Internal power supply and I/O addressing |
There is one USB host port facing down to connect to external devices, such as ADs, telephone modems, printers, memory expansions (USB “sticks” or hard disc drives), and expansion modules. The USB device port on the front is intended for program download from a PC by means of Device Administrator. It is connected to a PC or a downstream port of a hub.
The Ethernet communication is performed over a 10/100BaseTX, 10 or 100 Mbit/s, twisted pair network. AS-P has a built-in Ethernet switch with two ports connected to two RJ45 connectors. One port should be connected to the site network. The other port can be used to connect a single WorkStation or WebStation, a Modbus TCP unit, or a BACnet/IP device, but not another SmartStruxure server. By default, both ports are enabled for use. The Ethernet 2 port can be disabled if needed.
