AT-USBC-JB – The In-wall PoE Converter for all Tablet Devices <13″

Welcome to the PoE Texas Manual for the patent pending AT-USBC-JB designed for all tablet devices including Microsoft Surface, Apple iPad (USB-C and Lightning), Samsung Tab, and Amazon Fire that gives you wired Power and Data or wired Power for your USB Type C devices!

The purpose of the manual is to help you quickly and effectively navigate the installation and functions of your new Power Over Ethernet Converter.

Our goal is to make our products as intuitive and simple to use as possible, so we value your feedback and questions directly to us at service@poetexas.com.  Phone +1-512-479-0317.

What’s Inside


  • 1 X POE+ Converter

with optional:

  • 1 X USB-C to USB-C (right angle)


  • 1 X USB-C to Lightning (right angle)

The AT-USBC-JB can include a range of short, medium, or long cables provided by PoE Texas.  It is also compatible with most USB-C cables.

Note: Apple’s USB-C to lightning cable will function with this device to deliver power, however, that particular cable is NOT designed to deliver power and wired data simultaneously.  For that purpose, we’ve designed our USB-C to Lightning Cable.




Your new PoE converter is designed to be simple to install and set up.  It is small and light enough to leave “inline” with your network cable and designed to fit inside a US single gang wall box or 60 mm deep EU round wall box.

Once it is in place, simply follow these steps in order:

1 – Plug the RJ-45 end into an IEEE 802.3at PoE (POE+) or 48-56 volt passive Power Sourcing Equipment (PSE) with a data source

2 – Ensure the device you’re connecting to is on and logged in

3 – Plug the USB-C connector into the device using the port you prefer

The AT-USBC-JB is NOT designed to have a device plugged into both ports at the same time.  Please select one port for one purpose.

Option 1 – USB-C Fast Charging Only – Ideal for when you want to use wireless data or you have a MicroUSB device such as Lenovo M10, Amazon Fire, and more – Not recommended for devices such as iPads with a USB-C port or Surface G – see Option 2

In order to keep this device as compact as possible, the USB-C ports do share the Power Delivery (PD) communication pins.  If your device turns the power and data on/off rapidly after connecting it, unplug the USB-C cable at the AT-USBC-JB connector, rotate it 180 degrees and reconnect it.

Option 2 – USB-C Power Delivery + USB 2.0 Data – Ideal for iPads (lightning or USB-C), Surface Go, Samsung Tab, or Google Pixel Phones

The converter will automatically set up the network connection with your device and begin charging.  To confirm that, go to the General settings tab or look for the <…> symbol next to Ethernet.


Configuring Your Cisco Enterprise POE Switch for 2 Event PoE Classification

Yeah, I know that’s a mouthful.  Here’s the simple translation.  Cisco enterprise switches including the 9400 and 9300 models, which is a lot of them, come with a default setting that makes them less compatible PoE+ devices like the GAT-USBC-PD.   You’ll know the setting isn’t right because our device won’t power on correctly, and your device won’t charge.  How frustrating!

It’s a simple enough fix.  You simply need to configure the ports that will power the GAT-USBC-PD to have 2 event classification.  You can find the Cisco documentation on how to do that here: CONFIGURE MY SWITCH

Or here are the steps you take after you’ve logged into the terminal. 

Switch> enable
Switch# configure terminal
Switch(config)# interface gigabitethernet2/0/1

Switch(config-if)# power inline port 2-event
Switch(config-if)# end

You can still set up your iPad to not automatically lock on a timer.  When the screen locks if you would like the screen always on.

  • Go to the Settings icon on your iPad
  • Select Display & Brightness
  • Select Auto Lock
  • Set the limit to Never



The splitter will auto-configure the IP settings to default as soon as you connect it up including Dynamic IP addressing.

  1. Navigate to General Settings, then you’ll see a symbol for the LAN <…>
  2. Select this and you’ll see the option for PoE Texas LAN, select it

You’ll see your IPV4 IP address information.  If it shows “Automatic”, that means your getting a dynamically assigned IP address.

If you’d like to reconfigure the IP address, DNS, and HTTP Proxy settings, you can do that by selecting these options.  

The most used option will be fixing your IP address by selecting the “Automatic” button.

For the other networks settings, we’d recommend talking to a service provider or give us a call: 512-479-0317 or service@poetexas.com.

Best Practices for iOS Updates

Despite Apple’s excellent reputation for ensuring backward compatibility with their iPads and iPhones, practical experience with a recent iOS update has revealed that even they can miss things which can temporarily lead to disruption of service for your device.   If your device must be reliable 24/7, we recommend these following best practices:

  • Go to Settings -> General -> Software Updates -> Automatic Updates
  • Deselect “Install iPadOS Updates”
  • Before choosing to install the next update, please check into our iOS Compatibility Table to check whether we have finished testing the performance of an new iPadOS version
