3.1 Low-Speed Data Port Connector

The STB connector type will be a standard DB-9F or RJ22 (4 way/4 position jack). The pins for
the DB-9F are as shown in Figure 1. The STB will use three (3) lines (L2-Rx, L3-Tx and L5-
Grnd) for bi-directional full-duplex communications. Figure 2 shows the orientation of the RJ22
(4 way/4 position jack).
Line positions, designated as "optional", may be provided (but are not required to be provided)
by the STB as a convenience to source a "TRUE" state to those PC serial interface lines that may
require a "TRUE" state for data transfer.
