the jack the controller is connected to will both start flashing, verifying that the remote device's
responses are reaching the controller.
Therefore, after a bi-directional connection has been successfully established, four LEDs will
continuously flash while the data connection is active: a green and a yellow one at the jack
corresponding to the DE9 connector that the controller is connected to, and a green and a yellow
one at the jack corresponding to the DE9 connector that the remote device is connected to.
In addition to the DE9 connector pins required by the Sony Protocol of Remote 9-Pin Connector
and the RS422 Protocol, the Bittree RS422 Active Data Patchbay also switches and routes pin 5
of the rear panel DE9 connectors, as shown in Figure 3. This pin is designated as "spare" by the
Sony Remote Delegation protocol, but is used in some installations for priority signal routing.

Diagnosing Connectivity
Table 2 below summarizes some possible abnormal conditions, potential causes, and suggested
actions. A controller is assumed connected to Port 1 and a remote device is assumed connected
to Port 2. It is assumed that both the controller and the remote device are powered-up,
configured and connected to DE9 connectors on the rear panel of the patchbay. The two jacks
that correspond to those DE9 connectors are assumed patched together, either via an internal
normaling connection (i.e., they are vertically aligned) or through an external patchcord. Please
ensure that there are no "hanging" patchcords (i.e., patchcords with only one of the two ends
connected) between the jacks in question.
NOTE: If you experience an LED flashing/off combination that is not listed in Table 2 below,
then the patchbay may possibly be exhibiting an internal fault. Please call Bittree Customer
Service for further assistance.
