The RS-449 Interface Adapter performs the necessary adjustments between an RS-449 Interface and an RS-232 interface to allow direct connection of both. Electrical, functional and mechanical considerations have been implemented in accordance with the EIA recommended standard for interconnection between interface circuits using RS-449 and RS 232.

The RS-449 Interface Adapter is available in two basic models: Model 387 configures RS-232 as Data Terminal Equipment (DTE) and RS-449 as Data Communications Equipment (DCE). Model 487 configures the RS-232 as DCE and RS-449 as DTE. Both adapters are equipped with a single two position CH with SR and CI with SI. When installing either model in a system, it is recommended that the maximum cable distance from the RS-449 receivers and drivers be kept to no more than ten (10) feet.
