  CANdo Interface    (P/N NET50003)
CANdo is a compact USB to CAN interface, that allows a PC to be connected directly to an embedded CAN bus. In conjunction with the FREE CANdo Application software, CANdo provides a simple, yet powerful means of testing & analysing a CAN network. The FREE CANdo SDK allows CANdo to be easily integrated into any Windows based program.

Notes :
  1. The CANdo Interface contains no internal CAN bus termination
  2. The CAN bus must be terminated at either end with a 120 Ohm resistor, although a single 120ohm resistor will suffice for short cable lengths (< 2m)
  3. For long CAN networks (>10m) & in noisy environments the use of screened, twisted pair wire is recommended
Customised versions of the CANdo Interface are available upon request. Please use the 'Support' page to request further information about this service & the different options available. An MOQ of 20 off generally applies to all custom orders.
