Please help me with the following questions
I have an oscilloscope Rigol DP832 converted to an oscilloscope Rigol DP832A using the method mentioned in this topic
After the modification, I got the available options LAN, RS232, color display
Communication with the device on the network through the LAN interface is successful using software ULTRA SIGMA from the manufacturer

Communication of the device with the computer through PC232 is not established (Reaction is absent)
The scheme of connection is used: Computer with RS232 port-Cable RS232 (9 pins) - Oscilloscope Rigol DP832(A)

The RS232 cable has the following scheme of contact pins 1-1, 2-2, 3-3, ..., 9-9

Communication of computer - other measuring device (not Rigol) using this RS232 cable is normal

Questions:
1) What type of RS232 cable should I have (1- ?, 2- ?, 3 -?, ... 9-?)
2) What RS232 cable lines are really needed to control the Rigol DP832A) and receive/transmit data from/to it ?
3) Do I need to make any settings directly on the device?
4) Does the device have any specific parameters of communication with the computer on RS232 ?

User manual page2-56 explains pinout and settings including flow cotroll.

shico:
Sorry for typo: Oscilloscope - Power Supply. Post corrected. I am now very focused on oscilloscope programming and therefore all thoughts about oscilloscope

RoGeorge:
Without opening the manual, I will first try pin 2 to 3 and 3 to 2, aka Tx to Rx and Rx to Tx (and GND, of course).  So only 3 wires.

Usually the settings would be 9600, 8, N, 1, the most common default RS232 setting (but I don't have the manual right now, so better look up the DP832 user guide/manual).

You need:
-Computer with RS232 port
-USB stick formatted in FAT32 with the file keyfile.bin from Tossu (many thanks for the hack !)
-Cross cabel RS232 female-female (2->3; 3->2; 5->5)
-Free software Termite from Compuphase (https://www.compuphase.com/software_termite.htm)

Connect everything together. Start the computer first and launch Termite.
Termite Serial port settings:
-Port COM1 (depend on your computer)
-Baud rate 9600
-Data bits 8
-Stop bits 1
-Parity none
-Flow control none
-Forward none
-Transmitted text Append CR-LF

Turn on the DL3021
To check the connection, you can try to type *IDN? in the Termite command line.
He will return the model of your device.
Type in Termite :PROJ:SET MODEL,DL3021A
That all  :D

Hello friends

In 2021 I tried this on my new DL3021, with no success.  SW version is 00.01.05.00.01. RS232 works well. Command "*IDN?" returns product name, serial number and SW version. Command ":PROJ:SET MODEL,DL3021A" does nothing.
Any idea is welcome.
Thanks

Ed

I think you need a space after the comma: ":PROJ:SET MODEL, DL3021A"
