e-mail Sales and Support questions to: 

Please note that the email address of individuals at PMDX may have changed if you obtained them before the year 2009. Use the link above to assure correct delivery.

We would appreciate it if you would put PMDX and a few keywords related to your inquiry somewhere in the subject line to make your E-mail easier to find in the future, and to stand out from the increasing amount of SPAM that we receive.

Please note: E-mail is the recommended method of contact as it does not rely on catching a particular person in the office and automatically provides a reliable record of your query and a method of responding to the correct party. It also allows you to include information such as links to the manuals for other products that you are connecting to our boards. We realize that some questions are too complicated for email or lead to long discussions, so we do offer support on the phone. Technically knowledgeable personnel are not always available to answer questions when you call, so please leave a message if you need to talk to technical support and no one is currently available. Recommended calling times are 9AM to 6PM for the Eastern USA time zone.

                           or photos to it as they will not be received.

Most of our competitors no longer offer telephone support. While this is regrettable, please be considerate of our time and do not expect us to support another vendor's product unless it is being used together with a PMDX product. We do support Mach products when purchased from us even when not used with PMDX products, but this support relates only to the Mach product itself, not to plug-in installation and custom configuration of another vendor's product.
