2. Introduction
The V.35↔RS-422 Interface Converter comes in both 115-VAC (IC483A) and 230-VAC (IC483AE) standalone units. A card version (IC483C) is available for rackmounting. The rack (RM060) is switch-selectable for either 115-VAC or 230-VAC operation.
The V.35↔RS-422 Interface Converter provides bidirectional conversion of all the commonly used V.35 and RS-422 signals. The unit operates with one port configured as Data Terminal Equipment (DTE) and the other port configured as Data Communications Equipment (DCE).
The unit has two jumper-selectable configurations. One connects RS-422 modem equipment to V.35 terminal equipment (DCE to DTE). The other connects V.35 modem equipment to RS-422 terminal equipment (DTE to DCE). Both configurations allow bidirectional data transfer. Typical applications are shown in Figure 2-1.
NOTE
The Converter is configured opposite of the equipment you are connecting.
