1. Introduction

Congratulations on your purchase of the new Bittree RS422 64-Port Active Data Patchbay. You
have purchased the latest innovation in data patchbays, which will help you accomplish your
RS422 patching with unprecedented speed and reliability. Please read this User Guide end-to­end to familiarize yourself with all of your patchbay’s features, and to ensure you will use it
safely and effectively.

1.1 Overview of the Patchbay

The new Bittree RS422 Active Data Patchbay delivers the most significant improvement in
RS422 patching since its inception, making it easier to route, manage, verify and diagnose
RS422 data connections.

The key innovation lies in the patchbay’s auto-sensing transceivers that receive, interpret and re­transmit perfectly regenerated RS422 signals, eliminating inductive and capacitive signal
distortion frequently imposed by traditional passive switches. The patchbay also provides a
powerful diagnostic tool that easily verifies the connection status between controllers and remote
devices (e.g., VTRs). The color-coded Indicator LEDs on the front panel display the
transmitting and receiving status of each device connected to the patchbay, providing you with a
reliable way to manage, verify and diagnose RS422 signals, as well as determine which devices
are set to “Master” and which to “Remote.”

The RS422 Active Data Patchbay enhances the mechanical and electrical reliability of your
RS422 connections. Mechanically, your system will be more reliable because it uses standard,
robust bantam (TT) audio jacks and corresponding bantam audio patchcords, as opposed to the
more fragile “card edge” patchcords used by competing 2 x 32 patchbays that can cost twice as
much. Electrically, your system will be more reliable because the patchbay transmits
regenerated, pristine RS422 signals.

In addition to the signal-enhancement, diagnostic capabilities and increased reliability described
above, the form-factor of the new RS422 64-Port Data Patchbay is more efficient than that of
competing models, thanks to its 2 x 32 port configuration that perfectly matches standard routers.

To ensure uninterruptible operation and unmatched reliability, Model 422A32-D features dual,
redundant power supplies and automatic internal power switching in case of anomalous events.
Dual power indicator lights on the front panel provide complete status information on both
power supplies and the patchbay’s power bus. Model 422A32 features a single power supply.

The RS422 Active Data Patchbay is ideal for multiple edit bays and machine rooms in post­production, broadcast and duplication houses. And because the patchbay also serves as a
repeater, it excels in today’s larger networked installations, helping to provide RS422 cable runs
of up to 8,000 feet, depending on the termination gear.

Front and rear views of the Bittree RS422 Active Data Patchbay, with annotations, are shown in
Figure 1 below.

Figure 1 – Front and rear views of the RS422 Active Data Patchbay

Two rows of 32 bantam audio jacks and two rows of 128 indicator LEDs, one green and one
yellow per jack, are mounted on the front panel of the patchbay. Two rows of 32 9-pin female
subminiature-D (DE9) connectors are mounted on the rear panel of the patchbay. A bantam
audio patchcord inserted in any pair of front panel jacks completes a data connection between a
controller and a remote device connected to the corresponding rear panel DE9 connectors.

Page 4 – Bittree RS-422 64-Port Active Data Patchbay User Guide

Model 422A32-D, with dual, redundant power supplies, features two power indicator LEDs
mounted on the front panel of the patchbay and two “long” 2.0 mm power jacks mounted on the
rear. Meanwhile, Model 422A32A with a single power supply, features a power indicator LED
mounted on the front panel of the patchbay and one “long” 2.0 mm power jack mounted on the

1.3 Powering the Patchbay

Depending on the Model, the Bittree RS422 Active Data Patchbay is shipped with either one or
two power supplies. There are specific grounding and current handling requirements that the
power supplies must meet. Although you could power your patchbay with any power supply that
meets the requirements detailed in the Specifications section (section 4) of this document, Bittree
strongly recommends that you use only Bittree-supplied power supplies to power your patchbay.

To ensure uninterruptible operation and unmatched reliability, Model 422A32-D features dual,
redundant power supplies and automatic internal power switching in case of anomalous events.
Dual power indicator lights on the front panel provide complete status information on both
power supplies and the patchbay’s power bus. Under normal circumstances, when both power
supplies are in good operational condition and powered-up, the patchbay draws its power from
the primary supply, “P1,” which is the supply plugged into the rightmost power jack on the rear­panel. If for some reason the primary supply stops supplying power, the patchbay automatically

Page 5 – Bittree RS-422 64-Port Active Data Patchbay User Guide

and seamlessly switches over to the secondary supply, “P2,” which is plugged into the second
power jack. The switch-over operation is transparent to the user; continuous operation of the
patchbay is maintained.

Table 1 below describes the possible the states and meanings of the two power indicator LEDs,
“L1” and “L2,” which are mounted on the front panel.

Table 1 – Explanation of the states of the two power indicator LEDs

NOTE: If you experience a power indicator LED color combination that is not listed in Table 2,
then the patchbay may possibly be exhibiting an internal fault. Please call Bittree Customer
Service for further assistance.

If you ordered Model 422A32 with the single power supply, your patchbay will still function but
will not have the benefit of a redundant power supply. Continue reading for information and
instructions pertaining to patchbays with either dual or single power supplies.

The DC power plug of the power supply(s) is equipped with a threaded cowling to ensure that,
once installed, it will stay securely plugged in – even if the power supply cable is accidentally
tugged. After plugging the DC power plug into the DC power jack on the rear panel of the
patchbay, screw the threaded cowling clockwise until finger-tight.

TECHNICAL NOTE: This patchbay employs a special “long” power jack, specifically designed
for use with a 2.0 mm inner-diameter, 12 mm long power plug with a locking threaded cowling.
Standard length 2.1 mm power plugs will not make good contact with this power jack.

The 120 Volt AC power plug of the power supply is a three-prong AC power plug that includes
an earth-ground terminal. Bittree recommends that this AC power plug only be plugged into AC
outlets that have been tested and proven to have a true earth-ground connection. Furthermore, if
you are planning to interconnect and patch between more than one RS422 Active Data Patchbays,
please ensure that all the patchbays are connected to a common earth-ground circuit (e.g., by
plugging them all into the same power strip). This ensures that a common ground potential is
established between the different patchbays and the signals are interpreted correctly.

Page 6 – Bittree RS-422 64-Port Active Data Patchbay User Guide

After inserting the AC power plug of the power supply into a grounded 120 Volt AC power
outlet, the green power indicator LED on the front panel of the patchbay, shown in Figure 1,
should light, confirming that the patchbay is powered up. If this does not happen, try a different
AC power outlet. Also please ensure that the DC power plug is properly and completely inserted
into the power jack on the rear panel of the patchbay, and that its threaded cowling is completely
screwed in. If all the above is verified, and the green power indicator LED on the front panel
fails to light-up, please contact Bittree Customer Service.

2. Connecting the Patchbay

2.1 Rear Panel DE9 Connections

Once the Bittree RS422 Active Data Patchbay is powered up, and the green power indicator LED
on the front panel is lit, you are ready to connect controllers and remote devices to it.

Use DE9 male-to-male patch cables to connect controllers and remote devices to the female DE9
connectors on the rear panel of the patchbay. NOTE: Only devices that conform to the Sony

“Protocol of Remote 9-Pin Connector” communications protocol should be connected to this
data patchbay.

This patchbay is designed to mount in a
standard rack, which limits the width of its
chassis to 17.5 inches. On the other hand,
the patchbay is designed to accommodate
the industry-standard two rows of 32
connections. Therefore, the resulting small
distance between adjacent DE9 connectors
on the rear panel may preclude the use of
cables with standard-size DE9 connector
hoods. For this reason, Bittree has designed
a special narrow connector hood, the DE9
Slim Hood shown in Figure 2, which allows
users to fit up to 32 connectors in each row
and take advantage of all 64 patchbay ports.
The DE9 Slim Hood is easy to assemble,
comes with a rugged tie-wrap strain relief
to ensure solid connections, and features slotted thumb screws for maximum convenience.

TECHNICAL NOTES: For standard, one-to-one controller to remote device connections, your
DE9 cables must interconnect all pins of the DE9 plugs at each end, in a “straight-through”
configuration (i.e., they must connect all corresponding pins of the two DE9 end plugs). The
pins that are absolutely required to complete a proper bi-directional connection between a
device and the patchbay are pins 2, 3, 4, 6, 7 and 8. In addition, the patchbay also routes pin 5
of the DE9 connectors, which carries the PRIORITY signal on some Sony devices. Please do not

use a null modem cable, or any other cable that “crosses pins” from one side to the other.

Figure 2 – The DE9 Slim Hood Plug

Page 7 – Bittree RS-422 64-Port Active Data Patchbay User Guide

If you would like to daisy-chain devices through the Bittree RS422 Active Data Patchbay, you
may have to use special DE9 cables, with pins 2 and 7 disconnected, to connect the output
remote DE9 ports of the remote devices. This is because certain popular devices, such as the
Sony DVW-M2000 Digital Videocassette Recorder, internally connect drivers at both differential
pairs of pins (pins 3-8 and pins 7-2) of their second, output remote DE9 connector, which is
commonly used to daisy-chain devices in broadcast mode, so that multiple remote devices can be
controlled by a single controller. This practice is in breach of the RS422 protocol, to which the
Bittree patchbay conforms. Therefore, to make the system work correctly, connections between
the second, output remote DE9 connector (labeled REMOTE IN/OUT in the Sony DVW-M2000)
of one of these devices and the patchbay must be accomplished with these special DE9 cables
that do not connect pins 2 and 7 of the end DE9 plugs.

2.2 Front Panel Patchcord Connections

This data patchbay is a “normaling” patchbay. Therefore, devices connected to vertically
aligned DE9 connectors are connected to each other by default, in the absence of a patchcord.

Use standard 3-conductor bantam audio patchcords to connect pairs of jacks on the front panel.
Connecting jacks on the front panel completes data connections between devices connected to
the corresponding DE9 connectors on the rear panel. When a patchcord is inserted into a front
panel jack, the default normaling connection of that jack is broken, and the data is rerouted
through the patchcord.

3. Verifying and Diagnosing Connectivity

The Bittree RS422 Active Data Patchbay includes circuitry to sense and appropriately auto­configure its rear panel DE9 ports, according to whether a controller or a remote device is
connected. The auto-configuration process relies on signals that exist at the DE9 connectors of
the connected devices, so these devices must be powered up and configured in the correct remote
mode (“Master” or “Remote”). After the devices connected to the patchbay are correctly
configured, the auto-configuration process is accomplished almost instantaneously, in human
time scale (completed in under one tenth of a second).

3.1 Verifying Connectivity

The Bittree RS422 Active Data Patchbay includes connection-status indicator LEDs designed to
help you verify connectivity or even diagnose connectivity problems, in the unlikely event that
they occur. Two indicator LEDs, one green and one yellow, are mounted above or below each
bantam audio jack on the front panel. A simplified schematic circuit diagram of a vertical slice
of the patchbay (side view), including two front panel jacks and two rear panel DE9 connectors,
is shown in Figure 3.

Page 8 – Bittree RS-422 64-Port Active Data Patchbay User Guide

Figure 3 – Schematic circuit diagram of a vertical slice of the patchbay

As shown in Figure 3, the green LED of each jack is connected to the signal line driven by pins 3
and 8 of the corresponding rear panel DE9 connector. On these pins a controller sends its
periodic hailing command when searching for a connected remote device. Therefore, when a
controller is connected to a DE9 port, the green LED of the corresponding jack on the front panel
starts flashing, indicating that the controller has been successfully connected and is searching for
a remote device. Simultaneously, the green LED of the other jack, located vertically above or
below the first jack, will start flashing if there is no patchcord plugged into the first jack. This is
because the internal normaling connection carries the controller’s commands to the second jack.
If the first jack had been connected to a different jack with a patchcord, then the green LED of
that jack would flash, verifying that the controller’s commands are reaching that jack, and
therefore also the rear panel DE9 connector corresponding to that jack.

The yellow LED of each jack is connected to the signal line driven by pins 2 and 7 of the
corresponding rear panel DE9 connector. A remote device responds to the controller’s
commands on these pins. A remote device, however, will not send any data on these pins until it
recognizes an incoming command on pins 3 and 8. Therefore, when connecting a remote device
to a DE9 connector of the patchbay that is not patched to a controller (either by an internal
normaling connection or by a patchcord), the yellow LED of the corresponding jack will not
flash. It will only start flashing when a controller is patched to that remote device, indicating
that the remote device is receiving the controller’s commands and is responding to them. At that
time, the yellow LED of the jack that the remote device is connected to and the yellow LED of

Page 9 – Bittree RS-422 64-Port Active Data Patchbay User Guide

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.

3.2 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.
