A system for remotely accessing diagnostic information from an access control module includes a host device. The host device is configured to interface with the access control module over a direct connection to retrieve diagnostic information from the access control module in response to a host query from the host device, and to interface with a network server over an Internet protocol (IP) network to provide the diagnostic information relating to the access control module to the network server in response to a server query to an IP network address of the host device. The access control module is non-addressable in the IP network.
