amplifier is always in the local state (manual operation). At the front
panel display LOCAL will be indicated.
If a controller addresses the amplifier as a listener by sending the REMOTE
command, the amplifier changes to the remote state and remains in this state even
after termination of data transmission. This is indicated by the message GPIB at the
front panel display.
A change of the control mode is only possible when the amplifier is in STANDBY
mode.
