The Analyst RS422/RS232 Tester allows users to quickly and easily isolate and identify RS422 and RS232 interface problems - whether testing cable runs between floors or between buildings, verifying RS422/RS232 signal paths, or chasing down an RS422 to RS232 adapter problem.

Key Features

  • Easy, simple and reliable to use for both experts and non-experts alike.

  • Compact, hand-held device with an easy-to-read four-line x 40-character display, an eight-key keyboard, and separate RS422/RS232 connectors.

  • Simple and intuitive for the technical and non-technical alike.

  • Anyone can perform testing in seconds that once took 30 minutes and required specialized knowledge.

  • Switch-selectable beween RS422 or RS232 for chasing down RS422 to RS232 adapter problems.

  • Quickly identify cable wiring errors at the press of a button:
         Swap transmit and receive lines (RS422/RS232)
         Reverse transmitter output polarity (RS422)
         Reverse receiver input polarity (RS422)

  • Confirm without a doubt that two cable ends are connected to the same cable.

  • AC-powered with optional external battery pack.

  • Easily and quickly check system baud rate and parity settings.

  • Four-line x 40-character liquid crystal display.

  • Eight-key keyboard with a rotary knob.

The Analyst RS422/RS232 Tester is ideal to use in remote production setup, new studio builds or facility upgrades, or in maintaining existing facilities and systems.




Fuji Photo Film Chooses DNF Controls' Analyst RS422/RS232 Tester to Streamline Production Machine Communications

Greenwood, S.C.-based Fuji Photo Film, Inc., the North American manufacturing and R&D headquarters of the Fujifilm family of companies, has purchased The Analyst RS422/RS232 Tester to help streamline communications between production machines. 

They were looking for an effective tool that could help them troubleshoot communications problems between our two production machines and quickly determine which communications link was causing the problem. The Analyst works with both RS422 and RS232 control interfaces, and having a single device that can analyze both types of serial protocols is a great benefit. It was the only product out there that met their requirements.

Fuji Photo Film's production machine sends serial data from a Programmable Logic Controller (PLC) to a thermal printer that only communicates with RS232 cable. Because the cable length between the devices is greater than 50 feet, the PLC sends the data via RS422 cable to an RS422/RS232 converter mounted on the thermal printer. If the two devices fail to communicate properly with each other, it could potentially take hours to identify the problem.

RS232 and RS422 control interfaces are standard on most equipment found in broadcast or production facilities, as well as on other devices like Fuji's PLC and thermal printer. Because these interfaces can be so time-consuming and frustrating to troubleshoot, DNF Controls designed The Analyst RS422/RS232 Tester as an easy-to-use, intuitive, troubleshooting tool that enables experts and non-experts alike to separate "what is the problem" from "what is not the problem" quickly. This allows resources to be directed at fixing the real problem, rather than running around in circles.

The Analyst RS422/RS232 Tester allows users to isolate and identify RS422 and RS232 interface problems quickly and easily - whether testing cable runs between floors or between buildings, verifying RS422/RS232 signal paths, or chasing down an RS422-to-RS232 adapter problem.
