CDU-AC5
2.1 Features and Capabilities
Graphic Hosting. Hosting of schematics which can real-time data fields retrieved from
the locally connected CDUs via the LonWorks network. Adjustment of set points and
other configuration property values is provided with relevant security schemes.
Schematics can be viewed from Windows Internet Explorer, and achieved with the
support of a signed ActiveX control.
Alarming & Re-transmission. Generation and storage of alarms from local CDUs. Re-
transmission via E-mail or SMS (requires GSM Modem).
Data Logging. High capacity logging to miniSD card. Multiple sources and log intervals
are supported.
SNMP. SNMP agent support, providing a monitoring solution to existing network
management systems.
MODBUS. MODBUS slave support via a RS-485 serial communication link, providing a
monitoring solution to any Building Management System (BMS) that supports MODBUS
RTU protocol.

use 24Vac if the CDU-AC5 is mounted in a CDU and mains if it is rack-mounted.
Mains Power Supply Option
24Vac Power Supply Option
NOTE: The CDU-AC5’s 24Vac power supply is polarity sensitive –it is
extremely important to get the 24v & 0v in the correct orientation to avoid
damage to the CDU-AC5

4.2 Local LonWorks Network
The CDU-AC5 communicates with connected CDUs over a LonWorks twisted pair network. A
typical network is shown in below,
4.3 Accessing the CDU-AC5
The CDU-AC5 can be accessed from a client PC running Microsoft Internet Explorer 5 or
above. The following security options must be enabled within Internet Explorer,
Scripting
Active X Controls
The CDU-AC5 communicates using a number of standard and non-standard TCP ports. If
access is to be gained through a firewall, the following ports are should be open.
20-21
80
44000 –44002
50000 –50010
The default IP configuration of the web server is
IP Address 192.168.11.22
Subnet Mask 255.255.255.0
Default gateway 0.0.0.0
4.4 Installing the Active-X control
When accessing a CDU-AC5 for the first time, an Active-X control will be downloaded and
installed on the client PC. The download is an automated process - the user only needs to
confirm several security prompts.

CDU-AC5
5.1 General
A CDU-AC5 can monitor and control a number of CDUs. The number of CDUs which can be
connected to the CDU-AC5 is dependent on the CDU-AC5 firmware. As of writing the
following firmware images are available,
CDU-AC5 Firmware Version
Maximum number of CDUs
3CDU 1.0.0 onwards
3
8CDU 1.0.0 onwards

A CDU must be connected to the CDU-AC5 gateway using the procedure documented in this
section.
5.2 Configuring the CDU’s Network Address
Before a CDU can be attached to the CDU-AC5 gateway it must be given a unique network
address. Typically, network addresses are allocated to CDUs in ascending order, starting
from 1. Configuration of the CDU network address is carried out via the CDU’s graphical
display.
