I am hoping to use a lcd display to display an error or insriuction after a ticket is scanned at a gate using a usb to ethernet converyer. Any suggestions or resources.
Something like this might work, (and a couple more show up when searching for usb or serial over ethernet on google) but we have never tested such a setup so we cannot guarantee it will actually work.
Yes I saw those but was wondering if this has been tried...evidently not. My concern is powering the lcd from the usb hub.... What is the minimum power needed for the lcd module and what do you recommend as a model number to use in this application.
will I have to regulate the power or will thet work on a range of voltages. I am thinking I will power these throught the blue pair of the ethernet and there may be some voltage drop at 5 v. at a distance so I thought 12v and accept the vo;tage drop at the server end or regu;kate it there.
