6.1 Realtime Cabling, Output Protocols & Viewer Software

Quick Summary: Local realtime reporting delivers an instantaneous, verbatim English translation of spoken proceedings directly to the computer screens of judges, attorneys, and litigants. Mastering physical RS-232 multi-drop distribution cabling, standalone Wi-Fi routing, asynchronous 8-N-1 serial framing, output protocols (CaseView, Bridge, LiveNote, Denoto), and client viewer workflows guarantees seamless delivery and safeguards privileged attorney work product.

The Architecture of Local Realtime Delivery

Realtime court reporting is the pinnacle of the stenographic profession. The RPR job analysis lists CAT realtime features, wired and wireless connections, and clients' viewing platforms among its Domain 1 (Technology and Innovation) topics. In high-stakes litigation, antitrust trials, and complex commercial depositions, litigators and judicial officers rely on live steno feeds to formulate cross-examination questions, rule on evidentiary objections, confirm exact witness phrasing, and annotate pivotal testimony as it is uttered.

Local realtime delivery operates on a clear separation of operational roles:

1. The Translation Source (Reporter's Workstation): The court reporter strokes stenographic chords on a computerized writer. The writer transmits raw stroke packets across a wired or wireless interface to the reporter's Computer-Aided Transcription (CAT) laptop. The CAT software's translation engine matches steno strokes against personal, job, and system dictionaries, instantly compiling an English transcript complete with line numbers, page coordinates, and speaker designations.
2. The Output Broadcast Engine: The CAT software routes the translated English text through an export filter configured with a specific litigation support protocol (such as CaseView or Bridge) and directs the data stream out through physical serial ports, virtual Bluetooth COM ports, or local network sockets.
3. The Litigation Support Viewer (Client Terminals): Judicial officers and attorneys run specialized client viewer software (e.g., LiveNote, Bridge, CaseViewNet) on laptops or tablets. These applications receive the text stream, render it in a customized viewport, and provide local search, split-screen review, and private note-taking tools.

Physical Cabling & Distribution: Multi-Drop Serial Splitters & Hardware Hubs

Before the advent of local wireless networking, physical copper serial cabling was the sole medium for courtroom realtime distribution. Where a court or facility restricts wireless use, wired distribution is still the practical choice.

The Multi-Drop Serial Configuration

Standard RS-232 is fundamentally an asynchronous, point-to-point communication standard designed for exactly two devices: one Data Terminal Equipment (DTE) and one Data Communication Equipment (DCE). Connecting multiple client computers to a single serial port requires a specialized RS-232 Multi-Drop Splitter (often called a distribution amplifier or SmartCable):

• The Master Transmit Line (TXD): Pin 3 (TXD) from the reporter's laptop is wired in parallel to Pin 2 (RXD) on every client terminal connector. Every client receives an identical copy of the outbound steno data stream.
• The Signal Ground Reference (Pin 5): Pin 5 (GND) is shared across all connectors, providing a common electrical ground reference across all connected computers.
• Client Transmit Line Isolation: Standard RS-232 drivers cannot share a common transmit bus. If multiple client computers attempted to transmit across Pin 3 simultaneously, their line driver voltages would collide, resulting in short-circuit conditions, blown serial UART chips, and garbled data. Therefore, the Pin 3 (TXD) conductors on all client cables are physically severed or diode-isolated. Client terminals operate strictly in receive-only mode.

Distance Limitations and Signal Conditioning

The EIA/TIA RS-232-C standard specifies a maximum cable capacitance of 2500 pF, which typically translates to a maximum physical cable length of 50 feet (approximately 15 meters) for unshielded twisted pair wiring operating at 9600 baud. In sprawling ceremonial courtrooms where cable runs from the court reporter's well to the judicial bench and opposing counsel tables exceed 100 feet:

• Low-capacitance, shielded serial cables must be deployed to prevent high-frequency signal attenuation and crosstalk.
• Active serial line drivers or distribution amplifiers with external DC power must be placed inline to regenerate voltage square waves.

[!IMPORTANT] The Receive-Only Rule: Never connect a standard bidirectional null-modem serial cable to a passive multi-drop splitter. If a client computer asserts voltage on its TXD pin while another client is connected, the entire serial bus collapses, locking up every litigation viewer in the courtroom.

Realtime Output Formats and Viewer Compatibility

CAT programs send realtime text in formats that particular viewer programs understand, so setting up a feed means choosing an output format that matches each client's viewer. The product names below are examples; formats, versions, and supported connections change, so confirm compatibility with the CAT and viewer vendors before the proceeding.

Two rules apply whichever product you use:

1. Match the format and settings. A mismatch between the CAT output format (or serial settings) and the viewer produces garbled or missing text.
2. Test before going on the record. Push a sample page to every connected viewer and confirm line numbers, speaker labels, and scrolling.

Configuring Communication Ports, Baud Rates, and Parity

For a litigation viewer to decode incoming steno text, the serial communication parameters on both the transmitting CAT laptop and the receiving viewer terminal must match precisely.

8-N-1 Framing

Serial realtime output commonly uses 8-N-1 asynchronous framing:

• Data Bits = 8: Each byte represents a complete ASCII or UTF-8 character code.
• Parity = None (N): No parity bit is calculated or appended to the byte frame.
• Stop Bits = 1: A single stop bit frames the conclusion of each character byte.

[!WARNING] Framing mismatch: Some older viewer or terminal setups may be configured for 7-E-1 (7 data bits, even parity, 1 stop bit). If your CAT software outputs 8-N-1 while the client viewer is set to 7-E-1, the high-order bit of each byte will be stripped or corrupted, causing vowels with accent marks, punctuation marks, and speaker identifiers to render as garbled punctuation or empty boxes.

Baud Rate Matching

The baud rate defines the data transmission speed in symbols per second (bits per second). Both ends of the serial conduit must be locked to the exact same frequency:

• Older hardwired serial feeds: Often ran at 9600 baud.
• USB-to-serial adapters and virtual COM ports: Commonly support 19200, 38400, or 115200 baud; use whatever rate both ends are set to.

Flow Control Selection

As covered in Section 3.1, software flow control (XON/XOFF) is normally turned off ("None") for binary steno data. If a steno packet contains byte values 0x11 (ASCII 17) or 0x13 (ASCII 19), software flow control interprets them as pause commands, abruptly locking the viewer display. Configure realtime output for hardware flow control (RTS/CTS) or no flow control.

Client Litigation Support Viewer Software Deployment & Testing

Setting up client terminals requires systematic pre-proceeding verification before the judicial officer takes the bench or the deposition is called to order.

Prominent Litigation Support Viewers

• CaseViewNet (Stenograph): Widely deployed in judicial chambers and courtrooms; connects via local serial ports, local Wi-Fi IP sockets, or cloud sessions.
• Bridge / Bridge Mobile (Advantage Software): Highly adaptable; supports Windows, iOS, and Android; features robust real-time search, multi-document navigation, and dynamic updates.
• Other platforms: Some litigation-support and deposition platforms include their own realtime viewers; confirm the format and connection they require.

Pre-Trial Testing & Verification Protocols

1. Loopback Testing: Before connecting client hardware, the reporter should verify their own outbound feed using an internal loopback test. In CAT software, route the output to a virtual COM port pair or the local software IP address (127.0.0.1 / localhost) and run an instance of the viewer software locally. If steno strokes appear on the local viewer, the CAT output engine and protocol formatting are proven functional.
2. Pushing Header & Test Strings: Once client laptops are connected via serial cables or Wi-Fi, the reporter should push a pre-prepared test script (e.g., standard appearance pages and title blocks). Verify that:
   • Line numbers align vertically (lines 1 through 25).
   • Text appears instantaneously with zero perceptible delay.
   • Font pitch and sizing are legible on counsel's monitor.

Viewer Features & Judicial/Attorney Workflows

Litigation support viewers are not mere electronic text displays; they are sophisticated analytical environments tailored for trial advocacy and judicial decision-making.

1. Split-Screen Capabilities

Judges and trial attorneys frequently divide the viewer interface into multiple panes:

• Pane 1 (Live Realtime Feed): Displays newly stroked testimony scrolling upward in real time.
• Pane 2 (Historical Testimony / Prior Deposition): Displays testimony from earlier in the trial, a prior witness deposition, or an electronic exhibit, allowing counsel to compare witness answers side-by-side without leaving the live session.

2. Auto-Scroll vs. Paused Scroll ("Free Scroll")

A critical feature of litigation viewers is the uncoupled viewport buffer:

• When an attorney wants to re-read a question asked ten minutes earlier, they simply scroll up, click a previous line, or initiate a search. The viewer immediately disengages auto-scrolling.
• Crucially, the viewer's background communication process continues receiving and parsing every newly stroked sentence. Strokes accumulate invisibly in the local application buffer.
• Once counsel has completed their review, they click a prominent "Follow Realtime" button (or tap the spacebar/F-key shortcut), and the viewport instantly snaps back to the current live line with zero missing testimony.

3. Rapid Search & Boolean Indexing

Litigation viewers index every incoming word in real time. Counsel can execute complex searches across thousands of transcript lines in milliseconds:

• Boolean Operators: Utilizing queries such as asbestos AND warning NOT label to instantly isolate relevant colloquy.
• Proximity Searches: Searching for terms appearing within a set number of words (e.g., valve w/5 failure).
• Go-To Navigation: Jumping directly to specific page and line coordinates (e.g., P. 42, L. 18) requested by the judge during oral argument.

4. Private Annotations, Issue Coding & Attorney Work-Product Privilege

Attorneys routinely mark up the live transcript during proceedings:

• Color-Coded Issue Highlighting: Assigning specific colors to predefined legal categories (e.g., Yellow for Hearsay, Green for Damages, Red for Impeachment).
• Private Marginal Notes: Typing confidential strategic notes attached to specific transcript lines (e.g., "Ask about maintenance logs on redirect").

[!IMPORTANT] Private annotations: Viewer notes and highlights are generally stored with the attorney's own copy of the viewer rather than sent back to the reporter's CAT system, but confirm how a given product (especially a cloud session) stores them. An attorney's notes can be work product under FRCP 26(b)(3), so a reporter should never access or share a client's annotations.
