As a side note; we should be able to get screen captures via USB and LAN (ethernet).

But, I can only get USB working (as you have seen) for getting these screen captures. The LAN works, but I cannot get the RIGOL to respond to control commands (LXI), but it should.

The legacy web interface works, for example see:

and of course I can ping it (goes without saying since we can access it using HTTP):

Code:
macos$ ping 192.168.2.50
PING 192.168.2.50 (192.168.2.50): 56 data bytes
64 bytes from 192.168.2.50: icmp_seq=0 ttl=255 time=3.210 ms

64 bytes from 192.168.2.50: icmp_seq=5 ttl=255 time=1.873 ms

Scanning the RIGOL DS1054Z had revealed:

Code:
macos$ nmap 192.168.2.50
Starting Nmap 7.80 ( https://nmap.org ) at 2020-01-18 11:16 +07
Nmap scan report for 192.168.2.50
Host is up (0.0041s latency).

111/tcp  open  rpcbind
617/tcp  open  sco-dtmgr
5555/tcp open  freeciv

Nmap done: 1 IP address (1 host up) scanned in 1.28 seconds

But so far, cannot get this RIGOL to respond to either nc or telnet commands.

Code:
macos$ telnet 192.168.2.50 5555
Trying 192.168.2.50...

This is really perplexing me. We can see from this screen grab that the LAN I/O is off, but I cannot find a way (yet) to turn it on.....

If I could only figure out how to turn the LAN I/O on ....

UPDATE:

The USB and the LAN cable cannot be used at the same time.... so when I removed the USB cable, the LAN shows "ON"... (see next post)

Figured this out.....

When the USB is plugged in, it overrides the LAN. If I unplugged the USB, and then rebooted, it worked.


Code:
maco$ telnet 192.168.2.50 5555
Trying 192.168.2.50...

So, later when I'm back from hiking the the mangrove swamps, will try to get some screen captures over the LAN.

Progress!

Great scope! Awesome for the money, really a bargain at this price.

rigol_grab.py also works over the LAN.

Code:
(rigol-grab) bash-3.2$ python  rigol_grab_bmp.py -f via_lan.bmp -p 192.168.2.50 --auto

More pretty noise, showing "LAN ON"

Bench Test Kit also works to grab RIGOL screens (over the LAN only):

Code:

Code:

More pretty noise, this time using channel 2:

This pretty much wraps up Python Screen Capture of RIGOL 1054Z on macOS Catalina Using NI-VISA.

Hope at least one RIGOL user finds this helpful.

Final capture at the standard 800px width (versus the 1024px width I have created by enlarging 800px to 1024px width). JPG capture.

Note, the best way to get JPG capture to work on this RIGOL is to specify the JPG file type in the LXI command; but name the file with the .jpeg extension. This works best, consistently, for JPGs for some reason yet explained. But, if you don't want this confusion, go with BMP images, which are consistently better, with the BPM24 option, and file extension .bmp.
