*SEC <Addr> Secondary Address
<Addr>
Parameter description Def. value Default unit FW vers.
0 to 29 Secondary address 0 – V1.20
Command description
This command has no query form. It switches over to the specified secondary address. It is required if the serial
interface is used for remote control (software switchover, RS-232 remote interface, see previous command and
section Setting the Device Address in chapter 5).
Subsystem Communicate
The COMMunicate subsystem contains the commands for configuration of the remote serial interfaces.
It corresponds to the Communicate tab in the Setup menu opened via the SETUP key on the front
panel. The parameters set in this subsystem are explained in more detail in chapter 8, section Hard-
ware Interfaces.
SYSTem:COMMunicate:GPIB[:SELF]:ADDRess <Addr> Primary Address
<Addr>
Parameter description Def. value Default unit FW vers.
0 to 30 Primary address to the GPIB (IEEE) bus 20 – V1.20
Command description
This command sets the primary address of the GPIB driver which is used to address the device (CMU).
It is equivalent to SYSTem:REMote:ADDRess:PRIMary (see above).

Command description
This command is always a query. It returns the current application (connection) of the serial (RS-232) interface.
The numeric suffix distinguishes the two interfaces COM 1 and COM 2.
SYSTem:COMMunicate:SERial<1|2>[:RECeive]:BAUD <Baudrate> Baud Rate
<Baudrate>
Parameter description Def. value Default unit FW vers.
110 | 300 | 600 | 1200 | 2400 |
4800 | 9600 | 19200 | 38400 |
57600 | 115200
baud rate 9600 baud V1.20
Command description
This command sets the baud rate of the serial interface no. 1 or 2 (connectors COM 1 or COM 2). If a COM port
is selected as an GPIB connector, the default transmission rate is 19200 baud.
