    Basic Polling

    LAVA HQ-ST Plus Links will IP-enable your serial-port equipped ECRs and POS stations, making remote polling and uploading pricing information a snap. Operation is transparent to both the store hardware and to the polling software.


    This is the most secure link on the market. Because no store-side router port mapping is performed, there is no “hole” created in the store’s firewall. At the head office, the HQ unit needs just one port mapping, regardless of the number of store units connecting to it. All needs for network skill are centralized: an enormous benefit and cost savings when deploying devices to geographically wide-spread stores.

    The LAVA HQ-ST Plus Link also offers enhanced security over conventional serial device servers by having only authenticated connections between the store and the head office.

    Management and Monitoring

    The LAVA HQ-ST Plus Link provides another critical benefit to chain store and restaurant operators: monitoring and management of remote ECRs and POS stations.

    The LAVA HQ-ST Link also provides status monitoring that lets you instantly know when a store’s ST Plus unit is online or offline, and back-end management software allows head office users to maintain a database of store information that can show when an exception is noted on the polling network. If a store is off line during store hours, if a network connection comes online when it shouldn’t, if an unauthorized store unit attempts to access the HQ Plus unit, and so on, you’ll know!

    Deployments of Virtually Any Size

    The LAVA HQ-ST Plus Link scales well to the needs of virtually any size business.

    Unparalleled Ease of Installation

    This is where the LAVA HQ-ST Plus Link really shines. It deploys with no need to configure the port mapping parameters of the store-side router.

    This is not the case with any IP-based ECR or serial device server on the market.

    The savings that result from this feature are huge: HQ-ST Plus Links can be deployed with little networking expertise, and installers have no need to know anything about the router or ISP used by the site! One company estimates installation time will be reduced by 2½ hours per store.


    HQ Remote Console

    This unit allows a user — or a dealer supporting a user — to create a head office away from the head office. The HQ Remote Console unit makes it possible to redirect the console data being received at the head office to another IP address, for display in an instance of the LAVA HQ Basic software interface running at that location. All management capabilities of the head office are available through the remote console, but the “true” head office remains in ultimate executive control.

    HQ Remote Poller

    This unit allows a user – or again, a dealer supporting a user — to remotely poll stores from any IP location outside the head office, through the actual HQ Plus unit operating at the head office. The HQ Remote Poller provides the ultimate assurance that the full HQ Plus Link is operating, and is ideal for verifying the success of a store installation when at the store itself.
