:SYSTem:COMMunicate:RS232:DATABit
Syntax :SYSTem:COMMunicate:RS232:DATABit {5|6|7|8}
:SYSTem:COMMunicate:RS232:DATABit?
Description Set the data bit of the RS232 interface.
Query the data bit of the RS232 interface.
Parameter Name Type Range Default
{5|6|7|8} Discrete 5|6|7|8 8
Return Format The query returns 5, 6, 7 or 8.
Example :SYST:COMM:RS232:DATAB 8 /*Set the data bit of the RS232 interface to 8*/
:SYST:COMM:RS232:DATAB? /*Query the data bit of the RS232 interface and the
query returns 8*/
:SYSTem:COMMunicate:RS232:FLOWCrl
Syntax :SYSTem:COMMunicate:RS232:FLOWCrl {ON|OFF}
:SYSTem:COMMunicate:RS232:FLOWCrl?
Description Enable or disable the hardware flow control.
Query the status of the hardware flow control.
Parameter Name Type Range Default
{ON|OFF} Bool ON|OFF OFF
Explanation This power supply uses RTS/CTS hardware flow control mode. The instrument
monitors the status of the CTS pin. When the status is "True", the instrument sends
data; when the status is "False", the instrument stops sending data. The instrument
sets the CTS pin to "False" when the input buffer area is almost full and sets the CTS
pin to "True" when the input buffer area is available again.
Return Format The query returns ON or OFF.
Example :SYST:COMM:RS232:FLOWC ON /*Enable the hardware flow control*/
:SYST:COMM:RS232:FLOWC? /*Query the status of the hardware flow control
and the query returns ON*/
:SYSTem:COMMunicate:RS232:PARItybit
Syntax :SYSTem:COMMunicate:RS232:PARItybit {NONE|ODD|EVEN}
:SYSTem:COMMunicate:RS232:PARItybit?
Description Set the parity mode.
Query the current parity mode.
Parameter Name Type Range Default
{NONE|ODD|EVEN} Discrete NONE|ODD|EVEN NONE
Explanation NONE, ODD and EVEN represent to set the parity mode to "None", "Odd" and
"Even" respectively.
Return Format The query returns NONE, ODD or EVEN.
Example :SYST:COMM:RS232:PARI ODD /*Set the parity mode to odd*/
:SYST:COMM:RS232:PARI? /*Query the current parity mode and the query
returns ODD*/
