  • Page 11: Configuration And Installation

    V.24↔V.35 INTERFACE CONVERTER 3. Configuration and Installation The converter installs between an RS-232 device configured as DTE or DCE and a V.35 device configured as DCE or DTE. (If one device is configured as DTE, the other device must be configured as DCE, and vice versa.) You configure the cable to fit your equipment by moving a jumper on the circuit board inside the RS-232 connector.
  • Page 12 CHAPTER 3: Configuration and Installation The converter is factory-strapped for V.24 DTE/V.35 DCE as shown in Figure 2. Figure 2. V.24 DTE , V.35 DCE. To configure the cable for V.35 DTE/V.24 DCE, follow these steps: 1. Locate the RS-232 connector on the cable. 2.
  • Page 13 V.24↔V.35 INTERFACE CONVERTER 4. Remove the DTE/DCE socket by gently grasping both sides and slowly moving it from side to side. 5. Turn the socket around and replace it so that the DCE side (labeled on the socket) faces the V.24 connector of the cable and the DTE faces the V.35 device (see Figure 3).
