INTRODUCTION
ZiRC is a low cost Remote Control reference design based on the SD3502 for dual-mode, Z-Wave and
InfraRed (IR), control of Sigma Designs Internet Television (IPTV) Set Top Boxes (STB). User feedback is
through a tricolor LED (red, green, amber) located next to the power button. As a Z-Wave device it can
interwork with any other Z-Wave certified device from any vendor.
ZiRC can control the STB both in IR mode and in Z-Wave AV mode. The IR mode is using NEC format
with a target address of 0xCB04. On first power up, the ZiRC is in Z-Wave AV (Audio Video) mode. While
the IR mode can be used immediately, the ZiRC mode requires the remote to be included into the STB’s
Home Area Network first.
From time to time, this manual may refer to STB operations that are not covered in this document, but
rather in the STB’s manual.
