: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
:SYST:COMM:RS232:DATAB?
: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
:SYST:COMM:RS232:FLOWC?
:SYSTem:COMMunicate:RS232:PARItybit
Syntax :SYSTem:COMMunicate:RS232:PARItybit {NONE|ODD|EVEN}
:SYSTem:COMMunicate:RS232:PARItybit?
Description Set the parity mode to “None”, “Odd” or “Even”.
Query the current parity mode.
Parameter
Name Type Range Default
{NONE|ODD|EVEN} Discrete NONE|ODD|EVEN NONE
Return Format The query returns NONE, ODD or EVEN.
Example :SYST:COMM:RS232:PARI ODD
:SYST:COMM:RS232:PARI?
