6. To reprogram the Power Board, it is necessary to use a Zilog debug tool such as the
USB SmartCable. Before proceeding to download new code to the Power Board, dis-
connect AC power from the Power Board. Next, connect a 6 V (or higher) DC power
supply between pins J1-1 (+) and J1-2 (–). This step safely provides power to the
Z8F2480 MCU on the Power Monitor Board for the purpose of reprogramming the
firmware without a direct connection to AC main power.
7. Connect the 6-pin ribbon cable between the USB SmartCable and the Power Board’s
J4 connector.
8. In the ZDSII IDE, click the Download icon ( ) to reprogram the Power Board.
9. When the download is complete, disconnect the power on J1-1 and J1-2. Next, discon-
nect the 6-pin ribbon cable from the Power Board’s J4 connector. Then, with AC
power OFF, reconnect AC power to the Power Board’s J1 terminal.
Recompiling the eZ80F91 Webserver Software
The Webserver Module is delivered with software installed and ready to use. However,
this software may require calibrating to accurately display voltage and current values.
Source code for the Webserver Module is available in the RD0027-SC01.zip file that is
included with this reference design. To modify the software and/or learn more about how
the software operates, users must obtain a copy of the ZDS II for eZ80Acclaim! Integrated
Development Environment before being able to modify the software and reprogram the
Module.
Observe the following procedure to download and install the ZDS II software.
1. Download the latest version ZDSII – eZ80Acclaim! from the Downloadable Software
category of the Zilog Store.
2. Run the software installation file and follow the on-screen instructions to install
