BL118 App. boards
Issue 1, 05 November 2012
Bi-directional low power RF Remote Control boards
These simple application boards use
firmware based on the BD118 remote
control systems to implement a bi-
directional 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: BL118 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 4% duty cycle, 2 second burst cycle. The data format employed has an 8 bit address,
which is set up on a DIP switch (master and slave addresses must be the same)
LED indicators are provided for power, relay output state and "valid communication link established".
Features
8 bit address select switch
A relay to control mains powered devices rated up to 8A, 240VAC
Visual LED indication of communication status and relay state
Useful for RF module range testing
Logic or Switch input for momentary control of relay
Very low (1mA) average current. 2 years operating life from D cells
Simple “plug-and-play” setup. No complex programming needed
Applications
Security and Alarm systems
Emergency assistance call system
Status reporting and monitoring systems
RF Remote control systems
Industrial controls
HVAC controls
Simple On/Off switching
Long range telecontrol with Narrow Band FM radios
