AP7612 4-pin socket on the back

[ttl256]

Hello

What’s the purpose of a 4-pin socket on the back of AP7612? Pictures is attached.

It’s not covered in AP-7612 Wireless WiNG Access Point Quick Reference Guide and I couldn’t find additional information.

Ok then. Hope I’ll never need it) Thank you.

It's a TTL console. You normally never need it.
