Watchdog function


The CX-6p-PoE has a watchdog feature which allows it to monitor the function of up to
four network connected devices. The CX-6p-PoE can monitor a network device by
periodically sending ping requests to the device over the network. After a number of
pings without responses from the target device, the CX-6p-PoE takes an action which
can be configured by the user. This action can consist of either setting an aux contact
output on the CX-6p-PoE for a set period of time, sending a TCP message over the
network to a user-defined destination, sending an alarm email to a user-supplied
address, or cycling power on one of the four POE powered Ethernet ports on the the CX-
6p-PoE.

This feature permits the CX-6p-PoE to monitor an external piece of network-connected
equipment, and on detection of a failure trigger an alarm, notify a technician, power-
cycle an external device through a relay, or directly cycle power on a POE powered
device connected to one of the four POE powered ports on the CX-6p-PoE.

Pilot interface

The CX-6p-PoE is intended to communicate over the network with up to four Pilot server
devices. The user will provide an address and port number for each of the Pilot servers
he wishes the CX-6p-PoE to communicate with. The CX-6p-PoE will automatically
attempt to connect to Pilot servers when a valid IP address and port number have been
provided.

Once connected to a Pilot server, the CX-6p-PoE will send updates of the status of all
alarm inputs and aux outputs, along with the latest readings from all connected
environmental probes, to each Pilot server every 5 seconds. It will also send immediate
updates every time an alarm input or aux output changes state, or when a probe reading
exceeds warning or alarm thresholds. These messages can trigger events in the Pilot
VMS software.

Environmental Probes


The CX-6p-PoE is designed to connect to up to two AFI environmental probe devices.
These devices are used to monitor environmental conditions such as temperature,
humidity, and airflow, or to monitor the power being used by customer equipment.

When a probe is connected to the CX-6p-PoE, the CX-6p-PoE will automatically detect
the probe type and read the probe’s serial number, user-definable name, and all alarm
and warning bounds and programmed actions from the probe’s memory.

Once a probe has been connected and all configuration data read from it, the CX-6p-
PoE will every ten seconds read the latest set of environmental readings from the probe.
The latest readings will be displayed on the web page, and forwarded to any connected
Pilot servers. If any of the readings are outside the set warning or alarm levels for that
probe, the CX-6p-PoE can take several programmed actions, setting an aux contact
output on the CX-6p-PoE for a set period of time, or sending an alarm email to a user-
