    2. Introduction The V.35 ↔ RS-422 Interface Converter comes in both 115-VAC (IC483A-R2) and 230-VAC (IC483AE-R2) standalone units. A card version (IC483C-R2) is available for rack-mounting. 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.

    3. Installation 3.1 DIP Shunt Settings V.35 ↔ RS-422 Interface Converter has two jumper-selectable configurations determined by DIP shunt settings located inside the unit on the printed circuit board. One configuration is for connecting a V.35 DCE device to a 422 DTE device, and the other is for connecting a V.35 DTE to a 422 DCE device.
  • Page 8 To install the V.35 ↔ RS-422 Interface Converter, follow these steps and refer to Figures 3-1 and 3-2. 1. Set jumper XW6 to the V.35 side when configuring the V.35 side of the unit as DTE. Set XW6 to the 422 side when configuring the RS-422 side of the unit as DTE.

    4.2 Pin Connections Figures 4-1 and 4-2 show the pin connections for the V.35 ↔ RS-422 Interface Converter. The pins that are grayed out in these figures indicate signals tied to the front-panel LEDs only. The Converter is shipped with the RS-422 port configured as DCE and the V.35 port configured as DTE. 1 In this configuration, pins 12 and 30 are inputs.
