Dear Sir/Madam, We are pleased to hear of your continued prosperity. Thank you very much for your continued patronage of our products. We are pleased to announce that we have updated the firmware version of our "Sound Level Meter LA-1440/4440" to Ver.2.10. This update will improve the data transfer speed when communicating using RS-232C or USB with the Sound Level Meter LA-1440/4440.
Customers who wish to upgrade the firmware of their LA-1440/4440 sound level meter should contact their assigned sales office or distributor. This firmware upgrade is free of charge. Please note that the firmware upgrade will require us to take your sound level meter back to us.
Applicable models
- Integral-averaged sound level meters LA-1440 and LA-4440
(Firmware version: Ver.1.20 or earlier)
Improvement function
Data transfer speeds using RS-232C and USB are improved. For example, the transfer time when transferring large amounts of trend data recorded in AUTO 3 mode, etc., to a PC is improved. When using the free software "Memory Read," the memory data transfer time becomes 10 to 100 times faster when connected via USB.
Note
This version update improves communication functionality. There are no changes to other features.
Transfer speeds vary depending on the PC's capabilities and operating environment.
LA-1410 does not include the improved communication function, so there is no need to upgrade.
Customers who do not use the communication functions of the LA-1440/4440 do not need to upgrade their software.
