Introduction
oadRunner from MUSICAM USA contains the latest in
technologies to bring you the best possible combination of
features and performance available from any portable codec.
Inside its rugged but lightweight enclosure, the RoadRunner contains a
full-featured monaural audio mixer with two microphone inputs and a
third input switchable between microphone and line levels. The analog
audio section also contains a wide array of outputs: two individually
adjustable headphone outputs, plus two unbalanced and one balanced
line level output.
RoadRunner’s digital section contains the widest selection of
compression algorithms available in any portable codec. RoadRunner’s
premier coding algorithm is MUSICAM, MUSICAM USA’s fully
compatible enhancement to the ISO/MPEG Layer II encoding standard.
Industry standard ISO/MPEG Layer III as well as G.722 are also
included. RoadRunner can send and receive up to 20 kHz monaural
audio transparently over digital transmission systems and is compatible
with more codecs than any other similar device. RoadRunner can send
the same audio program to two locations simultaneously. RoadRunner
also contains ample memory to support upgrades to its algorithm suite
and operating system as developments and improvements occur. You
can even make software upgrades in the field, without having to return
the RoadRunner to the factory.
RoadRunner also contains powerful ancillary data features that enable
bi-directional RS232 ancillary data, up to 4 relay contact closures and
far-end remote control when connecting to another compatible codec.
These ancillary data features are available with all algorithms except
G.722. In addition, the powerful Logic Language offers a large selection
of automated functionality programming that is unavailable from any
other manufacturer.
RoadRunner offers more connection options than any other portable
codec. With a plug-in ISDN terminal adapter (RoadRunner’s standard

configuration), RoadRunner can connect directly to another ISDN codec
at bit rates from 56 to 128 kb/s. RoadRunner also accepts any of the
digital interface modules available from MUSICAM USA, and can be
used over any digital facility that accepts V.35, X.21 or RS422 interfaces,
in addition to ISDN.
RoadRunner’s built-in auto-dialer can be used to make all connections
when using any one of MUSICAM USA’s available ISDN terminal
adapters. RoadRunner’s speed dial directory holds up to 256 entries.
Each entry not only holds the numbers to dial, but also all configuration
and connection information, making the RoadRunner easy to use with
any connection type.

Key Features
oadRunner is a complete package. It is housed in a rugged case
and includes a foldaway handle. The complete RoadRunner
package weighs less than 9.5 pounds (4.3 kg). Inside the
RoadRunner case is a full featured 3-channel monaural audio mixer, an
18-bit A-to-D converter, a multi-algorithm codec, a slot for available
plug-in digital interface device (an ISDN terminal adapter is supplied
as standard), an auto-dialer, international AC and DC power supplies,
and a powerful command processor. If you choose, you can connect
your RoadRunner to any digital transmission system through available
ISDN, X.21, V.35 or RS422 digital interface modules.
RoadRunner uses state-of-the-art compression technologies to provide
bi-directional broadcast quality monaural audio over a single 56 or 64
kb/s line. In addition, the RoadRunner can provide bi-directional 20
kHz monaural audio transparently over a single ISDN line at 112 or 128
kb/s. Ancillary data is supported at all bit rates with any MPEG
algorithm.
RoadRunner is easy to use. The RoadRunner front panel controls have
been kept to a minimum, are simple to use, and are clearly labeled. The
front panel controls include mixing levels for three inputs (two
microphone and one switchable mic/line) and individual local and
return level adjustments for two separate headphone outputs.
All audio connections are made through industry standard connectors,
logically located on the front and rear panels. Two balanced XLR
microphone inputs are located on the front panel, as are two standard
¼” headphone jacks. An additional balanced input, switchable
between microphone and line levels, is located on the rear panel. Also
on the rear panel is an XLR balanced line level output and two ¼”
unbalanced local and return audio outputs, ideal for PA feeds,
recording, etc.

The RoadRunner can be equipped with any of the Digital Interface
Modules available from MUSICAM USA. Available modules include
internal Terminal Adapters (with or without built-in NT-1), V.35, X.21,
RS530 or RS422.
Front panel indicators include Power, On line, Norm (signal level) and
Clip (over level). There are also four Cue LEDs indicating the state of
the internal relays. The front panel keypad can be used to access all
functions of the RoadRunner and built in Terminal Adapter, and is also
used as the dial keypad. A backlit display with adjustable contrast
provides menu, maintenance and dialing displays.
Since RoadRunner features and audio quality are implemented in
software, rather than hardware, the RoadRunner can be upgraded in
the field should improvements become available. Software can be
downloaded directly from our Web Site (www.musicamusa.com) or we
can send you an upgrade kit. This prevents your RoadRunner from
becoming obsolete.
CODEC Compression Algorithms
There are currently three coding algorithms used in the RoadRunner.
Each has its advantages and disadvantages. Which algorithm you use
depends on a number of factors, including desired audio quality, delay
and compatibility with other codecs.
ISO/MPEG Layer III
ISO/MPEG Layer III can provide full duplex, 15 kHz monaural audio
using only one 56 or 64 kb/s ISDN ‘B’ channel. When using 112 or 128
kb/s, transparent 20 kHz monaural audio is possible. The inherent
drawbacks of this algorithm are the long coding delay times and poor
cascading characteristics. In addition, post processing may highlight
some artifacts.
MUSICAM and ISO/MPEG Layer II
The premier coding algorithm used in RoadRunner is MUSICAM,
MUSICAM USA’s encoding enhancement to the ISO MPEG Layer II
algorithm. MUSICAM encoding is fully compatible with all MPEG
Layer II decoders, and since the enhancements area part of the encoder,
any Layer II decoder will sound better when connected to a

RoadRunner USERS GUIDE

RoadRunner. MUSICAM can deliver full duplex, 10.5 kHz monaural
audio on one ISDN ‘B’ channel. When using 112 or 128 kb/s,
transparent 20 kHz monaural audio is possible. Although a narrower
bandwidth at 56 and 64 kb/s than MPEG Layer III, audible advantages
are higher transparency, lower delay, less noticeable artifacts and better
results when cascading. At 112 and 128 kb/s, MUSICAM offers
transparent monaural audio and better cascading than either standard
ISO/MPEG Layer II or Layer III.
G.722
G.722 is one of the earliest audio coding algorithms to be standardized.
G.722 is a relatively simple algorithm based on ADPCM (Adaptive
Predictive Pulse Code Modulation) offering full duplex, 7.5 kHz audio
over a single ‘B’ channel. The essential advantages of G.722 are its
compatibility with most other codecs and very low delay times. The
main disadvantages are its limited audio fidelity, poor signal-to-noise
ratio and poor cascading.
Broadcast Capabilities
The RoadRunner can be configured to send the same audio program to
two different locations simultaneously. In addition, the RoadRunner’s
decoder can receive the return audio from both locations, and you can
easily switch to monitor the return audio from either location.
You can use any supported algorithm, and can even use different
algorithms for the send and return audio. For example, a typical
application involves sending high quality Layer III audio to the studio
from the remote location, but low delay G.722 can be used for the return
audio.
Ancillary Data
A bi-directional RS232 data path is provided for end-to-end ancillary data
communications when using any MPEG algorithm. Baud rates up to
38,400 are supported.

Unpacking and Installing
our RoadRunner comes with an AC line cord and an RJ-45
jumper cable if an ISDN terminal adapter is installed. An
appropriate interface cable, available from MUSICAM USA, may
be required if a non-TA module is installed. An optional carrying case
is available.
Unpack your RoadRunner and plug it in to an appropriate power
source. Please note that the RoadRunner has “World” AC and DC
power supplies, and can be used anywhere without changing voltage
settings. RoadRunner can operate in any position, and may be stacked
or shelf mounted if desired. However, note that RoadRunner is fan
cooled, and the rear mounted fan should not be blocked.
Your RoadRunner is shipped to you in Loopback Mode. When in this
mode, you can test all audio input and output connections. When your
RoadRunner is in the loopback mode, and all audio connections have
been made properly, you should hear any audio input to the
RoadRunner at the output of the RoadRunner. Please remember that
for normal operation, the RoadRunner must not be in loopback mode.
RoadRunner Connections
RoadRunner‘s connection to the digital transmission medium is made
through a Digital Interface Module (DIF). The RoadRunner supports
one digital interface module that plugs into a slot in the rear panel.
Two types of DIFs are available, Terminal Adapter (TA) and non-TA.
TAs connect directly to your ISDN line and allow dialing directly from
the RoadRunner keypad. Non-TA type modules can connect to
external terminal adapters or most other digital facilities, such as
dedicated lines, fractional T1 or satellite systems through appropriate
interfaces.

MUSICAM USA offers three different TA modules, the TA101, TA201
and TA301. The TA101 and TA201 both provide an ‘S/T’ interface and
require an external network interface device (NT-1) for use in North
America. Elsewhere, the NT-1 is provided by the phone company, and
an external NT-1 is not required. The TA301 provides a ‘U’ interface
through its built-in NT-1 and therefore can be used only in North
America.
Connect the ISDN line to your internal terminal adapter (if so
equipped). Be sure that there are no alarm conditions present on the
terminal adapters or the NT-1. There should be no flashing LEDs or
other alarm indications for proper operation. The TA201 and TA301
terminal adapters have sanity LEDs that can be observed from the back
of the RoadRunner. The green LED must be solid ON for proper
operation. If using an external NT-1 with your terminal adapter, the
‘U’ interface (the wall connector) requires a 2-conductor cable. The
‘S/T’ interface (the RoadRunner side) requires an 6-conductor cable.
Two non-TA digital interfaces are also available for the RoadRunner.
The DIF101 interface is used for connecting transmission systems using
X.21, RS422, RS449 or RS530 interfaces. The DIF102 interface connects
to transmission systems using the V.35 protocol.
All audio inputs and outputs are through industry standard connectors
located on the front and rear panels. Two balanced XLR microphone
inputs are located on the front panel as are two standard ¼” headphone
jacks. An additional balanced input, switchable between microphone
and line levels, is located on the rear panel. Also on the rear panel is an
XLR balanced line level output for received audio from the far end unit
and two ¼” unbalanced local and return audio outputs to feed
recorders, PA systems, etc.
The four relay outputs and optically isolated inputs are accessed
through the DB-25 connector, and there is a DB-9 connector for
ancillary data, remote control and software upgrades. Connectors for
AC power (100-240 VAC, 50/60 Hz) and 12 VDC power are also located
on the rear panel, as is the power switch.

accordingly.
Mic/Line mixing is accomplished using the three input level controls
located on the front panel. When audio is present, adjust the levels so
that the green ‘NORM’ indicator illuminates and the red ‘CLIP’
indicator does not. It is recommended that the input level be turned
down if an input is not connected.
Two sets of headphones with ¼” jacks can be used without adapters.
When stereo headphones are used, the output will be monaural, to both
ears. Do not use monaural headphones with 2-conductor plugs. The
audio source to the headphones, local or return audio, is adjusted using
the two monitor level controls located above each headphone output.
Level adjustments for each headphone are independent.
Balanced Line level return audio (audio from the far-end) is available
through an XLR connector, and unbalanced line level local and return
audio is available through two ¼” phone jacks. All output levels are
fixed at 0 dBu relative to input levels (no insertion gain/loss).
A 9-pin connector for RS232 ancillary data, remote control and software
maintenance is included, as is a 25-pin connector for the four optically
isolated inputs and relay outputs. In addition, one slot can hold any of
the plug-in digital interface modules available from MUSICAM USA.
Available modules include ISDN Terminal Adapters, RS422, X.21, and
V.35 interfaces. Although primarily an ISDN device, you can also use
the RoadRunner with other digital transmission systems, such as
Switched-56, dedicated lines, fractional T-1 and satellite systems using
the appropriate digital interface module.
The RoadRunner can be used with 12 VDC or AC power. The universal
AC power supply needs no jumpers, and works with 94 - 250 VAC, 50
or 60 Hz. Power consumption is approximately 40 Watts. Please note
that the RoadRunner does require forced-air cooling, and that the rear
mounted cooling fan should not be blocked.
The RoadRunner has a rich set of remote control commands that allow
you to control it from an attached terminal or computer. A separate
RoadRunner Remote Control Manual is available from MUSICAM USA
upon request.

Installing the Digital Interface Module
A digital interface module is required to use your RoadRunner with a
transmission system. Only one DIF module can be installed in the
RoadRunner at a time. If you are using a DIF101 or DIF102 module for
RS422, X.21 or V.35 interfaces use the appropriate cables, available from
MUSICAM USA.
All DIFs are installed in the slot in the rear of the RoadRunner. You
should make certain that the module is installed correctly, not forced
and has been securely fastened using the provided screws. You should
not attempt to operate the RoadRunner if the DIF has not been properly
installed and secured.
Once installed, the DIF module and interface type must be selected on
the RoadRunner menu for proper operation:

RS422/RS449/RS530 and X.21 Using the DIF101 Digital
Interface
The RS422 interface specification defines only the electrical voltages at
the interface and leaves the pin-out and meaning of the pins to the
hardware designer. The RS449 interface specification utilizes the
electrical specifications of RS422 but specifies a mechanical connector.
RS449 equipment is therefore electrically compatible with the
RoadRunner RS422 interface when an appropriate adapter cable is
used. RS449 also specifies numerous control signals besides clock and
data, which are not used by the RoadRunner. The RoadRunner RS422
interface pin-out is specified in Appendix A.
The RS422 interface also has a separate clock for the transmitted and
received data. The RS422 interface can also echo the transmitter clock.
If the terminal equipment clocks the encoder data with the echoed
clock, the RoadRunner may be located up to 4000 feet (1219 meters)
from the terminal equipment without concern for encoder-to-clock
skew.
The X.21 (also known as RS530) interface specification is, in general, a
very complex specification. The general specification allows a
mechanism for communication between the customer equipment and
the network. This communication path can be used for things such as
dialing. A sub-set of the specification, called the leased circuit, used
here, restricts the interconnection to only clock and data and a very
simple control signal. The mechanical connector required is the DB15
with the pin-out specified in Appendix A. The electrical specification
for X.21 is identical to those of RS422. The X.21 interface has only one
clock for both transmit and receive signals.
Since the X.21 uses the RS422 electrical interface, the RoadRunner can
use the same connector for both interfaces. In the case of the X.21
interface, the single clock is used internally for both transmit and
receive timing. To change the hardware configuration of the DIF101
interface card between X.21 and RS422/RS449, change the position of
jumper J4 on the interface module. The jumper on positions 1 and 2
sets X.21 operation, and when on positions 2 and 3, the card is set for
RS422/RS449 operation.
Once the DIF101 module is installed, select the appropriate interface
type from the RoadRunner menu:

RoadRunner USERS GUIDE
13
<Maint><Dig I/F><Type><type>
where type can be either X.21, X.21XTA or RS422.
Select RS422 when connecting the RoadRunner to any RS422 network
interface. When connecting to any X.21, RS449 or RS530 interface, select
X.21XTA if the external network interface device recognizes a change-
of-state of the DTR/CON line. This enables the RoadRunner to
terminate the connection when you press the END button. Otherwise,
select X.21 as the interface type.
V.35 Using the DIF102 Digital Interface
Each interface defines a voltage level for each of the signals. In the case
of V.35 and X.21, a connector type is defined as well. The large,
rectangular block connector defined in the V.35 specification is not used
by the RoadRunner because of its size. Instead, a smaller DB15
connector is used. In the case of the V.35 interface, the RoadRunner
conforms to the electrical specification but requires an adapter cable to
convert the DB15 connector to the connector specified in the V.35
specification. The connector and the pin-out chosen for the V.35
interface in the RoadRunner are a common deviant found in many
systems. An adapter cable is available from MUSICAM USA or
distributors, or can be made following the diagram found in Appendix
B. It is important to remember that V.35 has a separate clock for
transmitted and received data.
Once the DIF102 module is installed, select the appropriate interface
type from the RoadRunner menu:
<Maint><Dig I/F><Type><type>
where type can be either V.35 or V.35XTA.
When connecting to any V.35 interface, select V.35XTA if the external
network interface device recognizes a change-of-state of the DTR/CON
line. This enables the RoadRunner to terminate the connection when
you press the END button. Otherwise, select V.35 as the interface type.

Elsewhere, the service provider supplies the NT-1.
Since every country requires slightly different ISDN control and
signaling information, the TA101 TA requires different ROM chips for
different countries. If you have specified the country in which you will
be using the RoadRunner when ordering, your TA101 will have the
correct ROM chip installed. Please check with your local distributor,
CCS Europe or MUSICAM USA if you will be taking your RoadRunner
to foreign countries. Configuring the TA101 is discussed in later
sections.

Elsewhere, the service provider supplies the NT-1.
The TA201 is pre-programmed with the ISDN configurations for all
countries, and can be used everywhere without the need for changing
