The power supply can be connected to the host interface through the level conversion
circuit through the DB9 plug on the back panel. The following contents can help you
understand how to control the output of the power supply through the host computer.
1. Communication Settings
Before communicating, you should first match the power supply with the following
parameters of the control host:
(1) baud rate: 9600
(2) check: none (3) data bits: 8, stop bits: 1 (fixed value).
The DB9 interface of the power rear panel can be connected to the host's interface.

Chapter 6 SCPI communication protocol.
6.1 SCPI command overview
MPS-3600H series programmable DC power supply supports SCPI communication
protocol.Scpi is a standard command for programmable instruments. It defines a set of
command rules for communication. Commands for iv3600 series power are divided
into two main categories: basic command (ieee-488.2 common command set) and
MPS-3600H series specified command set.
The SCPI commands are arranged in a hierarchy of command trees. Each command
contains many strings (mnemonic symbols), and the layers are separated by colon (:).
The command at the top of the command tree is called "root command" or "root". To
access the next command, a path must be specified. The structure of the command
tree is as follows:
In the graph, AA represents the root path; BB, CC, DD represent the direct subpath.Ee
under the root path, FF, GG represents the subpath. Hh under the subpath BB, and JJ is the
subpath under the subpath DD.
Command description:
1) [:]aa:cc indicates that the root path is AA, and cc. is accessed under AA.
2) [[]aa:bb:ff] indicates that the root path is AA, and the ff. under the subpath BB under
the AA root path is accessed.
3) [[]aa:dd:hh] indicates that the root path is AA, and the hh. under the subpath DD

10
under the AA root path is accessed.
This command can also send multiple commands at the same time, separating the
commands with semicolons (()).
For example: []aa:bb:ee; FF; GG represents EE, FF, gg. under BB.
[:]aa:bb:ff:: aa:dd:hh represents hh. under FF and DD under BB access.
There are two types of mnemonic characters in SCPI language, that is, keywords, long
format and short format. Short format is actually abbreviation for long format.
The short format mnemonic is composed of the first 4 characters of the long format
mnemonic. If the length of the long format mnemonic character is less than or equal to 4,
the length mnemonic is the same.
* if the length of the long mnemonic is greater than 4 and the fourth character is vowel, the
short mnemonic will discard fourth characters and turn the vowel into 3 characters.
For example, the short mnemonic of ERR or is ERR, not ERRO..
Some commands need parameters, such as set value command. At this point, a space
between the command and its first parameter is required (ASCII code is 32).
For example, set the voltage value command [:]volt 12
There is a space between the parameters 12 and the volt command (ASCII code is 32).
The command set of SCPI is not sensitive to case, that is, the command is not case
sensitive, and each command has a terminator for the EOI: instruction to end <LF> (which
means ASCII code character 'n' ', that is, ASCII code line break, decimal 10, sixteen binary
0A).
Note: all the following instructions need to be added to the end of the instruction. The
square brackets [<lf>.] below indicate that the string can be written in the command or not.
6.2 MPS-3600H Power command set
6.2.1 basic command (ieee-488.2 common command set)
This command includes general functions defined in the ieee488.2 standard, which are
usually applicable to measuring instruments that support the ieee488.2 standard. This
command is started with asterisk (*) without hierarchical structure.
Command *idn?
This command can read the relevant information of the power supply, such as
manufacturer, product type, product serial number, firmware version number.
6.2.2 System command
The commands in this section are all commands under []SYSTem root path. The commands
given are all in a short mnemonic format.
Order []SYSTem:ERRor:?
This command is used to read the error code and error message of the power supply.
Return command: error code, error message
Example: send the command to [:]
SYST:ERR?
<LF>

11
The power returned commands are "0,'No Error'", or "50,'Error Para Count'", or
"70,'Invalid Command'" and so on.
Order [:]SYSTem:REM
The command is used to set up the power supply for remote control mode, that is, PC
control mode.
Return command: None
Example: send the command to [:]
SYST:REM
<LF>
After the transmission is successful, the front panel of the power supply is set to the remote
control mode. At this time, the key on the front panel is invalid. Only by pressing the Shift+
number 7 key, or sending the command []SYST:LOC: can the power supply be switched to
the front panel of the power supply.
Order [:]SYSTem:LOC
The command is used to set the power supply to the panel control mode.
Return command: None
Example: if the power is in remote control mode (PC) at this time, send the command
[:]
SYST:LOC
<LF>
After the transmission is successful, the front panel of the power supply has been set to the
front panel control mode.
6.2.3 Measurement command
The commands in this section are all commands under [MEASure root path. The commands
given are all in a short mnemonic format.
Order []MEASure:VOLTage:?
The command is used to read the output voltage value of the power supply.
Return command: numeric value
Return parameter unit: v
Example: the order sent is: [:]
MEAS:VOLT?
<LF>
At this time, the power return command is: 12.560, which means the current value of
the power supply is 12.560v.
