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-sensing 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.
®
Contact a Honeywell Product Support Specialist for additional details about InvisiConnect .

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 pressure or temperature
measurements.
NOTE
At the present time the CNI2 does not fully support "Mercury MINI-MAX" or "Mercury Pulse
Accumulator" modes of operation.
Contact a Honeywell Product Support Specialist for additional details.

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 client 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 CNI2 can be "paged". The page then causes the CNI2 to call back
immediately to the central office.
One 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.
