BD118 App. boards
Bi-directional RF Remote Control application boards
These simple application boards use
firmware based on the familiar CTA88
remote control systems to implement a bidirectional control link. A system consists
of a master board (which initiates
communication burst cycles) and a slave
(which responds to them). In hardware
terms these boards are the same, but have
different firmware loaded.
Figure 1: BD118 application boards
A single relay output is provided on each board, controlled by a logic (or switch) input on the "opposite"
board. This product only operates in one mode: the radio link operates continuously, and the output simply
reflects the state of the input ("momentary" operation).
The radio link uses a 10% duty cycle, 0.3 second burst cycle. The data format employed has an 8 bit
address, which is set up on a DIP switch.
LED indicators are provided for power, relay output state and "valid communication link established". (On the
"master" this LED is lit constantly if the link is functional. On the "slave" board this LED blinks on with each
burst received from the master)
Features
8 bit address select switch
A relay to control mains powered devices rated up to 8A, 240VAC
Visual LED indication of power, valid code received and active relay
RF module range testing
Logic or Switch input for momentary control of relay
Momentary relay output
Setup is simple as Plug-and-Play
