The DPC CodeKey makes it easier to set parameters for the DPC device family. Once a reference device has been successfully programmed, the operating parameters are available in a device-memory readout. The parameters filed in the CodeKey can be copied into other devices any number of times. This reduces the programming work to a minimum. In addition, the CodeKey can be used as an interface converter between the USB and RS485.

Mode of Operation

A DIP switch can be used to select the device function required. The DPCfront and DPC III have at the side or under the display cover a 5-pin interface into which the CodeKey is inserted. The transmission is started at the press of a button. Once done, a status LED flashes. Voltage is supplied to the CodeKey through the interface.
