I should mention that when I started on this project, I intended to utilize esp-link for both serial devices. I need to connect a DirectLogic DL06 PLC via RS-232, a pool chemical controller ( Chemtrol PC-2100) via RS-485 and a BeagleBone Black to WiFi. Pool Systems AutomationĬurrently I’m working on a Pool Systems Automation project, which happens to fall under both the personal and volunteer categories. Plus, it can be found for “cheap” on surplus, which is a huge bonus for personal/volunteer projects. Its feature set, capabilities and user interface are miles ahead of what I experienced on the W2250 or LES401A. While technically it, too, is EOL, it still has fairly recent firmware releases. I’ve also used a Black Box LES401A with success (I think it’s actually an older re-labeled B&B Electronics unit), but it’s bulky, has just one port, and is Ethernet-only.Įnter the Lantronix PremierWave XN. The MOXA W2250 Ethernet/WiFi devices I still rely upon daily to run HVAC, lighting and energy management in my home “mostly just work” – but are somewhat quirky, and lack great user interfaces (to be fair, these particular units are EOL). I’ve used several solutions in the past, with mixed success. Given that I also live in the modern world, I have a real need to connect to these devices remotely (over the Internet) or to distributed machines (such as VMs) with the need for excess cabling (i.e.
I use a lot of devices that (still) communicate solely via the lowly serial port, whether that be via RS-232C or RS-485.
