adapter provides two 15-pin D-type ports: one for the SPR side; and the other for the
SDA side. The RSS LED adapter can be connected in one of the following manners:
! The RSS LED adapter 15-pin D-type port connects directly to the SPR’s 15-pin
D-type port; while the other RSS LED adapter’s 15-pin D-type port connects to
the SDA via the CAT 5 cable.
