CONFIGURATION
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
3CDU 1.0.0 onwards
8CDU 1.0.0 onwards
Maximum number of CDUs
3

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.

Personalising the Site Map Schematic
The site map is normally the default schematic which is displayed when a user logs on to the
CDU-AC5 and presents the CDUs which are attached to the CDU-AC5.
A newly installed CDU-AC5 will not be attached to any CDUs –this is represented by the
following site map schematic.
Once you have attached a CDU to the CDU-AC5 (see section 5.1 and 5.2), a CDU icon will be
displayed on the site map. In the schematic shown below, a CDU with network address #1
has been attached.
Attaching a CDU with Network address #2, #3 etc will be represented by CDU icons
positioned to the left of CDU #1.

to 4096 bits. For inputs 5 to 9, this input range corresponds to 0 to 1024 bits.
Resistive Inputs
Displays the current state of each of resistive input. The value displayed is in multiples of
100ohms. E.g. 61 = 6k1ohms.
Analogue Outputs
Displays the current state of each of analogue output. Each output is specified as 0 to 10V –
corresponding to a displayed value of 0 to 255.
