Power Meter Remote Operation

Configuring the Remote Interface

Configuring the Remote Interface
This section describes how to configure the GPIB, RS232 and RS422
remote interfaces.
Interface election
You can choose to control the power meter remotely using either the GPIB,
RS232 or RS422 standard interfaces.
For information on selecting the remote interface manually from the front
panel, refer to the EPM-P Series Power Meters User's Guide.
To select the interface remotely use the:
• SYSTem:RINTerface command
To query the current remote interface selection use the:
• SYSTem:RINTerface? command
GPIB Address
Each device on the GPIB (IEEE-488) interface must have a unique
address. You can set the power meter's address to any value between 0
and 30. The address is set to 13 when the power meter is shipped from the
factory.
The address is stored in non-volatile memory, and does not change when
the power meter is switched off, or after a remote interface reset.
Your GPIB bus controller has its own address. Avoid using the bus
controller's address for any instrument on the interface bus.
Hewlett-Packard controllers generally use address 21.
For information on setting the GPIB address manually from the front
panel, refer to the EPM-P Series Power Meters User's Guide.
To set the GPIB address from the remote interface use the:
• SYSTem:COMMunicate:GPIB:ADDRess command.
To query the GPIB address from the remote interface use the;
• SYSTem:COMMunicate:GPIB:ADDRess? query.
