USAGE
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.
2.1
Z-Wave Network Overview
Z-Wave® is an interoperable, lightweight wireless technology that empowers both consumers and
manufacturers with an ecosystem of products that work together.
This product can be included and operated in any Z-Wave network with other Z-Wave certified devices
from other manufacturers and/or other applications. All constantly powered nodes within the network
will act as repeaters regardless of vendor to increase reliability of the network.
2.2
Initial Inclusion
To start using a newly acquired ZiRC, set the STB into inclusion mode. Insert 2 AAA batteries as
indicated in the battery compartment of the ZiRC.
Any button press on the ZiRC will start learn mode. While in learn mode, the LED will blink amber every
3 seconds. After a few seconds, the LED should blink green 3 times on success or red on failure. Any
button press would exit the inclusion mode with failure.
After successful inclusion, the ZiRC waits 10 seconds for any association to be set up during which time
the LED should blink amber every 3 seconds. If any association was successfully set up during this time,
it will blink green thrice. Otherwise any button press or timeout would exit the association mode with
the LED blinking red thrice.
After this process the ZiRC goes to sleep and is now ready to control the STB. After any successful
exclusion or reset operation, any button press will enter inclusion mode.
2.3
Audio Video control
To switch the ZiRC between Z-Wave AV and IR mode, press & hold SETUP+RED for 1 second. The ZiRC
remembers the mode it is in even when its batteries are replaced.
On entering IR mode, the LED will blink amber once. All button presses are acknowledged by a single
amber blink, as there is no feedback from the STB for IR. Note that while in IR mode, only the switch
mode combo will work and all other combos are ignored.
