4-Pin DC Power Cord The 4-Pin DC Power Cord provides basic DC power input with the addition of two programmable signal lines. One of the signals lines is an input line, while the other can be configured as either an input or output line.
Wiring configuration WARNING! Only one of the power connectors should be used. Never apply power to both the MAIN and AUX connectors at the same time. The following figures illustrate typical wiring configurations for both input and output applications. The supply voltage is limited by the maximum allowed 28 V of the inputs. 4-Pin DC Power Cord User Guide...
The mode of operation of the input/output line is configured via CLI commands. These commands can be built into Python or basic scripts to automate functionality, or, entered manually via the CLI or SMS. For more information, please see the Digi TransPort WR User Guide, part number 90001019, on www.digi.com/resources/documentation/DigiDocs/PDFs/90001019.pdf...
