Hello,

I own a USG20-VPN firewall, and I want to connect its serial port to my Moxa device (out-of-band network).

The issue is that Moxa rj45 pinout is not the same as let's say Cisco's, or other vendors, which means that I always have to build my own serial cables, and that I cannot use the one that shipped with my Zyxel device (also, it is rj45 to DB9, instead of the rj45 to rj45 that I will need).

I have looked for some documentation on Zyxel's console cable pinout but I did not find anything I could use.

Would you be so kind as to provide me with some docs, schematics or anything?

Thank you so much for your help.

Kind regards,

M

    Hello @millisent41

    Welcome to the Zyxel community. Please prepare two console cables: one is DB9 to RJ45, which connects to the USG20-VPN, and the other is RS232 to USB, which connects to the PC's USB port, for console usage, as shown below :

    Please refer to the console below information :

    It's the console serial port setting in Tera Term.

    Speed : 115200 bps

    Data Bits : 8
