Help, I can't sign up, my label does not have a checksum
Up to Table of Contents
The online sign-up process can only be done by users who have a GS-911 interface, and who have both the Serial number AND checksum, whether the checksum in printed below the Serial number on the barcoded label, or whether you've received it from us directly.

We started shipping these in September 2008 - if your interface has such a label, please follow the online sign-up process!
- There might be a couple of interfaces that are shipped by our resellers that do NOT yet have the Checksum printed under the Serial number on the barcode label (as they are moving the previous month's stock) - your reseller will email you your Login details.
Customers without a checksum printed on the barcoded label:
If you are a new customer, an account will be created for you automatically. The account details are emailed to you along with your shipping confirmation (tracking number etc.), by YOUR Reseller. You will automatically be a Validated Customer once you receive your GS-911 shipping confirmation! These emails are sent ONLY once the package has been shipped, which generally is within 2 working days after receiving the order.
Not yet received your Login details:
If you have received your GS-911 package and have NOT yet received the email with your login details, then please check the following (in this order):
- You have one of the new interfaces that allows you to register it using the online sign-up process - successful completion of the online sign-up process will be your Login and password details.
- your SPAM filter - it might have filtered out the email you are waiting on (either from the online sign-up process or from you Reseller).
- If you're waiting on an email from your Reseller, containing your Login details, then contact YOUR reseller, to get your Login details resent to you.
