command signals to a secondary device, for serial control of a projector for
example, connect the secondary device to the receiver via the first three
leftmost poles (Tx, Rx, and

) of this 5-pole captive screw connector ( see
“ RS-232 connectors “ on page 9 to wire this connector).
NOTES : • If you connect only one fiber optic cable (see item
Ä
, above), or you
configure the receiver for daisy-chaining, you will not receive reports
from the controlled device. To receive responses from the controlled
device, you must install two fiber optic cables and leave link 2 enabled
(via an
SIS command [see page 18] or using the Signal Processing
Product Control Program [see page 24]).
• The PowerCage FOX can pass RS-232 commands and responses at
rates up to 115200 baud.

that the associated signal is input (transmitter) or received on the fiber optic
cable (receiver).
Video — The unit is sensing an HDMI input signal.
HDCP — The input signal is HDCP encrypted.
Audio
— The unit is sensing an audio input signal above –35 dBV. The LED turns off if
the audio signal level drops below the threshold for 10 seconds.
