system to pass serial command signals between the transmitter and
receiver, for example for serial control of a projector, connect the host device
to the transmitter and the secondary device to the receiver via the leftmost
three poles on the left (Tx, Rx, and

) of the 5-pole captive screw connectors on both
units (see RS-232 connectors on page 12 to wire this connector).
NOTES:
•
If you connect only one fiber optic cable (

on page 8), or you configure
the receiver for daisy-chaining, you do 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
to the
receiver or using the
FOX Extenders Control Program
).
• The PowerCage FOX Extender can pass RS-232 commands and responses at
rates up to 115200 baud.
