Channels
I/O cards give the server channels. The card it ships with gives CH1 to CH4. 8-channel and 16-channel cards fit the other slots.
Hook something up
Run a control cable from a channel's jack to anything with a CTL jack:
- a grow bed's light, sprinkler, feeder, hose or clip fan
- an aquarium's auto-feeder
- a lamp or a neon sign
- any rack device: the channel switches its power
- the water tap's valve
That cable is the whole hookup. Nothing is wireless. To reach another room, patch the channel into a patch panel and trunk it to a panel in that room.
Programs
- OFF and ON. A switch.
- TIMER. Grow-clock hours. 0 to 18 keeps a bed in veg, 0 to 12 flowers it.
- INTERVAL. On for some seconds, off for some seconds.
- RULE. On while every line holds: this channel's reading, another channel's, or the lab's (grow hour, the clock, an outage, the bill, heat, an intrusion, open faults).
- BAND. A thermostat. Start below one line, stop above another.
band this.water 40 80waters only the plants that need it.
Programs act only while the server runs and the channel has a card and a cable behind it. Otherwise the thing holds its last state.
Terminal
auto lists every channel. auto <server> ch3 preset watered, timer 0 18, band this.water 40 80, when this.tank < 30.
