Spe Command - Racal Instruments 1256E Manual

*SPE Command

SCPI Command Basics 5-20
If <location> is specified, it must be in the range from 0 through
100. If <location> is not specified, the instrument state will be
saved into non-volatile memory location 100.
State 0 is recalled at power-up. The 1256 is shipped without any
data in state 0. This effectively tells the 1256 to open all relays
at power-up. This default may be overwritten by placing all relays
in the desired power-up state, and then executing the command
*SAV 0
In the manner indicated earlier, a separate SYSTEM:NVUPD
command must follow to actually update the non-volatile memory.
If new relay modules are added to the system after the *SAV 0
command has been executed, the new relay modules will not be
programmed at power-up. Also, if module addresses are changed
after the execution of the *SAV 0 command, the modules whose
addresses have changed will not be programmed.
In general, whenever new modules are added, or module
addresses are changed, then the *SAV 0 command should be
used to place the relays of the new modules into the desired
power-up state.
The status byte is returned to the controller in response to a Serial
Poll Enable (SPE) message.
The status byte carries the following information:
