Review: Works with Avigilon / HID Vertex controllers - Used 2 of these to extend the 485 buss from an Avigilon V1000 Embedder controller that normally will not support V2000 ethernet 2 door controllers. I set up a point to point bridge to a building across the street. 250mb connection. Then used V100 door controller with 485 in. Once i set up the host and client then set the correct baud rate they connected. My access card swipes and open time are fast. Good product. They come with a fixed IP address of 192.168.0.6 or .7 no printed instructions. So make Shure you have internet access during you install. Review: Timely delivery, good quality product - I received the product via Express Mail (not courier) ahead of schedule ( good surprises still happen ! ), packaging was very good and included the power supply 5V/1A and an RS232 Cable as well. Logged into the device with no problems, very easy to use interface in it's software setup. Product was shipped via Expedited Mail (not courier) and arrived ahead of estimated schedule, always nice ! Only 1 critique, no information at all in the package in regards to where to get doc's, manuals & the software app that can be used for configuration. Although this is not really needed, it would be nice if a purchaser did not have to "hunt" for that info if bought through desertcart. If bought direct, not a problem as that is all there on the site. ## Features - Dual Serial Device Server: Cpu: Cort ex-M4 120Mhz, Serial RS485 & RS232 to Ethernet Server, 2 Serial Ports: 1 Port is RS232, 1 Port is RS485, 1 RJ45 Ethernet Port.

And is this mac compatible?** A: The device is an adapter. It will convert communication protocols such as RS232, RS422 and RS485 in and outbound into ethernet ( TCP) Packets. MAC's and PC's both use TCP. The software would be created by you. You would need to give a description of your intended use case(s) for a more definitive answer. **Q: Do these support ddns updates so i can get back in after the public ip changes?** A: Not Support. **Q: By using this device, am i able to communicate the compactrio and omron plc?** A: Probably. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works with Avigilon / HID Vertex controllers *by N***N on April 19, 2021* Used 2 of these to extend the 485 buss from an Avigilon V1000 Embedder controller that normally will not support V2000 ethernet 2 door controllers.

I guess the only people that buy one of these already know how to set it up. I have had it for a week and just now got to the web interface so I dont know if it works but progress I am making progress.
