N2 Dialer Module—N2 Dialer Module (NDM) 9
Engineering
The NDM communicates using a standard telephone line and the components described
here.
•
Hayes Compatible Modem--a modem that uses the industry standard Hayes protocol
to set up, dial out, and hang up. The Hayes compatible modem is defined as Data
Communication Equipment (DCE). The NDM is defined as Data Terminal
Equipment (DTE) and supports TXD, RXD, RTS, CTS, DSR, SG (Signal Ground),
DCD, RI, and DTR RS-232 signals.
•
Universal Packaging Module--also referred to as the UPM. Use this enclosure to
mount the NDM as a standalone device or with other types of equipment to provide
a compact, secure environment. The EN-EWC12-0 easily accommodates the N2
Dialer Module, Hayes modem, and two plug-in adapter power supplies in a
standalone configuration. You may also use a larger UPM to contain other optional
equipment you may need.
You can use the N2 Dialer Module with either the Metasys® Network or Metasys
Companion

as the facility management system. Remote devices supported by the NDM
include the following:
Variable Air Volume Controller (VAV) DX-9100
Unitary Controller (UNT) TC-9100 Series
Air Handling Unit Controller (AHU) LCP
Phoenix Interface Device (PHX) XT-9100
Metasys Integrator
®
(MIG)
Early versions of the DX-9100 and TC-9100 series and all versions of the LCP cannot
generate dial-in alarms. Later versions of the DX-9100 and
TC-9100 series do support the remote NDM dialing in to report alarms to the facility
management system or passive device (e.g., printer). For specific information on using
the DX-9100 and TC-9100 series with NDM applications, see the controller technical
bulletins.
See Appendix A: Supported Devices and Firmware Revisions in this document for a list
of supported devices and their corresponding firmware revisions required for NDM
operation.
