IN THIS ARTICLE
In this article we will describe different scenarios for using the HDMI port on a DA70A1 and DA50A1.
The HDMI output is for a remote monitor. It only shows the Display Pages. You cannot access the device's Web Server using the HDMI port connection.
The FlexEdge HDMI models do not support touch screen monitors. But you can connect a USB mouse and/or a USB keyboard. We support the standard Microsoft drivers for mouse and keyboard devices. We do not support any other specialty drivers for these; we do not have a touch screen driver.
The FlexEdge DA70A1 with HDMI has one USB Host port built in. You can use it to connect a USB mouse and/or a USB keyboard. You can connect both to the same USB Host port using a standard USB hub. You can also use most combination mouse/keyboard devices because they typically use an internal USB hub with standard mouse and keyboard devices. (Note: Do not get the USB option sled to connect both. If you wanted both mouse and keyboard, you must use a USB hub and connect them to the same USB Host port.)
The DA50A1 does not have a USB Host port built in. However, you can add one with the USB Host option sled. Then you can connect both mouse and keyboard using a hub.
If you want to connect to the web server, then you need to connect to the FlexEdge using a web client application such as Chrome, Edge, or Safari. You cannot do this on the HDMI port. You must have a TCP/IP connection over Ethernet, Wi-Fi. or cellular.
The HDMI output is designed to work with a standard HD monitor that supports 1080P, which is 1980 x 1080 resolution. You should configure your monitor for 1980 x 1080, and also make sure the Crimson database is configured for the same resolution as well.
There are several other settings lower than 1920 x 1080 available. However, those settings are not really intended for use on the HDMI model in normal operation. The intended use case is to drive a 1080P standard HD monitor.
The database's resolution can optionally be configured for the same resolution as any of our HMI products. This can be useful for some things, such as importing and converting files from other HMI models. While those lower resolution settings are an option, and should work if the monitor supports them, the HDMI enabled models were not really intended for use with low resolution monitors. The intent is to drive a standard HD resolution external monitor. We do not support anything higher than 1920 x 1080 resolution.
It is recommended that you manually configure your monitor for 1080P, rather than depending on any sort of auto-detection options that your monitor may have. These auto-detect mechanisms can behave different, and some may work while others can cause an issue. You might even get an auto mode to work while setting it up, but then you cycle power and it may not behave the same for some reason.
The only other settings are those for the Video Out in the Hardware Configuration section. The Preferred Refresh lets you set the monitor's refresh rate explicitly to 50 Hz or 60 Hz. This setting might be important in locations such as Europe where AC power is 50 Hz. That other setting for Extended Modes is not supported, so leave it Disabled.
