4899A returns its identification code as
four fields separated by commas. These
fields are: manufacturer, model, six-digit
serial number and hardware-firmware ver-
sion and date e.g. ICS Electronics, 4899A,
S/N 603001, Rev. 00.00, 06.03.02. The
IEEE-488.2 specification states that the
word 'model' may not appear in the IDN
message.
Causes the 4899A to generate the operation
complete message in the Standard Event
Status Register when all pending selected
4899A operations have been finished.
Places an ASCII character 1 into the
4899A's Output Queue when all pend-
ing selected 4899A operations have been
finished.
Controls the automatic power-on clearing
of the SRE and ESE registers. *PSC 0 al-
lows 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 values.
Querys the PSC flag value. A returned value
of 0 indicates the registers will retain their
saved values, a returned value of 1 indicates
the registers will be cleared.
Restores the state of 4899A from a copy
stored in its Flash by *SAV command.
*RCL 0 recalls saved configuration,
updates output levels and re-initializes
the UART. Allow the 4899A 100 ms and
the 2303 150 ms to complete the *RCL
command.
