Serialtest^® ComProbe: Serial Data Analyzer & Protocol Sniffer

Serialtest ComProbe is a PC-based analyzer for passively monitoring or actively testing both synchronous (sync) and asynchronous (async) serial data communication circuits and networked equipment. The product offers an economical solution for debugging, testing, and troubleshooting equipment, circuits, and software applications. Typical test applications include: utility meter reading, railroad signal and switch monitoring, PC based control, bank ATMs, lottery and gaming, and credit authorization.

Serialtest ComProbe captures and analyzes data bytes, control signals (modem leads), and data communication protocol information—all the information required to troubleshoot data errors, protocol problems, control signal problems, byte errors, and timing problems. It also transmits data bytes, strings, and files, which enables users to simulate a "live" operating environment.

Serialtest ComProbe decodes monosync, bisync, HDLC, SDLC, X.25, SNA, frame relay, PPP, SLIP, and TCP/IP protocols. The analyzer tests synchronous data circuits at speeds up to 64 Kbps, and asynchronous circuits at data rates up to 38.4 Kbps. Data is decoded at the frame, byte and bit levels, thus enabling users to rapidly detect and isolate even the most minute and intermittent communication protocol related problems associated with data communication products, applications, and networks.

Serialtest ComProbe runs on any Windows XP compatible PC. The RS-232 ComProbe adapter (included with the product) connects the host PC, via the parallel printer port, to the circuit under test. RS-422, RS-485, RS-530, V.35, and other specialized interfaces are supported through the use of optional converters.

Serialtest ComProbe includes software, a Quick Start Guide, a ComProbe RS-232 adapter, a "Y" ribbon cable, and either a 120 volt (STC2X) or 230 volt (STC2X-230) power supply.

Serialtest ComProbe is an indispensable test tool for data communication product developers, network integrators, network troubleshooters and field service technicians. The protocol analyzer enables shorter and less costly development intervals for data communication equipment and applications, faster and more efficient data network installations, and improved mean-time-to-repair following equipment and network outages.

Connect the ComProbe's attached cable to the parallel (printer) port of the PC containing the Serialtest ComProbe software. Connect the single-ended side of the "Y" cable to the ComProbe adapter, and connect each side of the double-ended side of the "Y" cable to the circuit to be tested.

Serialtest ComProbe is part of the Frontline Test System (FTS) family of data communication protocol analyzers and testers, each of which incorporates the protocol-decoding engine as its core element. Serialtest dramatically reduces the time spent searching through hex dumps by presenting data in a highly organized, easy to read format. Users can pinpoint errors in seconds, rather than hours. FTS protocol analyzers employ a common user interface, offer protocol decoding at the bit level, and enable the rapid development of custom decodes for proprietary protocols and extensions to existing protocol decoders through the FrameDecoder option. The common user interface shortens the learning curve for engineers working with multiple protocols or topologies such as serial and Ethernet.
