NOTES: • If you connect only one fiber optic cable ( item q , on the next page), 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 to the receiver or using the FOX Extenders

• The FOXBOX can pass RS-232 commands and responses at rates up to
115200 baud.
