No Pennies? No Problem!

Tue, 06 Jan 2026 21:49:01 GMT

With the United States no longer minting new pennies, many retailers are having trouble obtaining sufficient pennies to provide change and are rounding cash transactions to the nearest available denomination (typically $0.05). To support this change, Atrex includes a Cash Rounding feature that ensures cash-only transactions are handled accurately and consistently.

How to Enable Cash Rounding

From the main window, select "Options - Company Information / Customization - Company Information and Settings".
Select the Defaults tab.
Locate the Round Cash option.
Set the drop-down value to Rounded and then choose the rounding increment you want to apply (for example, $0.05).
Click the OK button to save your changes.

Once enabled, the setting takes effect immediately for new cash transactions.

When Cash Rounding Applies

Cash rounding is only applied when all of the following are true:

Cash rounding is enabled in Company Settings
The transaction is paid entirely in cash
The transaction total includes a value that requires rounding based on your selected increment

Applies to Atrex 14+

CardKnox Desk/5000 Setup (Canada)

Thu, 13 Oct 2022 19:57:06 GMT

The Ingenio Desk/5000 is a semi-integrated device for use with CardKnox for Canadian card processing from within Atrex. This KB article will go over the specific device settings required to configure the physical device for use with Atrex.

IP Address: In order to communicate with the device, you must know the IP address of the device. When first powered on and connected to the network, the device will automatically obtain a dynamic IP address and keep the assigned address for as long as it is powered on and maintains the connection to the router. If the power to the device interrupted or the device is disconnected from the network, the IP address may change resulting in the inability to connect to the device. As such, it is best to assign the device a static IP address that will not change.

Press the # key on the keypad.
Select the "Setup Menu" menu selection.
Select the "Communications" menu selection.
Select the "Ethernet" menu selection.
Select the "Current Setup" menu selection.
Make note of the IP Address, Gateway IP, Subnet Mask, and the Pri DNS entries. If the IP address shows 0.0.0.0, it has not yet been assigned an IP address. In this scenario, cancel out of the display, wait 30 seconds and display the settings again.
Press the red "x" button to return to the Ethernet menu.
Select the "Ethernet Setup" menu selection.
Select "Static IP" and press Enter.
Enter an IP address for the device that uses the same first 3 segments of the dynamic IP address followed by a number that is outside of the dynamically assigned range. Numbers above 200 tend to be available. If the IP address you noted in step 6 was 192.168.1.100, enter 192.168.1.201 for the first device, 192.168.1.202 for the second device, etc.
The device will usually automatically set the GatewayIP, IPSubMask, and PriDNSIP fields for you. If they are not set, use the Gateway IP, Subnet Mask, and the Pri DNS entries values that you noted in step 6 for these fields.
Press the green Enter button on the keypad to save the settings.
Select the "Current Setup" menu selection and verify that the IP address that you assigned the device is now the current IP Address. If it is NOT, the IP address you assigned the device is not available and you will need to designate a different IP address.

If your network configuration changes significantly preventing connectivity to the device, you may need to reset the device to a dynamic IP address, wait about 60 seconds, and then reconfigure the device for a static IP address.

Important: Please note that the Lane 5000 device is updated periodically from the back end processor, which will reset the device back to a Dynamic IP address. Once you have configured the device for a static IP address, you will need to contact CardKnox and inform them of the assigned IP address information along with the injected serial number for each device you have so that they can have the back end configuration file updated to make sure that the device is always accessible. You can file the Injected serial number for the device using the following steps:

Press the [#] key
Press [7] for Terminal Info
Press [1] Terminal Info and scroll down to injected serial number.

Key Load: The device initially ships without a device specific EMV encryption key, which needs to be set prior to processing transactions.

Press the # key on the keypad.
Select the "Host Management" menu selection.
Select the "EMV Public Key Load" menu selection.
Select the "EMV Public Key Load" menu selection.

The device will immediately begin downloading they key.

Enable Card Present Split Payments: The Desk/5000 has an option to ensure that the same transaction number cannot be used multiple times to prevent duplicate charges. You must disable this functionality to allow splitting a transaction across multiple cards.

Press the # key on the keypad.
Select the "Setup Menu" menu selection.
Select the "Trans Options" menu selection.
Select the "Prompts" menu selection.
Set the "DupTran" option to "Off".
Set the "DbDupTran" option to "Off"
Set the "DupInvNo" option to "Off"
Set the "Invoice" prompt to option "2. Invoice"

Enable Semi-Integrated mode: The device must be configured for semi-integrated processing. Please note that this option may not be necessary for your device. If you do not see the menu selection for step 3, your device is defaulted to Semi-Integrated.

Press the # key on the keypad.
Select the "Misc. Options" menu selection.
Select the "Semi-Integrated" menu selection.
Set "Enable SemiInteg" to "On".
Set the "Communication Type" to "Ethernet" when prompted for the type.
Set the Terminal Port to 9999 when prompted.

Terminal Semi-Integrated Mode / Stand-Alone Mode: The device can operate in either Semi-Integrated mode or Stand-Alone mode.

When in Semi-Integrated mode, you will see the words "Semi-Integrated" at the top of the display along with an icon that represents the physical device the upper right corner. The Semi-Integrated mode must be enabled for Atrex to communicate and process sales through the device

When in Stand-Alone mode, you will see an icon that represents a cash register in the upper right corner. In this mode, you can process sales, voids, and returns outside of Atrex.

You can toggle between Semi-Integrated and Stand-Alone mode by pressing on either of the icons and following the prompts.

Device Receipt Printing:

Press the # key on the keypad.
Select the "Misc. Options" menu selection.
Select the "Semi-Integrated" menu selection.
Select the "Receipt Options" menu selection.
Select "ECR" to disable the printing from the device, or "Both" to print from the device and from Atrex.

POS-X ION Cash Drawer Driver - Windows 11

Fri, 22 Apr 2022 17:43:40 GMT

Recent security updates to Windows 11 prevent the ION cash drawer driver from directly accessing the chipset information for the virtual serial adapter. This is indicated by the description for the virtual com port in Windows Device Manager to show the following message for the device: "PL2303TA DO NOT SUPPORT WINDOWS 11 OR LATER, PLEASE CONTACT YOUR SUPPLIER."

Fortunately, the installed driver also includes an older version of the driver that CAN be used with Windows 11. Start Windows device manager by clicking on the Windows start menu, and typing in "Device Manager". Click on the Device manager app when it is displayed, navigate to the Ports entry and expand it. Follow the instructions in the images below to enable the driver in Windows 11:

Windows 11 Compatibility

Wed, 10 Nov 2021 16:37:16 GMT

Please note that as Microsoft makes updates and security changes to Windows, these compatibility statements may change depending on the effects of the Windows updates.

Atrex 20, 21, 22, 23

Atrex version 20 through 23 are fully compatible with Windows 11.

Atrex 16, 17, 18, 19

Atrex 16, 17, 18, and 19 have NOT been tested on Windows 11, and cursory testing of Atrex 19 indicates general functional compatibility with Windows 11. However, there is a known issue with these versions of Atrex randomly closing when run under Windows 11 and it is strongly suggested that you upgrade to the current Atrex version.

Please note that any incompatibilities between these versions of Atrex and Windows 11, will be corrected in the current version of Atrex.

Atrex 15 and Older

Older versions of Atrex, 15 and earlier, are incompatible with Windows 11 and are NOT supported on that platform even when run in compatibility mode.

Exceed the number of licensed users after power outage

Mon, 26 Jul 2021 21:05:20 GMT

A power outage, or improper shutdown of a computer, can result in damage to files used to facilitate record locking within Atrex. If this occurs, it can result in the message "Starting this copy of Atrex will exceed the number of licensed users".

You can attempt to resolve this issue using the following steps:

Close Atrex on all workstations.
Restart the server computer. If you are running a client/server configuration and cannot restart the server for any reason, restart the Atrex database server engine via the Atrex Database Server Administrator.
Before opening Atrex on any system, locate the data folder in Windows File Explorer, and delete ua_data.* from that folder.
Again in Windows File Explorer, locate In the central folder, and delete ua_atrex.* .

Unable to verify WooCommerce API Settings

Wed, 27 May 2020 04:53:33 GMT

The most common reason that you are unable to verify the WooCommerce API settings is that your WordPress settings are still using the default Permalink options. From your WordPress admin page, select the "Settings" option and then set your PermaLink option to one of the suggested options. Even if you don't change anything on this page, select an entry and click the "Save Changes" button to force WordPress to use a "Pretty" permalink option.
