Operation of the industrial vehicle is managed by devices onboard the vehicle. One such management device includes a portable memory device issued to a person authorized to operate the vehicle. The vehicle control system, by reading data from the portable memory device, determines whether the person is permitted to operate that particular industrial vehicle and if so enables that operation. Another management device transmits a data signal through a power line on the industrial vehicle and uses a magnetically permeable wire bead in a unique manner to negate a short circuit effect that a component has on the data signal transmission. A further management device includes a module to interface a data acquisition module, designed to connect to a communication network of one type of industrial vehicle, for use with other vehicles. |
