* For laying a long bus or in conditions of increased interference (for example, in a shield) - use a twisted pair cable, for example, Cat 5, better shielded. | * For laying a long bus or in conditions of increased interference (for example, in a shield) - use a twisted pair cable, for example, Cat 5, better shielded. | ||
A twisted-pair connection is a signal on one core of the pair, ground on the second, and similarly power supply: plus power on one core of the pair, minus on the second. Connect the power negative to signal ground. Connect the screen on one side to the minus power supply. | |||
