    5.4. Cooperation with other devices (lateral bus) Once the traps opened (see chapter 4.3. Lateral bus on page 7), the S4AO can be connected to to others LUMEL devices which are also equipped by a lateral bus. All devices can be RS-485 and the Master is connected at an extremity, or one device is set as RS-485 Master and monitors others devices.
