b) General Rules
The general rules for parameter usage are as follows:
• Numeric parameters may have up 15 significant digits
and their value can be in the range +/-1.0E+/-20.
• Including too many or too few parameters causes a
command error.
• Null parameters cause an error, e.g., the adjacent
commas in OUT 1V, ,;OPER.
• Expressions, for example 4+2*13, are not allowed as
parameters.
c) Extra Space or Tab Characters
In the command descriptions, parameters are shown separated
by spaces. One space after a command is required (unless no
parameters are required). All other spaces are optional. Spaces
are inserted for clarity in the manual and may be left in or
omitted as desired. You can insert extra spaces or tabs between
parameters as desired. Extra spaces within a parameter are
generally not allowed, except between a number and its
associated multiplier or unit.
d) Terminators
Table 8 summarizes the terminator characters for both the IEEE-
488 and the RS-232 remote interfaces.
Table 8 - Terminator Characters
Terminator Function ASCII Character Control Language
Command Command
Number Program Terminator Terminator
Carriage Return (CR) 13 Chr(13) <Cntl> M \n
Line Feed (LF) 10 Chr(10) <Cntl> J \r
Backspace (BS) 8 Chr(8) <Cntl> H \b
Form Feed (FF) 12 Chr(12) <Cntl> L \f
Examples:
RS-232 Mode, terminal: OUT 1 V <Enter>
RS-232 Mode, program:Comm1.Output = "OUT 1 V" + Chr(10)
IEEE-488 Mode:
OUT 1 V
IEEE-488 interface:
The CL3001 sends the ASCII character Carriage Return
with the EOI control line held high as the terminator for
response messages. The CL3001 recognizes the
following as terminators when encountered in incoming
data:
• ASCII CR character
