FIGURE A-2. INX — Initiate Op Code Command
FIGURE A-3. FTH — Fetch Command
Syntax: INX VOLT (initiate voltage reading)
INX CURR (initiate current reading)
Function: Commences a data acquisition process in accordance with the preceding FNC command.
Description: The response to the INX command is a dynamic time-out value, unless a catastrophic error condition
exists, in which case an error message will be returned. If the time-out value returned is not zero, this
indicates the power supply’s output voltage or current has not yet settled. A time delay should be
observed before proceeding with the FTH command, or the command may be repeated until a zero
value is returned, but the preceding FTH command must also be repeated.
Example: INX VOLT Power supply initiates voltage reading)
FTH VOLT Power supply sends voltage reading to controller)
INX
Syntax: FTH VOLT (fetch voltage reading)
FTH CURR (fetch current reading)
Function: Commands the previously designated power supply to return the requested data reading.
Description: This command must immediately follow an INX command. The value returned is the value of the out-
put voltage or current, whichever was requested, unless a catastrophic error condition exists, in which
case an error message will be returned. The value observed will be in scientific notation.
Example: INX VOLT Power supply initiates voltage reading)
FTH VOLT Power supply sends voltage reading to controller)
