motion_cm-19 connet RS485 to LM5-RIO2

[admin]

Create an event script attached to a 1-byte unsigned object (valid scene number is from 1 to 15), change CM-19 address (default is 1) and port (default is /dev/RS485-1) if needed.

Code:

addr = 1 -- CM-19 address (default 1)
scene = event.getvalue()

if scene > 0 and scene < 16 then
  value = string.format('!BR%dg%X;', addr, scene)
  port = require('serial').open('/dev/RS485-1', {
    baudrate = 9600,
    duplex = 'half'
  })
  port:write(value)
  port:close()
end
