326 VT1422A Command Reference Chapter 7
ROUTe
•Returned Value: Data type is an int16 array). Use ROUT:SEQ:POINTS? to
determine how many values will be returned in the array. Can also be returned
as type string, see later comment regarding VXIplug&play function.
When the <type> parameter is "AIN," "AOUT," "DIN," or "DOUT," each value
returned represents a channel number.
When the <type> parameter is "DEST", each value returned is the data
destination code for a channel in the "AIN" list. The destination codes are:
1 = Reading will be sent to CVT only
2 = Reading will be sent to FIFO only
3 = Reading will be sent to CVT and FIFO
0 = Reading will be taken but not recorded (neither CVT or FIFO)
-1 = Channel is referenced in algorithm. Algorithm specifies destination.
•*RST Condition: To supply the necessary time delay before Digital inputs are
read, the analog input (AIN) scan list contains two entries for channel 0
(100).This minimum delay is maintained by replacing these default channels as
others are defined by algorithms or ROUT:SEQ:DEF. The three other lists
contain no channels.
•Send with VXIplug&play Function: hpe1422_cmdString_q(...) to return a
string which is a comma-separated-list of values
Usage ROUT:SEQ:DEF? AIN query for analog input (Scan List)
sequence

ROUTe:SEQuence:POINts?

ROUTe:SEQuence:POINts? <type> returns the number of channels defined in the
selected channel list types.
Parameters

Comments •The channel list contents and sequence are determined by channel references in

the algorithms currently defined.
•The <type> parameter selects which channel list will be queried:
"AIN" selects the Analog Input list.
"AOUT" selects the Analog Output list.
"DIN" selects the Digital Input list.
"DOUT" selects the Digital Output list.
Note: "DEST" is not one of the choices because it is not a channel list type.
