R&S ESU Remote Control – Basics
Starting Remote Control
5.6 Operating Manual 1302.6163.12 - 03
Via GPIB:
CALL IBLOC(analyzer%)
'Set instrument to manual operation
5.4.3 Remote Control via RS-232-Interface
5.4.3.1 Setting the Transmission Parameters
To enable an error-free and correct data transmission, the parameters of the unit
and the controller should have the same setting.
Parameters can be manually changed in menu SETUP-GENERAL SETUP in table
COM PORT or via remote control using the following command:
SYST:COMM:SER:
…
The transmission parameters of the COM interface are factory-set to the following
values:
baudrate = 9600, data bits = 8, stop bits = 1, parity = NONE and owner =
INSTRUMENT.
For remote control, the interface should be allocated to the operating system (owner
= OS) so that the control characters including @ can be recognized by the interface.
Manually:
Setting the COM interface
1. Call SETUP-GENERAL SETUP menu
2. Select desired baudrate, bits, stopbit, parity in table COM PORT.
3. Set owner to OS in table COM PORT.
4. Terminate input using the ENTER key.
5.4.3.2 Return to Manual Operation
Return to manual operation is possible via the front panel or via RS-232 interface.
Manually:
Press the LOCAL softkey or the PRESET key.
• Before the transition, command processing must be completed as otherwise
transition to GPIB is performed immediately.
• The keys can be disabled by the universal command LLO (see chapter
“Maintenance and Instrument Interfaces” , section “Interface Messages” on
page 8.4 ) in order to prevent unintentional transition. In this case, transition to
manual operation is only possible via GPIB.
• The keys can be enabled again by deactivating the REN line of the GPIB (see
chapter “Maintenance and Instrument Interfaces” , section “Bus Lines” on
page 8.3 ).
