RS-232RS-422 INTERFACE CONVERTER

3. Installation

To connect the Converter to your devices, follow these steps:

1.Attach the cable from the RS-422 device to the 37-pin female receptacle on the rear panel of the Converter.

2.Attach the cable from the RS-232 device to the 25-pin female receptacle on the rear panel of the Converter.

3.Plug the 4-pin power cord into the receptacle on the rear panel of the case. However, don’t plug the power module into an AC outlet at this time. You can power up only after you have configured the Converter’s DTE/DCE DIP shunts (Section 3.1).

3.1 Configuration

The Converter’s RS-232 and RS-422 ports must each be set for DCE or DTE operation. Configuration is accomplished through DIP shunts located inside the unit on the printed circuit board (see Figures 3-1 and 3-2). One configuration is for connecting RS-422 DCE to RS-232 DTE. The second configuration is for connecting RS-232 DCE to RS-422 DTE. Refer to Table 3-1 for the DTE/DCE settings appropriate to your application.

Table 3-1. DTE/DCE DIP Shunt Settings.
