4807 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,
4807, S/N 510123, Rev. 03.10. The
IEEE-488.2 specification states that the
word 'model' may not appear in the IDN
message.
Causes the 4807 to generate the operation
complete message in the Standard Event
Status Register when all pending selected
4807 operations have been finished.
Places an ASCII character 1 into the 4807's
Output Queue when all pending selected
4807 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 saves the
488.2 SRE and ESE registers and the
SCPI transition and enable register val-
ues.
Quires 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 4807 from a copy
stored in its Flash by *SAV command.
*RCL 0 recalls saved configuration, up-
dates output levels and re-initializes the
UART. Allow the 4807 100 ms and the
2307 150 ms to complete the *RCL com-
mand.
