Serial Communications
NetController’s four programmable communications ports can be configured as either an
RS-232 or an RS-485 interface to modems, printers, third-party devices, and the
Infinity
Infinet field bus network. Andover Controls has developed an extensive library of third-
party software interfaces, including tie-ins to chiller control panels, fire alarm systems,
emergency generator systems, bar code readers, elevator controls, and video switchers.

Programming
The
Continuum
NetController can be configured to meet the exact requirements of your
application using the powerful Andover Controls
Plain English
programming language.
Programs are entered into NetController using the
Continuum
Workstation. The program
is then stored in, and executed by, the NetController.
Software Capabilities
The dynamic memory of the
Continuum
NetController can be allocated for any
combination of programs, scheduling, alarming, reporting and data logging. Our object-
oriented
Plain English
language with intuitive keywords provides easy operation and
programming. In addition,
Plain English
‘s pre-defined and customized functions and
powerful math capabilities reduce programming time for repetitive applications.
Optional Auto-Baud Modem
The optional Andover Controls
Continuum
modem allows NetController to communicate
and exchange data over standard voice grade telephone lines with speeds up to 14.4K
baud. The modem has built-in data compression and error-correction protocols, auto-
dial/auto-answer capabilities, and is UPS-supported.
UPS Operation
The
Continuum
NetController incorporates software programmable battery backup that
reduces or eliminates the impact of power failure. On UPS, the NetController CPU can
turn off I/O power to extend battery life and support modem and network operation for up
to four hours. In addition, NetController can go into a low-power mode in which only the
DRAM and real-time clock are powered for up to 72 hours.
Modular Design for Snap-Together Connection
NetController features a sleek, lightweight casing designed for natural convection cooling.
Built-in connectors on either side of the NetController module allow power transmission
from the power supply module and communication signals to the
Continuum
I/O modules
to feed through easy snap-together connections. Built-in quick-release fasteners at the
back of the module are provided for DIN rail mounting
no tools required. These
fasteners also snap into a locked position for panel mounting. The NetController module
is designed for mounting in an optional NEMA 1-sytle
Continuum
enclosure.
