Frequently Asked Questions

Below are some of the common questions we receive about our software.
If you’re wanting to learn more about how to use SignCommand, we recommend starting with our video tutorials.

If you receive this error when sending or downloading a playlist, please duplicate your entire playlist using the “Copy” button on the main playlist screen.  Then send or download the copied playlist.  You may delete the original playlist after confirming that the copy works correctly.

A temperature slide will only show if the sign has recently received updated temperature information for your area. This is to prevent the sign from showing inaccurate information. The sign receives this data from an online weather service, which may be unreachable for the following reasons:

  • The sign is offline. Check that your sign is online within the Signs page of SignCommand. If not, follow the Offline Sign Help instructions to bring your sign back online.
  • The connection is being blocked by a proxy server, firewall or other network appliance. Part of the network may be blocking the communication. Check with your network administrator that all subdomains of (* are reachable from the network. In particular, if you use a Barracuda Web Security Gateway, ensure that is allowed with an SSL/TLS connection.
  • The weather service is offline. While very unlikely, the weather service may be down. This issue would be resolved in a matter of minutes or hours, so wait to see if the service resumes. If not, it is most likely one of the two issues above.

Once the sign can reach the weather service, normal operation will be resumed. There is no need to resend your playlist. If this does not resolve your issue, please contact support.

To protect your account, the adding or removing of users is performed by our Support Department after verifying your identity. Please use our contact support form to request this change.

If you have a scheduled call with a technical support representative, please follow these instructions in advance of the call so that we may more quickly assist you.

  • Be near the sign site and at a computer that has internet access.
  • Retrieve your sign’s diagnostic information and have it available to email to the technician.
  • If there is a visible issue with the sign such as a problem with an LED board, have digital photos available to email to the technician.
  • Know the location of your sign’s circuit breaker or other power disconnect switch.

Please see our full list of software, network and hardware requirements on our support page.

Using a text editing program such as WordPad, create a new plain-text file.

On the first line of the text file, you will be typing a date and time. Select the date and time that you plan to be out at the sign (such as five or ten minutes in the future). Enter the date and military time in the following format:

YYYYMMDD hh:mm:ss
(example: 20160926 14:30:00 for 2:30pm on 9/26/2016)

Optionally, on the second line of the text file you can place the timezone. Commonly used timezone values are:


A full list of valid timezone values can be found here.

Save the text file with a name of time.txt in the root folder of an empty USB drive.

At the time you specified above, plug the USB drive into your sign’s external USB port. This will update your sign’s clock, and your new date and time will show automatically. However, if you entered a timezone you will need to turn your sign off and back on for the new settings to take effect.

By default, signs are set to retrieve the official date and time from an internet time source on a regular basis. This should prevent your sign from drifting out of sync with official time, or when the time changes as with Daylight Saving Time. However, this requires that the correct timezone information is set on your sign. If you are seeing an incorrect current date or time, follow the instructions to update the time on your sign with a USB drive and specify your correct timezone.

Please note that signs that are not connected to the internet will not be able to automatically retrieve official date and time information. For these signs, you must update the time via USB drive for time changes.

We use the industry-leading weather service to retrieve the current temperature information for your area, the same service that is used by The Weather Channel.  Please note that current temperature information may take up to 10 minutes to be shown on your sign.

If the temperature on your sign is significantly different from the weather service, this may mean that we have the wrong zipcode listed for your sign.  Please contact support to correct the issue.

Your sign will automatically update its software when necessary.
Updating your sign’s software manually is not recommended unless directed by a support technician or from an error code solution.

How to determine if your sign has a software update available.

  1. Follow the instructions to retrieve your sign’s diagnostic information.
  2. Within the text file, look for the dates listed after the lines starting with Player Version and Player Patch.
  3. Compare those dates with the dates listed on the Files & Downloads page.
  4. If there are newer versions available for either file, you may proceed to manually update your sign.

How to update your sign’s software manually.

  1. Download an upgrade from the Files & Downloads page. The file’s name will end with .upgrade.
  2. Place the downloaded .upgrade file onto an empty USB drive.
  3. Plug the USB drive into the USB port on your sign (if equipped).
  4. When the sign’s display goes completely black, the sign is rebooting.  You may then remove the USB drive.

Your sign is now updated.  Be sure to remove the .upgrade file from the USB drive before using it again.

If applying the Player upgrade, you must apply the Patch upgrade afterwards.

See our video tutorial.

  1. With your sign turned on, plug an empty USB drive into the external USB port on the sign (if equipped).
  2. Leave the drive in the sign until you see a message on the sign indicating that it is ready to be removed. This will download all of your sign’s diagnostic information to the drive into a text file named signinfo.txt.
  3. Plug the USB drive into your computer and open the signinfo.txt file on the drive by double-clicking on it.

If your sign hasn’t connected to the internet in a while, an “Offline” indicator will appear next to it. Don’t worry! This is usually a result of a temporary connection problem between your sign and the internet.  During this time, you won’t be able to control or see the status of your sign remotely.  However, SignCommand signs are designed to continue functioning without being able to connect to the internet.

Your sign is capable of showing the existing playlist, including all scheduled slides, without an internet connection. As long as there is power at the sign, most likely your current message is continuing to play.

If your sign does not resume normal operation, see our Offline Sign Help page for a full troubleshooting guide.

If you are an existing user of SignCommand, you may receive support by completing the Contact Support form or Self-Schedule for Customer Support.
