Questions answered in SN-221C manuals
How do I set the pan‑tilt drive voltage?
Use the JP3, JP4, JP5 jumpers on the board: JP5 is common, connect JP4 to set 24 V AC, or connect JP3 to set 220 V AC.
How can I adjust the lens drive voltage?
Set the three‑pin jumper T1: connect it to the “6V” side for 6 V DC, or to the “12V” side for 12 V DC.
