1.3 Details of the RS-232C Interface
Messages are classified as shown below:
Of these, program messages are those received by the unit from the personal
computer, while response messages are those sent from the unit to the
personal computer.
(1) Program messages
Program messages can be divided into either command messages or query
messages.
Command messages are orders for control of the unit, such as for making
settings or for reset or the like.
Query messages are orders for responses relating to results of operation,
results of measurement, or the state of device settings.
(2) Response messages
After a query message has been received, a response message is produced the
moment that its syntax has been checked. It is also possible to change the
message unit separator of response messages from the semicolon ";" to the
comma "," , using the command "TRANsmit:SEParator". Initially this
separator is set to the semicolon ";".
A space is represented by " "(space) in this manual.
Headers on "V +101.2E+0;A +1.200E‑3"
Headers off "+101.2E+0;+1.200E‑3"
(3) Execution confirmation message
Execution confirmation message is the numeric data created by analyzing and
executing one line of data (data up to the terminator) from the personal
computer. This numeric data is returned to the personal computer. The
personal computer and this unit are synchronized by means of this data.
