3.7 Electrical Characteristics
3.7.1 Electrical Specifications:
3.7.2 The DVD-301-01-x utilizes one (1) 15-pin connector for electrical
connections, which provides power, data bus control, infrared input,
and three (3) address strapping pins and a strapping common for
unit identification on the RS-485 data bus and for IR control.
3.7.3 Infrared input provides a ground reference connection (-). For
optimum infrared signal transmission, this ground reference should
connect to the IFR-9A or IFR-485 module being utilized.
3.7.3 The three (3) address strap pins are able to be connected to the
strap common. This provides eight (8) strapping configurations,
allowing up to eight (8) identical units to be individually controlled
on a system.
3.7.4 The fiber optic transceiver connector (J2) allows proper digital
audio output to the audio distribution system.
3.7.5 The video output connector (BNC1) allows proper video output to
the video distribution system.
