Page 11: System Description
Instruction manual for devices of the MASI20 series 2 System description 2.1 AS-i system The AS-Interface is a simple and cost-saving wiring system based on a 2-wire cable for data and power transmission to sensors over a distance of up to 100 m. System expansion > 100 m is possible with the use of repeaters. - Page 12 Instruction manual for devices of the MASI20 series Owing to the signal shape for the data transmission, it is not necessary to provide terminating resistors. Thanks to the intelligent data protocol, AS-Interface systems are extremely non-sensitive to disturbance. Consequently, you can use a non-screened bus cable.
