This guide assumes that Ubuntu 22.04 or 24.04 is installed on the Host PC or a secondary machine interacting with USB-enabled Series 300 devices.
1. Only required for online installation.
To install the necessary drivers, follow the steps below. When you reach the “CUWB Applications Selection” screen during the setup process, ensure that CUWB USB Driver is selected for installation.
The CUWB USB Driver can be installed on Host PCs that do not have PPA access by using a standalone DEB package. Users should first refer to the Current Downloads Available section under Software Packages to obtain the correct package, then transfer the file to the Host PC using a USB drive or an alternative local transfer method. Once the file is on the target machine, navigate to the directory containing the package and execute the installation by entering the following into a terminal window:
sudo apt install ./cuwb-usb-interface_<version>_amd64.deb
The PT301 communicates directly with the local PC via USB, whereas the CUWB Manager Package is designed to interface with Ethernet-based systems rather than USB protocols. The CUWB USB Driver acts as a bridge, allowing UWB-enabled hardware like the PT301 to operate on the CUWBNET as if it were a standard Ethernet-based UWB device. To facilitate this connection, an individual instance of the CUWB USB Driver must be active for every PT301 device connected to the computer. This can be accomplished either by manually launching a separate client for each device or by utilizing the automated management features provided by the CUWB USB Driver service.
Plug in the PT301(s) that are going to be used as wired devices on the CUWBNet.
For PT301s, determine which USB interfaces(s) belong to the devices(s):
> ls /dev/ttyUSB*
/dev/ttyUSB0 /dev/ttyUSB1
Here in our example we have two PT301s connected to the local PC.
Determine which network interface you would like the PT301 to attach to:
> ifconfig
enps4s0 Link encap:Ethernet HWaddr 1c:6f:65:d3:38:b1
inet addr: 10.132.39.0 Bcast: 10.132.255.255 Mask: 255.255.0.0

Or if using the PT301 on the same PC that is running CUWB Manager Package, lo is allowed:
> ifconfig
lo Link encap: Local Loopback

RX bytes: 1187951355 (1.1 GB) TX bytes: 1187951355 (1.1 GB)
Run the CUWB USB Driver Client:
> cuwb-usb-interface-client /dev/ttyUSB0 lo
Alternatively, the CUWB USB Driver Daemon will dynamically attach ttyACM and ttyUSB devices to the selected interface:
> sudo cuwb-usb-interface-daemon lo
The driver can be stopped by using ctrl+c.

Ciholas is committed to protecting your personal information and your right to privacy. If you have any questions or concerns about our policy or our practices with regards to your personal information, please notify Ciholas at info@ciholas.com.
The following is to inform you of our policies for collecting, using, and disclosing your Personal Identifiable Information (PII) made available to Ciholas when you browse our sites, create accounts on our sites, purchase and use our services and products, and/or contact us through our support email. By using any of our services and products, you agree to the collection and use of your PII in accordance with this and other policies contained in this Agreement.
In the CUWB.IO Shop, we collect personal information that you voluntarily provide to Ciholas when creating an account, posting messages, or otherwise contacting us. The PII that we collect depends on the context of your interactions with Ciholas and the choices you make regarding the information you provide. The PII you share is up to you and is not required for browsing any of our sites. However, if you want to create an account, purchase an item in our shop, and/or call/email our support staff, you may be asked for PII. The PII collected is encrypted using secure socket layer technology (SSL).
The PII we collect could include the following:
Name and Contact Data – First and last name, email address, postal address, phone number, and other similar contact data.
Credentials – Passwords and similar security information used for authentication and account access.
Payment Data – All payment data collected through the website is by a third-party payment processor (TPPP). Ciholas DOES NOT have access to any of the payment information that you provide to the TPPP. None of the TPPPs use any of your data for anything other than processing your payment and have their own privacy policies, which are as strict as or stricter than, those contained in this privacy policy. Ciholas and all Ciholas TPPPs use SSL/TLS encryption for securing data. All Ciholas TPPPs are PCI DSS compliant for payment processing standards.
We use your PII for the purposes listed above and to keep our site safe and secure (for example fraud monitoring and prevention) and to enforce our terms, conditions, and policies for our legitimate business purposes.
We may disclose your information where we are legally required to do so to comply with applicable law, judicial proceedings, court order, or legal process, such as in response to a court order or a subpoena.
We will not share, sell, rent, or trade any of your PII with any third parties.
We keep your information for only as long as necessary to fulfill the purposes outlined in this privacy policy unless otherwise required by law.
We have implemented appropriate technical and organizational security measures designed to protect the security of any personal information we process. However, given that the internet is not 100% secure, transmission of personal information to and from our sites is at your own risk. Only access our services, products, and sites within a secure environment.
Based on the laws of some countries and states, you may have the right to request access to the PII we collect from you, change that information, or delete it in some circumstances. For more information on how to do that, please contact Ciholas at info@ciholas.com.
If you are visiting our sites from outside of the United States, please be aware that you are sending information (including PII) to the United States where our servers are located. That information may then be transferred within the United States or back out of the United States to other countries outside of your country of residence, depending on the type of information and how it is stored by us. These countries, including the United States, may not have data protection law as comprehensive or protective as those in your country of residence; however, our collection, storage, and use of your PII will at all times continue to be governed by this Privacy Policy.
We automatically collect certain information through web analytics when you visit, use, or navigate any of our sites. This information does not reveal your specific identity, but may include device and usage information, such as your computer’s Internet Protocol (IP) address, browser type, browser version, operating system, referring URLs, country, location, the pages of our sites that you visit, the time and date of your visit, the time spent on those pages, and other similar statistics. This information is primarily needed to maintain the security and operation of our sites and for our internal analytics and reporting purposes.
We collect this information using cookies. Cookies are small pieces of text stored on a user’s computer. They can be accessed by the web server or the client computer, allowing the server to deliver information tailored to the user. Most web browsers are set to accept cookies by default. We use cookies to keep track of items stored in your shopping basket, to conduct research and diagnostics to improve our content, services, and products, to prevent fraudulent activity, and to improve security.
If you prefer, you may choose to set your browser to remove and reject cookies. This could affect the availability of certain features, services, or products on our sites. Most browsers allow you to turn off cookie collection in their Tools/Settings button under a Privacy tab.
