Plugging In Front USB
After first powering up the used DSP-1283, no reset or other changes done by me, I checked for it on the network by looking for DHCP requests with the LAN port plugged in. Nothing was found.
The front USB port (for programing) does show a "COM3" and windows downloaded drivers for other devices too.
But when trying COM3 via putty via 9600 and 115200 baud an error comes up.
Pressing the setup button and connecting, booting with it held down and connecting, and other similar options produced no results.
I did note when the USB is plugged into a Linux box the system shows it as a "RNDIS/Ethernet Gadget". Finding the drivers here you can then access it. Or use Ubuntu 20.04 without any other drivers like I did.
After doing a tcpdump and finding the box doing DHCP requests on the USB interface, I setup a local dhcp server in docker and was able to do a port scan of it. That gave me 22, TCP/41794, and TCP/41795. I'm not sure what 41794 does yet. But 41795 is a telnet console server. You can login without creds or issues on mine.

DSP-1283>ETHERNET ?
ETHERNET [<device_num> ON | OFF [/now]]
device_num - 0..n
ON - enables LAN
OFF - disables LAN
/now - take effect without a reboot
No parameter - displays current setting
DSP-1283>DHCP ?
DHCP [<device_num> <ON | OFF> [/now]]
device_num - 0..n
ON - enables DHCP for device_num
OFF - disables DHCP for device_num
REL_RENEW - performs a DHCP release and renew for device_num
/now - take effect without a reboot
No parameter - displays current setting
With those two commands I easily turned on DHCP on the LAN interface (aka 0 or eth0)
DSP-1283>ethernet Ethernet 0 (eth0): On Ethernet 1 (eth1): Off
Then I connected in normally from my network using the DHCP address it pulled (the MAC is on a labal on the back of the unit) on TCP/41795 using telnet.
Turning Off SSL Verification
DSP-1283>ssl
SSL: Off, CA
DSP-1283>ssl ?
SSL [OFF| NOVERIFY | CA]
where 'OFF' turns off SSL,
where 'NOVERIFY' turns on SSL, but accepts any certificate from the control system without verifying it,
where 'CA' sets SSL to use 'CA' issued certificates (certificate authority ),
No parameter - displays the current setting
DSP-1283>ssl noverify
Reboot to take effect...
DSP-1283>reboot
Rebooting system. Please wait...
Enabling SSH
While I'm unsure if this would help, hurt, or what it'd do...
DSP-1283>sshpor ?
SSHPORT [OFF | ON | port number]
[OFF | ON ] - Disables/Enables SSH. Default is ON
portnumber - desired port number (in decimal).
no parameter - displays current value
DSP-1283>sshpor on
New SSH state settings. Reboot to take effect.
DSP-1283>reboot
Rebooting system. Please wait...

It does look *nix-ish.
