In addition to the commands and special characters that emulate the IEEE-488 functions shown above,
there are several more commands that are related to operation and control of the actual RS-232 or
Ethernet port and are therefore completely unrelated to IEEE-488/USBTMC operations. These include
these commands.
SP_SET SRQSTR?
SP_SET? SPLSTR?
Commands for IEEE-488 Only
The IEEE-488 checkbox indicates commands that are used for the IEEE-488 interface. This is all of the
commands, except for those used for RS-232/Ethernet operations, see Commands for RS-232/
Ethernet Only. All commands are transferred over the IEEE-488 as data, except for the commands
LOCAL, REMOTE, and LOCKOUT. These are implemented per IEEE-488.1 Standard as messages,
see Table 12.
Table 11. Commands for RS-232/Ethernet Only
IEEE-488 Message RS-232/Ethernet Equivalent
GTL LOCAL command
GTR REMOTE command
LLO LOCKOUT command
SRQ SRQSTR command
SDC, DCL ^C (<Cntl> C) character [clear the device]
GET ^T (<Cntl> T) character [execute a group trigger]
SPE, SPD ^P (<Cntl> P) character [print the serial poll string]
