Secondary Hardware Components of the HQ-ST System
The HQ Remote Console and HQ Remote Poller provide the capability to locate a parallel "HQ site" which can be
readily re-located. The HQ Remote Console and the HQ Remote Poller can be deployed as standalone devices, at the
same or at separate sites. Enabling and disabling of the remote devices is controlled from the main HQ Plus through
the HQ Basic software control to allow or disallow remote console and remote poller functions accesses.
HQ Remote Console
Figure 7: HQ Remote Console: DB-9F serial connector
The HQ Remote Console provides an output of the "current connection status" of the system, via the serial port on the
HQ Remote Console device.
The data output is a "duplicate" of the output from the main HQ Plus, which may be located elsewhere on the WAN,
LAN, or Internet.
The PC that is connected to the serial port of the HQ Remote Console runs the HQ Basic utility. The same control
capabilities exist at the HQ Remote Console site at the main HQ Plus.
The HQ Remote Console can be located anywhere where there is an Internet communication capability available. Only
one HQ Remote Console may be associated with any one HQ Plus, and the site LAN requirements are the same as for
an ST Plus installation.
The HQ Remote Console communicates with the main HQ Plus in a way similar to that used by a standard ST Plus.
HQ Remote Poller
Figure 8: HQ Remote Poller: DB-25F serial connector
The HQ Remote Poller hardware provides the capability to use polling software applications to poll and communicate
with the ST Plus devices that are "connected" to the main HQ Plus.
Only one HQ Remote Poller may be associated with any one HQ Plus.
The site LAN requirements are the same as for an ST Plus installation.
