gweempose Posted December 6, 2023 Share Posted December 6, 2023 I'm looking to pick up some used 2477D dimmers, and I'm wondering if there is a minimum rev. number that I should be looking for? I'd hate to waste my money on an obsolete version of the hardware. Link to comment Share on other sites More sharing options...
IndyMike Posted December 6, 2023 Share Posted December 6, 2023 @gweempose, not sure exactly what you are looking for. I believe all of the 2477D's were dual band. The following link lists I2 and I2CS introductions for the device: http://www.madreporite.com/insteon/Insteon_device_list.htm Beyond that, I ran some testing on my 2477D devices to determine if Smartlabs had removed the "all-on/all-off" broadcast commands. From what I saw, devices with a FW level V.45 did NOT respond to the All-On/All-Off broadcast: https://forum.universal-devices.com/topic/41651-all-on-removed-in-what-firmware-version-of-switchlinc-dimmers/?do=findComment&comment=369748 Not sure if that's what you were looking for...

IM Thanks for the reply! I guess I was just curious if there was some point in the run where they made a signifigant change in the hardware that increased the performance and/or reliability.

IndyMike Posted December 9, 2023 Share Posted December 9, 2023 The I2CS protocol increased security - Incorporated @ FW V.41/ Rev 6.9 in late 2012 (madreporite) Removing the All-on/All-off command seems to have been incorporated @ FW V.45 / Rev 7.8 in the 2016 time frame. Beyond that, there "may" have been power supply capacitor changes to improve durability (similar to the changes in the PLM). I do not have information on that. @Brian His a good source for hardware information on many of the devices. Hopefully he can educate us on any improvements that may have occurred.
