What is SI_SCOPE?

Serial monitor allows you to monitor RS232 communications in real time! SI_SCOPE is a comprehensive RS232 analyzer for the PC that is used to debug, analyze, or document serial communications. With SI_SCOPE you can eliminate guess work and quickly diagnose problems by viewing RS232 data and signal changes in real-time from your PC.

SI_SCOPE transforms your PC into a serial monitor without the need of expensive hardware or plug in boards. All that is required is a PC or laptop with two available serial ports running Windows Vista, Windows XP, 2000, ME, 98, or 95. SI_SCOPE utilizes its own 32-bit kernel mode drivers, which are engineered for serial analysis, allowing it to accurately capture and time stamp data from an RS232 line at baud rates up to 921.6 Kbps.

SI_SCOPE can also operate as a serial spy. Spy mode is a software only solution that allows you to view the data flow between any Windows application and the operating systems serial driver. When in serial spy mode SI_SCOPE gives you the ability to debug internal ports and modems on Windows XP and 2000 systems.

How does the RS232 Analyzer work?

In Async mode SI_SCOPE monitors your RS232 circuit by tapping the line with a specially wired passive cable. The communicating devices are connected to the 25 pin head of the passive cable, and the passive cables 9 pin leads are connected to two serial ports of the PC running SI_SCOPE.

The diagram to the left illustrates how the passive cable operates. When RS232 data is transmitted from one device to the other, the data is passively routed into the SI_SCOPE PC while being transmitted to the receiving device.

SI_SCOPE requires two serial ports to display bidirectional RS232 communications. SI_SCOPE can also operate in single port mode to display one side of an RS232 link, operate in dumb terminal mode, or monitor a half duplex RS485 link (requires the use of an RS485 <-> RS232 converter or installation of an RS485 card).

SI_SCOPE's Async mode drivers support Windows Vista, XP, 2000, NT, ME, 98, and 95.

How does Spy mode work?

Spy mode is a software only solution that does not require any special cabling or a dedicated port. In spy mode SI_SCOPE's serial spy driver will insert itself into the Windows driver stack and silently monitor the activity between a Windows program and the standard Windows serial driver. Spy mode will work on any port enumerated by the Windows serial driver including internal PCI modems and USB <-> RS232 converters. Spy mode is supported on Windows XP and 2000 systems.

Is it easy to use?

Very easy! Unlike similar products with cryptic interfaces SI_SCOPE's menu driven architecture requires little or no learning curve. You can be productive with it right out of the box and refer to the manual as needed. Click on the image on the right to view an enlarged view of the interface.

SI_SCOPE Feature List

Async mode support for Windows Vista, XP, 2000, NT, ME, 98, and 95!
Fully configurable UART parameters with support for user defined non standard baud rates.
Capture data in selectable formats including ASCII, EBCDIC, and HEX
Built in breakout box allows real time monitoring of all DCE and DTE control signals. Control signals can also be recorded to the data stream allowing you to analyze where and when signal changes occur.
Line status errors can optionally be recorded into the data stream allowing you to see precisely which device generated the error and when the error was detected.
File Capture option allows RS232 analyzer session to be recorded to disk as it happens. Included conversion program compiles data into a binary (record format included in documentation), ASCII, or documented text file. ASCII format allows for user defined field delimiters for easy integration into third party word processing and spread sheet programs.
Capture file can be automatically archived by SI_SCOPE at a user defined time each day to support environments where SI_SCOPE is running in continuous unattended operation.
Capture file can be saved and reloaded into SI_SCOPE for review at a later time.
Flexible trigger mechanism allows you to activate and deactivate data capture based on incoming data streams (wildcards are supported!)
Popup rulers, ASCII charts, and time cursors provide the tools you need to analyze RS232 data patterns.
Search Engine can scan through captured data for any data pattern, signal change, or line status error.
Time stamps included on all captured data with a 1 millisecond resolution.
Automatic detection and support for NS16550 UARTs.
Supports any 2 user defined port addresses and any 2 IRQs. Shared IRQ multi port cards as well as PCMCIA devices are also supported.
Built in support for USB <-> RS-232 converters.
Included Passive Cable allows for non intrusive bi-directional monitoring of all data and control signals.
Spy mode support for cable free operation under Windows Vista, XP and 2000.
Supports half duplex RS485 communications and 9 bit protocols when used with an RS485 converter.
Comprehensive online manual included in both Windows Help and Adobe PDF format.
When purchased with an optional Active Cable SI_SCOPE allows controlled interaction with the serial line from the keyboard. Send data to one or more devices while observing responses. Please note that the Active Cable is optional. SI_SCOPE comes complete with a Passive Cable for bi-directional monitoring.
When purchased with an optional Active Cable SI_SCOPE's programmable macros allow complicated data strings to be recorded and replayed at the touch of a key. Macros can be sent out one or both ports.

Please note that SI_SCOPE Electronic includes both Async and Spy mode drivers. You will need to build your own cable to use Async mode. The DOS version of the RS232 analyzer is not included in the electronic build.
