    RS-232↔CURRENT LOOP INTERFACE CONVERTER 3. Configuration and Installation The RS-232↔Current Loop Interface Converter is easy to use. It contains no internal jumpers or DIP switches to set, so you’ll never have to open the case to configure the unit. The only configuration required for operation is proper setting of the external DCE/DTE switch.

    CHAPTER 3: Configuration and Installation loop side of the Converter to the current-loop device interface. For best results, these 4 wires should be in twisted pairs. To install the Converter in an active current-loop environment, you will need a DB25 cable with at least 4 conductors. These conductors should be wired to the appropriate DB25 pins as shown in Figure 3-2.
