You can't use a profile because this is a custom protocol not Modbus.

For testing purposes use an event script. Change baudrate, parity and command bytes as needed.

Code:

require('serial')

port = serial.open('/dev/RS485-1', {
  baudrate = 9600,
  parity = 'even',
  duplex = 'half'
})

command = string.char(0x55, 0x01, 0x01, 0x03, 0x02, 0xF9, 0x01)
port:write(command)

If the test script works then it can be modified to send different commands depending on the input value. 4-bit value should work (e.g. up/down/stop).
