SYNTAX: ++read_tmo_ms <time> where <time> is decimal value between 1 and
3000
MODES AVAILABLE: CONTROLLER
8.14. rst
This command performs a power-on reset of the controller. The process takes about 5
seconds. All input received over USB during this time are ignored.
SYNTAX: ++rst
MODES AVAILABLE: CONTROLLER, DEVICE
8.15. savecfg
This command enables, or disables, automatic saving of configuration parameters in
EPROM. If enabled, the following configuration parameters are saved whenever they are
updated – mode, addr, auto, eoi, eos, eot_enable, eot_char and read_tmo_ms.
However, frequent updates may eventually wear out the EPROM. This command may
be used to temporarily disable automatic saving of configuration parameters to reduce
EEPROM wear.
The savecfg setting itself is not saved in EPROM. It is always enabled on startup (after
power up, or reset).
SYNTAX: ++savecfg [0|1]
MODES AVAILABLE: CONTROLLER, DEVICE
EXAMPLE:
++savecfg 1 Enable saving of configuration parameters in EPROM
++savecfg 0 Disable saving of configuration parameters in EPROM
++savecfg Query current setting
NOTE:
“++savecfg 1” command will immediately save the current values of all configuration
parameters, in addition to enabling the automatic saving of parameters.
8.16. spoll
This command performs a serial poll of the instrument at the specified address. If no
address is specified then this command serial polls the currently addressed instrument (as
set by a previous ++addr command). This command uses the time-out value specified
by the read_tmo_ms command.
