These interfaces provide all of the control commands and parameter setting commands of
the GPIB interface with the exception of the 488.2 Common Command the Status Reporting
commands and SRQ capability.
For information on supported programming commands, refer to section 7, “Remote Control
Programming”. The identification command *IDN is also available through USB, RS-232 and
LAN interfaces.
5.12.6
Sending Commands over RS232 / USB or LAN
When sending commands over the RS-232 interface, the instrument will send a response
string of 0x06 (HEX), 6 decimal acknowledge (ACK) ASCII control code if the transfer was
recognized and completed by the instrument. If there is an error with the command string
that is sent, the instrument will respond with an 0x15, 21 decimal Not Acknowledge (NAK)
ASCII code. The ACK or NAK response supports software handshaking in order to monitor
and control data flow.
5.12.7
Receiving Commands over RS232 / USB or LAN
When requesting data from the instrument, it will automatically send the data back to the
controller input buffer. The controller input buffer must accumulate the data being sent
from the instrument including the ACK and NAK response characters, until the controller has
read it. When a string or command has been sent, it
must
be terminated by a Linefeed
character (0x0A), for example ”TEST”+LF.
