:DELAY:PARAmeter 
Syntax  :DELAY:PARAmeter <secnum>,{ON|OFF},<time> 
:DELAY:PARAmeter? <firnum>,<timercount> 
Description  Set the delayer parameters of the specified groups. 
Query the delayer parameters of the specified groups.  
Parameter 
Name  Type  Range  Default 
<secnum>  Integer  0 to 2047  None 
{ON|OFF}  Bool  ON|OFF 
OFF (even group);   
ON (odd group) 
<time>  Integer  1 to 99999  1s 
<firnum>  Integer  0 to 2047  None 
<timercount>  Integer  1 to 2048  None 
Explanation    <secnum> is the group number of the delayer parameters; {ON|OFF} is the 
output state; <time> is the delay time. 
  <firnum> is the group number of the first group of delayer parameters to be 
queried; <timercount> is the total number of groups of delayer parameters to 
be queried.  
Return Format 
For example, #90000000151,ON,1;2,OFF,1; wherein, #90000 is the data block 
header; 00015
 is the number of bytes followed; 1,ON,1;2,OFF,1; are the delayer 
parameters returned. The format of each group of parameters is “number,output 
state,delay time”, multiple groups of return values are separated by semicolons and 
parameters of the same group are separated by commas.  
Example  :DELAY:PARA 1,ON,2   /*Set the state of the first group to ON and the time to 2s*/ 
:DELAY:PARA? 3,2     /*Query two groups of delayer parameters starting from the 
third group*/ 
/*The query returns #90000000153,ON,1;4,OFF,1;*/ 
 
:DELAY[:STATe] 
Syntax  :DELAY[:STATe] {ON|OFF} 
:DELAY[:STATe]? 
Description  Enable or disable the delay output function. 
Query the state of the delay output function.  
Parameter 
Name  Type  Range  Default 
{ON|OFF}  Bool  ON|OFF  OFF 
Explanation    Enabling the delayer will change the output state of the channel. Make sure 
that the devices connected to the power supply will not be affected before 
enabling the delayer.   
The delayer parameters cannot be modified when the delayer is enabled.  
Return Format  The query returns ON or OFF. 
Example  :DELAY ON /*Enable the delay output*/ 
:DELAY? /*Query the status of the delay output and the query returns ON*/
