:SYSTem:COMMunicate:GPIB
The commands to check the IEC bus are under this node (GPIB = General P
urpose Interface
Bus)
:SYSTem:COMMunicate:GPIB[:SELF]:ADDRess 1 to 30
The command sets the IEC bus instrument address. *RST value is 28
Example: :SYST:COMM:GPIB:ADDR 1
:SYSTem:COMMunicate:SERial
The command to set the serial interface are under this node. The data format is fixedly set to 8
data bits, no parity and 1 stop bit. These values cannot be changed. The device represents a DTE
(Data Terminal Equipment) in relation to the serial interface. Therefore the the controller must be
connected via a 0-modem.
:SYSTem:COMMunicate:SERial:BAUD 1200| 2400| 4800| 9600| 19200| 38400| 57600| 115200
The commands sets the baud rate for both the transmit and the receive direction. *RST has no
influnence on this parameter.
Example: :SYST:COMM:SER:BAUD 1200 *RST value is 9600
:SYSTem:COMMunicate:SERial:CONTrol:RTS ON | IBFull | RFR
he commands sets the hardware handshake. *RST has no influence on this parameter.
ON Interface line RTS is always active.
IBFull | RFR Input B
uffer Full | Ready For Receiving.
Interface line RTS remains active as long as the instrument is ready to receive data
Example: :SYST:COMM:SER:CONT:RTS ON *RST value is RFR
:SYSTem:COMMunicate:SERial:PACE XON | NONE
The command sets the software handshake. *RST has no influnence on this parameter.
XON Software handshake using the ASCII codes 11h (XON) and 13h (XOFF).
Note: This mode is not recommended for binary data and for baud rates above
9600 bauds.
NONE No software handshake.
Example: :SYST:COMM:SER:PACE NONE *RST value is NONE
:SYSTem:ERRor?
The command queries the entry that has been in the error queue for the longest time. Positive
error numbers denote errors specific of the instrument, negative error numbers denote error
messages specified by SCPI (see annex B). If the error queue is empty, 0, "No error", is returned.
The command is identical to STATus:QUEue:NEXT?
Example: :SYST:ERR? Response: -221, "Settings conflict"
