V.35/EIA-232 Interface

The V.35/EIA-232 interface cards can conform to V.35 (factory) or EIA-232 D/E by means of two slide switches and a DIP switch. Slide the switches toward the front of the UTA220 to select V.35 and toward the rear of the UTA220 to select EIA-232 D/E (Figure 3-4).

To complete the selection of EIA-232 D/E, set the DIP switch as indicated in Table 3-1. The following sections describe how to change DIP switch settings.
