Power Meter Remote Operation
Configuring the Remote Interface
1-4 HP E4418B/E4419B Programming Guide
RS232/RS422 Configuration
The RS232/RS422 serial port on the rear panel is a nine pin D-type
connector configured as a DTE (Data Terminal Equipment). For pin-out
information and cable length restrictions refer to the HP
E4418A/E4419B User’s Guides.
You can set the baud rate, word length, parity, number of stop bits,
software and hardware pacing, either remotely or from the front panel.
For front panel operation refer to the HP E4418A/E4419B User’s Guides.
For remote operation use the following commands:
SYSTem:COMMunicate:SERial:CONTrol:DTR
SYSTem:COMMunicate:SERial:CONTrol:RTS
SYSTem:COMMunicate:SERial[:RECeive]:BAUD
SYSTem:COMMunicate:SERial[:RECeive]:BITs
SYSTem:COMMunicate:SERial[:RECeive]:PACE
SYSTem:COMMunicate:SERial[:RECeive]:PARity[:TYPE]
SYSTem:COMMunicate:SERial[:RECeive]:SBIT
SYSTem:COMMunicate:SERial:TRANsmit:BAUD
SYSTem:COMMunicate:SERial:TRANsmit:BIT
SYSTem:COMMunicate:SERial:TRANsmit:ECHO
SYSTem:COMMunicate:SERial:TRANsmit:PACE
SYSTem:COMMunicate:SERial:TRANsmit:PARity[:TYPE]
SYSTem:COMMunicate:SERial:TRANsmit:SBIT
Programming Language Selection
You can select one of two languages to program the power meter from the
remote interface. The language is SCPI when the power meter is shipped
from the factory. The other language depends on the model number of your
power meter:
• For E4418B the language is 437B programming language.
• For E4419B the language is 438A programming language.
The language selection is stored in non-volatile memory, and does not
change when power has been off, or after either a remote interface reset,
or a front panel preset.
For information on selecting the interface language manually from the
front panel, refer to the E4418B/E4419B User’s Guides.
To select the interface language from the remote interface use the:
