The XpressNet� is a network similar to a computer network. XpressNet� connects several input devices with the command station. Input devices can be manual controls as well as interfaces for connection to a PC or router.
From a technical point of view the XpressNet� is a RS485 gateway, thus beeing an industrial standard. Data are sent with a speed of 62,5 kBaud. The command station assigns time slots to max. 31 input devices, during these time slots a device can sent information to the command station. Thanx to the protocol used the devices may be connected and disconnected on the flight which is for instance profitable when operating a large layout: you can disconnect your manual control and connect it on the other end of the layout without "forgetting" any information. The connection comes by 5-pin DIN plugs or "Western" plugs and for instance the adapter LA152.
Das network is set up with 4 core cable. Two cores supplying the power for the connected devices and two cores processing the data transfer.
There is no special topography recommended for the XpressNet�, but loops may not be built. Lengths up to 1000 meters have already been realised without problems.
