Remote Programming
INTERFACE CONTROL COMMANDS
*RST The *RST command resets the SR430 to its default configurations. The
communications setup is not changed. All other modes and settings are
set to their default conditions and values.
*IDN? The *IDN? query returns the SR430's device identification string. This
string is in the format "Stanford_Research_Systems,SR430,s/
n00001,ver007". In this example, the serial number is 00001 and the
firmware version is 007.
LOCL i The LOCL command sets the RS232 local/remote function. If i=0 the
SR430 is LOCAL, if i=1 the SR430 will go REMOTE, and if i=2 the
SR430 will go into LOCAL LOCKOUT state. The states duplicate the
GPIB local/remote states. In the LOCAL state both command execution
and keyboard input are allowed. In the REMOTE state command execu-
tion is allowed but the keyboard and knob are locked out except for the
[HELP] key which returns the SR430 to the LOCAL state. In the LOCAL
LOCKOUT state all front panel operation is locked out, including the
[HELP] key.
STATUS REPORTING COMMANDS
The Status Byte definitions follow this section.
*CLS The *CLS command clears all status registers.
*ESE (?) {i} The *ESE i command sets the standard status byte enable register to the
decimal value i (0-255). The *ESE? command queries the value of the
status byte enable register.
*ESR? {i} The *ESR? query reads the value of the standard status byte. The value
is returned as a decimal number from 0 to 255. If the parameter i (0-7) is
included, the value of bit i is returned. Reading the entire byte will clear it
while reading bit i will clear just bit i.
*SRE (?) {i} The *SRE i command sets the serial poll enable register to the decimal
value i (0-255). The *SRE? command queries the value of the serial poll
enable register.
*STB? {i} The *STB? query reads the value of the serial poll byte. The value is re-
turned as a decimal number from 0 to 255. If the parameter i (0-7) is in-
cluded, the value of bit i is returned. Reading this byte has no effect on
its value.
*PSC (?) {i} The *PSC command sets the value of the power-on status clear bit. If i=1
the power-on status clear bit is set and all status registers and enable
registers are cleared on power up. If i=0 the bit is cleared and the status
enable registers maintain their values at power down. This allows the a
service request to be generated at power up.
ERRE (?) {i} The ERRE command sets the error status enable register to the decimal
value i (0-255). The ERRE? command queries the value of the error stat-
us enable register.
