ADAM-4571L ModuleThe ADAM-4571L is a fast and cost effective data gateway between serial and Ethernet interfaces. The unit also brings the advantages of remote management and data accessibility to RS-232 devices. The transmission speed of the units is up to 921.6 kbps, meeting the demands for high-speed data exchanges. In addition, you can use the Windows utility to configure the ADAM-4571L without further programming. The unit not only protects your current hardware investment but also ensures future network expandability. Since the protocol conversion is transparent, all your existing devices can be seamlessly integrated with an Ethernet network. Therefore the ADAM-4571L can be used in security systems, factory automation, SCADA, transportation and more. The ADAM-4571L links your existing human-machine interface (HMI) PC and your RS-232 devices with Ethernet cables. The ADAM-4571L comes with a Windows configuration and port-mapping utility. The configuration tool can auto-detect all Ethernet Data Gateway devices on the local network, and let you adjust all settings. The port mapping utility helps you to set-up COM ports for Windows NT/2000/XP platform. This helps you configure all ports to meet your requirements.
