4863 returns its identification code as
four fields separated by commas. These
fields are: manufacturer, model, six-digit
serial number and hardware-firmware
version and date e.g. ICS Electronics,
4863, S/N 510123, Rev 00.00 Ver
98.05.18 Note: the IEEE-488.2 specifica-
tion states that the word 'model' may not
appear in the IDN message.
Causes the 4863 to generate the operation
complete message in the Standard Event
Status Register when all pending selected
4863 operations have been finished.
Places an ASCII character 1 into the 4863's
Output Queue when all pending selected
4863 operations have been finished.
Controls the automatic power-on clearing
of the SRE and ESE registers. *PSC 0
allows devices to restore the saved SRE
and ESE values and to assert SRQ upon
power turn-on. *PSC 1 enables the power-
on clear and disallows a SRQ at power
turn-on. The PSC commands save the
SRE and ESE values in the E
2
PROM
Querys the PSC flag value. A returned
value of 0 indicates the registers will re-
tain their saved values, a returned value of
1 indicates the registers will be cleared.
Restores the state of 4863 from a copy
stored in its E2PROM by *SAV com-
mand. *RCL 0 restores the power on
setting and pulses the Reset output signal.
<value> = 0
4863 restores its power-up state except
that the state of IEEE-488 interface is
unchanged, including: instrument address,
