Hardware Installation

Mechanical assembly

BCS is manufactured using an anodized aluminium enclosure with enhanced EMI shielding and IP protection. A high reliability connector is also provided in this version. The total weight of standard version is 190g.

Dimensions

Veronte BCS dimensions (mm)

M3 screws are recommended for mounting. In saline environments such as coastal and oceanic, the screw material must be stainless steel.

Antenna Integration

The system uses different kinds of antennas to operate that must be installed on the airframe. Here you can find some advice for obtaining the best performance and for avoiding antenna interferences.

• Antenna Installation

  • Maximize separation between antennas as much as possible.

  • Keep them far away from alternators or other interference generators.

  • Always isolate antenna ground panel.

  • Make sure the antenna is securely mounted.

  • Always use high-quality RF wires minimising the wire length.

  • Always follow the antenna manufacturer manual.

  • SSMA connections shall be tightened applying 1 Nm of torque

  • For all-weather aircraft, insert SSMA lightning protectors.

Electrical

Power

BCS can use unregulated DC (6.5V to 36V).

LiPo batteries between 2S and 8S can be used without regulation needs. Remaining battery level can be controlled by the internal voltage sensor and by configuring the voltage warnings by software.

For higher voltage installations, voltage regulators must be used. For dimensioning voltage regulators take into account that a blocked servo can activate regulator thermal protection.

Warning

Power out of range can cause irreversible damage to the system. Please read carefully the manual before powering the system.

Electrical diagram of CAN bus

BCS includes an internal resistor of 120 Ω. A second resistor is required at the end of the line (again 120 Ω) to allow the connection of multiple CAN Bus devices to the same line. This resistor may be placed on cable or PCB.
