Metretek InvisiConnect
InvisiConnect
®
Server is a software application that acts as a modem emulator and a
transparent “bridge” to the internet.
The CNI2 acts as an alarm
-
se
nsing unit as well as a transparent communications link between
a device attached to its serial port and the host system that is connected to InvisiConnect
®
Server. The CNI2 does not support pulse
-
counting in this mode.

Mercury MINI

MAX or Mercury Pulse Accumulator
When the CNI2 calls into the data collection system (
DC
-
2009
®
or MV90
®
) it will identify itself as
a
Mercury MINI
-
MAX or Mercury Pulse Accumulator.
In this mode the CNI2 serves as a data
logger for pulse
-
counting and alarm sensing applications and uses the legacy
Mercury
Instruments
communications protocol.
DC
-
2009
®
supports
both of these settings
. MV90
®
can support either
setting
depending upon
which options were purchased
for
MV90
®
.
Mercury Pulse Accumulator
is recommended
because there is less data to transfer resulting in shorter calls. If
Mercury MINI
-
MAX
is
selected the CNI2 will report values of 0 for any parameters relating to pre
ssure or temperature
measurements.
Metretek SMS Modem
This mode is primarily used by the InvisiConnect
®
Server software.
In a traditional wired
modem setup the central computer can usually contact the
remote device
directly by dialing its
phone
number. On the Internet there are servers and clients. A server is usually a computer
system that is always running and always “listening” for connection requests from clients.
When you use your personal computer to access a website your PC is the clie
nt and the
website is the server.
A client cannot be contacted
directly
via the Internet. In many cases the CNI2 acts as a client
only
.
However the CNI
2
can be paged”. The page then causes the CNI2 to call back
immediately to the central office.
O
ne method of paging is by Short Message Service, or SMS. SMS is often used to send short
text messages between two cellular phones. In some cases a message can be sent from a
computer using a traditional SMTP (email) server.
NOTE
At the present time the CNI2 does not fully support
Mercury MINI
-
MAX
or
Mercury Pulse
A
ccumulator
modes of operation.
