Setting this up usually requires three devices: 1) a connection to the network (E.g., a router or a switch), 2) the PD, and 3) the PoE injector itself.

You will need new polarizing film to replace the damaged filter. Check the specifications for your printer model and LCD screen size to determine the required dimensions. Many brands sell replacement LCDs, but you can likely find inexpensive generic polarizing film sold in packs on sites like Amazon and AliExpress. Ensure any film you purchase has adhesive already applied. Get your polarizing film here:

Run an exposure test or do a test print if available. The pattern or print should come out crisp and clean when the film is aligned correctly. If issues persist, try re-aligning the film or replacing it if defective.

These devices connect a wireless access point (WAP), PoE lighting, IP camera, or any IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt-powered device (PD) to a network switch. Power is then “injected” into an Ethernet cable. Typically, a PoE injector converts AC to DC to power these low-voltage PoE devices.

Adopts PoE technology that does not conform to the 802.3at/af/bt standard is considered to use passive PoE. Generally, passive PoE devices run on 18 to 48 volts. It is important to note that it may likely cause permanent electrical damage to the device if the wrong voltage is connected.

Conforms to the PoE standard of IEEE 802.3af, IEEE 802.3at, or IEEE 802.3bt is considered to use active PoE. During the initial handshake, if the PoE injector does not receive the proper acknowledgment, it will not power up, ensuring the device’s safety. The typical 802.3at/af/bt PoE voltage is 44 to 57 volts (V) DC.

“A device that adds power to an Ethernet cable for Power over Ethernet (PoE) equipment. Although Ethernet switches are available with PoE capability, millions of regular “non-PoE” switches are in use and continue to be installed. . .”1

A PoE injector usually has two RJ45 ports, one labeled Data In and one labeled PoE/Data Out. Following is an overview of what each of these ports does.

This is the most crucial step to get right. The new film must be precisely aligned in the correct orientation to properly filter light from the LCD. If your printer has an “exposure test” mode, use this to find the optimal angle. Rotate and orient the new film while observing the test pattern until it appears dark and crisply defined.

In addition, they can also be typed by the number of ports they have (e.g., one-port PoE injectors, eight-port PoE injectors, etc.)

Depending upon the output power voltage a PoE injector supplies, it is put into one of three types: 12V, 24V, or 48V. The voltage of a PoE injector must be taken into account as its voltage and the voltage standard of the PoE device must be compatible.

Versa Technology has a line of high-quality PoE injectors that will enable you to couple non-PoE power sourcing equipment (PSE) with PoE PDs.

Carefully detach and scrape off any remnants of the old polarizing film from the LCD screen using a plastic scraper. Be very gentle to avoid scratching the screen. Thoroughly clean all adhesive residue off the display using high % isopropyl alcohol and a lint-free cloth.

With the right alignment marked, carefully measure and cut the new film to size so it can cover the entire LCD screen surface. Leave a small margin of extra film on the edges. Double check measurements to ensure proper fit.

Gently lower the new film onto the screen using your alignment guides. Slowly press down while avoiding bubbles and debris under the surface. If any bubbles appear, gently press them out towards the edges with a soft tool.

Let’s use the example of an IP security camera. The Data In port connects the security camera to the local network, the NVR camera port, or a network switch. If this port is not connected to the security camera, the local network is unreachable.

Power over Ethernet (PoE) delivers both power and data concurrently via twisted pair Ethernet cabling. This technology improves network agility and scalability in efficient and cost-effective ways. There are several types of PoE devices, for example, the PoE switch, PoE splitter, PoE injector, etc. This article focuses on the PoE injector: What is it? What does it work? Are there different types? How is it installed?

With care and patience, the polarizing filter can be replaced successfully, avoiding the cost of a whole new LCD screen. Your resin printer should be ready to resume printing!

This port has two functions: 1) It delivers power to the IP security camera, and 2) it completes the network, so data is transmitted successfully. If this port is not connected to the security camera, it will not power up and will not connect to the NVR/network.

If your printer lacks this mode, you may need to do test prints to dial in alignment. Mark the correct orientation once found.

Many resin 3D printers utilize an LCD screen topped with a polarizing filter to selectively cure resin during printing. If this delicate polarizing film becomes scratched or damaged, it can cause print failures and errors. Thankfully, the polarizer can be replaced in most resin printers without needing to swap out the entire LCD screen assembly. Here is a general guide on how to properly replace the polarizing filter film.

As stated above, these (also called midspan or PoE adapter) are used to make a non-PoE LAN switch port work with PoE devices. A PoE injector is ideal for low-power devices that need to be installed in hard-to-reach places where there are no power outlets available. This affords power with no impact on existing building structures at a minimal cost.
