Parameters
The 3159 uses parameters composed of decimal numbers. There are three
different formats for decimal data: NR1, NR2, and NR3. Each has two
values: one with a code and one without it. A value without a code is
regarded as a positive number. If a number exceeds the accuracy resolution
of the 3159, the value is rounded up or down.
NR1 format: Integer data
+12, -23, 34
NR2 format: Fixed point numbers
+1.23, -23.45, 3.456
In the 3159, a format is specified for each command. (See Section 9.5)
Delimiter
Depending on transmission direction, the delimiter is as follows.
From computer to 3159: CR or CR + LF
From 3159 to computer: CR + LF
