Eight Rs-422 inputs stackable hub with RS-232 port
The AP821 hub is designed to connect multiple Auper control systems to the same serial port on a computer running Auper software.
The AP821 has eight isolated RS-422 input ports, an RS-422 output port to connect it to another hub to expand the network, and an RS-232 port to connect it to the serial port on your computer.
The distance between two RS-422 devices can reach 1000 meters. The AP821 has been used in stadiums to connect multiple metering systems with flow meters distant from each other. Hundreds of flow meters are connected to the same software for flawless operation and a fully integrated beverage control system.
The AP821 hub is also used to connect several alcohol control systems to the same serial printer or to connect several alcohol control systems to the same point of sale terminal.
