Polaris G
Ten relay channels. Drive anything that takes a contact.
What it does, plainly.
Polaris G is the workhorse. Ten general-purpose GPIO channels on D2–D11, expandable to twelve with D12/D13 enabled in firmware. Default behavior is active-LOW into an opto-isolated relay bank — the same way professional show systems have driven props for thirty years. Wire it to a pneumatic solenoid, a maglock, a fog machine, or a strobe; Polaris G doesn’t care what’s on the other end of the contact.
10 channels stock on D2–D11; toggle the firmware flag for 12 on D12/D13.
Opto-isolated relay bank rated 250 VAC / 10 A per channel.
Active-LOW default matches every show-control convention from the last three decades.
Per-channel pulse, latch, and toggle modes — selectable from Cuemaster or the API.
