in communication, the instrument can enable software handshake. The high-level
language software engineer should compile the computer communication software strictly
according to the following handshake protocol:
The instrument command parser accepts only ASCII format, and command response
also returns ASCII code.
The command string sent by the host must end with NL ('\n'), and the instrument
command parser does not start executing the command string until it receives the
terminator.
Instrument can set instructions to shake hands: the instrument receives a character,
immediately after the character back to the host, the host only receives the return
character can continue to send the next character.
Tip: If the host can't accept the data returned by the instrument, you can try to solve it by
using the following methods:
1
.
The software handshake is closed, please refer to the instrument < System Settings >
page to turn it on.
2
.
Serial port connection failure. Please check cable connection.
3
.
The communication format of the high-level language program is wrong. Please try to
check the serial port number.is the communication format correct And whether the baud
rate is the same as that of the instrument.
4
.
If the instrument is parsing the last command, the host will not be able to receive the
response of the instrument. Please try again later.
<The problem is still not resolved. Please consult the technical engineer of Jinke
instrument immediately>
8.3 SCPI language
SCPI-Standard Commands for Programmable Instruments(Standard commands for
programmable instruments)It is a general command set used by Jinke instrument for
testing instruments. SCPI is also known as TMSL-Test and Measurement System
Language( Measurement System Language). Developed by Agilent Technologies based
on IEEE488.2, it has been widely used by test equipment manufacturers.
The built-in command parser is responsible for various user command format parsing.
Since the command parser is based on the SCPI protocol, but not entirely consistent with
the SCPI, please read the "SCPI Command Reference" chapter carefully before you start
work.
