The ToolLink™ family of compact gateways connect RS232-based equipment directly to a DeviceNet™ industrial network. The ToolLink™ gateways offer streamlined functionality to simplify out-of-box configuration and run-time operation in DeviceNet™ applications. The CDN466 and CDN466-5 are compact DeviceNet to RS232 serial gateways, where the gateway is acting as a DeviceNet slave. The units are housed in a 2½ X 3¼ plastic housing with mounting tabs. A 5 pin micro connector provides the DeviceNet interface and a 9 pin D connector provides the RS232 interface. The DeviceNet channel is fully isolated from the supplied power.
The CDN466 and CDN466-5 may be used to interface peripheral devices such as a bar code reader to a DeviceNet system. The RS232 serial stream is internally buffered, allowing a Master node to send and receive data using standard DeviceNet messaging. The power is conditioned by a loss-of-ground protection circuit and applied to a non-isolated DC-DC converter to provide 5 volts at 500 mA. A Newport NML0505S isolated DC-DC converter is used to provide power to the DeviceNet channel and the unit; no external power supply is required.
