RS-232C/422/485 and TTL Protocol Analyzer “LE-1500R”

LINEEYE Co., Ltd released the new protocol analyzer "LE-1500R", a low-cost analyzer for asynchronous communication of RS-232C/RS-422/RS-485 and TTL (1.8V-5V signal level).



[ Background and Outline ]

Asynchronous communication of RS-232C or RS-485 is still used extensively for the field of control devices or measurement instruments, and a low-cost communication analyzer to analyze problems of those fields has been needed.

The previous model "LE-1500" has RS-232C port and RS-422/485 port but this time LINEEYE Co., Ltd released "LE-1500R" which has TTL measurement port besides those port. With the standard TTL(1.8V-5V signal level) measurement port you can monitor TTL communication without using TTL expansion kit which is needed for TTL monitoring by the previous model LE-1500. While it succeeds the proven online monitor function, simulation function, and BERT (bit error rate test) function, we added more internal buffer memory and SD card/USB flash interface for its storage media. Also we added Wi-Fi function and you can remotely monitor the line from your PC by using Wi-Fi (note: Wi-Fi function is valid only in Japan, USA, and Canada). Besides that, we added a light edition of the optional PC link software (with a little bit limitaion) as a standard accessory. The PC link software offers continuous recording to a PC and conversion from .dt file to .text/.csx file format.

[ Features ]

  1. Measure up to 500Kbps. Speed is freely set to 4 effective digits.
  2. Supports RS-232C/422/485 and TTL monitoring without any options
  3. Auto Save function saves measured data into a SD card or USB flash for long hours.
  4. Back up control for sudden power failure to ensure the logging to a SD card.
  5. Remote connection from PC via Wi-Fi (Note: this function is valid only in Japan, USA, and Canada.)
  6. Automatic measurement by time indication using RTC (real time clock)
  7. Trigger function can control external signal output terminal and user defined LED.
  8. By the simulation function you can transmit registered character line by simple operation.
  9. The small body can be installed on a 35mm DIN rail.
