Return to Section 10 topics
3. SYST:COMM:SER:CONT:RTS <name> ‘ Select hardware handshaking.
This command enables (IBFull or RFR) or disables (OFF) hardware hand-
shaking.
4. SYST:COMM:SER:PACE <name> ‘ Set flow control.
This command sets software flow control; XON to enable or OFF (default) to
disable.
5. SYST:COMM:SER:TERM <name> ‘ Set terminator.
This command selects the output terminator, CR, LF (default), CRLF, or LFCR.
6. SYST:COMM:SER:BAUD <n> ‘ Set baud rate.
Sets RS-232 baud rate: 300, 600, 1200, 2400, 4800, 9600, 19.2k (default),
38.4K, 57.6K, or 115.2K.
The following two commands cannot be sent to the Model 622x over the RS-232
interface, but instead make use of the instrument to send and receive data
through the GPIB or 6221 Ethernet interface via the 622x RS-232 port to another
instrument such as a Model 2182 (purchased separately).
7. SYST:COMM:SER:SEND <data> ‘ Send serial data.
Sends data from one instrument to another through the serial port. Strings,
such as commands to another instrument must be delineated with quotes ("").
8. SYST:COMM:SER:ENT? <name> ‘ Read serial data.
Reads data from another instrument through the serial port.
9. SYST:LOC ‘ Take unit out of remote.
SYST:REM ‘ Put unit in remote.
SYST:RWL <b> ‘ Enable/disable local lockout.
These three commands work with the RS-232 interface only. REMote is the
same as the IEEE-488 REN command and puts the unit in remote. LOCal
works like the IEEE-488 GTL command and takes it out of remote and returns
it local. RWLock is similar to the IEEE-488 LLO command and enables or dis-
ables local lockout. See “General IEEE-488 bus commands,” on page 10-22
for more information.
10. SYST:COMM:ETH:ADDR <string> ‘ Set IP address.
This command sets the IP address of the Model 6221. The address parame-
ter is of the form “n.n.n.n”, where each n is a decimal representation of a sin-
gle byte with a value of 0 to 255. Note that the IP address parameter must be
enclosed in quotes. Example: SYST:COMM:ETH:ADDR “145.90.120.240”.
11. SYST:COMM:ETH:MASK <string> ‘ Set subnet mask.
This command sets the subnet mask of the Model 6221. The mask parameter
is of the form “n.n.n.n”, where each n is a decimal representation of a single
byte with a value of 0 to 255. Note that the mask parameter must be enclosed
in quotes. Example: SYST:COMM:ETH:MASK “255.255.255.0”.
