This document describes the connection method of ARF62 in the DUN configuration, including the correct connection method and the incorrect connection method.
The document provides a wiring diagram and text description for configuring the ADEUNIS ARF62 in a Dual Unit Network (DUN) profile. It details the required connections between PC/DTE and Modem/DCE sides using DB9 Male and Female connectors.
Crucially, it defines strict constraints for operation: the Master unit must be the DB9 Female connector, while the Slave unit must be the DB9 Male connector. The text warns that failing to respect these roles can lead to I/O conflicts and damage the product.
