Z8F2480 Power Monitor with an eZ80F91 Webserver
Reference Design
The measurement values are displayed when the web page is reloaded, when the Refresh
button on the page is clicked, or automatically every n seconds as determined by the set-
ting of the Automatic Refresh Period on the web page.
Note: When input exceeds recommended operating conditions, the web page shown in Figure 5
will display a warning message.
Setup, Configuration and Use
This section describes how to set up, configure, and operate this reference design.
Setup
This Power Monitor with an eZ80F91 Webserver reference design is delivered with soft-
ware installed and ready to use. However, be aware that the unit may require calibration.
To learn more about calibrating the unit, see the Calibration section on page 15.
To view the Power Monitor web page, observe the following procedure.
1. Disconnect AC power from the Power Board and attach the eZ80F91 Webserver Mod-
ule to the bottom of the Power Board. Be sure to properly align Pin 1 of J2 on the
Webserver Module with Pin 1 of the Power Board to prevent bending any pins. Note
that pin 60 of J2 on the Module (located at the bottom right of J2) is missing, and that
Pin 1 of J2 is located at the top left corner of J2. Do not attempt to connect J1 on the
eZ80F91 Webserver Module to the Power Board; refer to Figure 2 on page 2.
2. Connect an Ethernet cable between the RJ45 connector (P1) on the eZ80F91 Web-
server Module and the switch or hub that will be used by the PC to browse the Power
Monitor web page. This connection will ensure that the PC and the eZ80F91 Web-
server will be assigned an IP address within the same subnet.
Note: The eZ80F91 Webserver has been preconfigured to use DHCP to obtain IP parameters;
this setting is appropriate for most networks. If your network uses DHCP, proceed to Step
3. However, if the LAN segment to which the eZ80F91 Webserver module is connected
uses static IP addresses, it will be necessary to recompile the eZ80F91 project and repro-
gram the Module. In this instance, it will be necessary to download and install Zilog
Developer Studio (ZDS II) for eZ80Acclaim! version 5.2.0 (or later) with RZP and TCP/IP
Object Code; this software can be downloaded free from the Zilog Store. After installing
ZDS II, proceed to the Recompiling the eZ80F91 Webserver Software section on page 13.
3. If you have not yet installed the software for this reference design, see the hardcopy
insert included in your kit, or navigate the default installation filepath, which is:
C:\Program Files (x86)\Zilog\ZRD0027PLM0ZRD_<version>\Docs\
