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.
