DESCRIPTION
The ENG-485 and PT-NTL-10 are communication modules for
EnGenius™ Intelligent Power Monitor. They read data from the
EnGenius™ main processor, format the data, and transmit it to a
network. They allow all of the power system parameters measured
by the EnGenius™ to be monitored over a single pair of wires.
The ENG-485 contains BACNET, Modbus and N2 communication
protocols. The chosen communication protocol is selected either
through the front panel display/keypad or the desktop software.
The ENG-485 features 2 contact-closure inputs for monitoing
external equipment. Each input can be configured to read
contact state (On/Off) or as a Pulse Counter to count pulses
from flow meters or other power meters. In the Pulse Counter
mode, a Clear command is available to reset the pulse count
when desired.
The PT-NTL-10 is a a dedicated Lonworks communication module.
This module does not have the 2 contact-closure inputs.
FEATURES
