Access Denied - Serial on Netscreen RA500

Good day everyone,
Thank you for taking the time to read my post. I hope you’re able to assist with my dilemma.
I purchased a used Juniper Netscreen RA500 because I want to start learning JunOS (ScreenOS) for my future certifications. I use putty with the following settings:
Com1 which matches the prolific driver in device manager
baud = 9600
data bits= 8
Stop bit = 1
I’m using a straight-through cable connected to a Trendnet TU-S9 USB adapter. I confirmed it works on my Cisco products without issue. I thought hmm, maybe it’s the cable, so I purchased a FTDI serial cable to usb, and have the same results. Nothing appears in putty regardless of how many times I press “any” key. I used another machine that had SecureCRT installed, and I get a message that the serial port is “Access Denied”.
I’m not sure what the IP address is or if it’s even configured. I tried using nmap to scan the various private IPs but that is proving to be insane and time consuming. I reached out to the seller and should hope to have an IP or a refund shortly.
My question, which I apologize for being drawn out, are there any other methods for resetting this device to factory defaults? Any suggestions for what device I should get? Should I be focusing on JunOS or ScreenOS in regards to certs?
Thank you again and I hope you all have an amazing day.
