KAPPA Telemetry Receiver Module
DS-KAPPA-T868-2
Range Considerations
The antenna choice and position directly affects the system range, keep it clear of any large
metal parts. The best position is protruding vertically from the top of the product. This is often
not desirable for practical reasons and thus a compromise may be needed. Note that the space
around the antenna is as important as the antenna itself. All radio systems are dependent on a
radio signal being received through airspace.
The range quoted is the optimal in direct line of sight without obstacles and in good atmospheric
conditions.
Range is affected by many things, for example local environmental conditions, atmospheric
conditions, interference from other radio transmitters. For evaluating the local environment
please see our RF Meter (DS006).
Mechanical Dimensions
Self Test Mode
The KAPPA module incorporates a self test which is initiated by applying power with the learn
button held down.
The KAPPA module then performs the following functions:
1.
All outputs operate in turn 1-4 ON/OFF twice
2.
All outputs flash ON/OFF 5 times - 1&3 and then 2&4
3.
Transmits a full power RF signal for 5 seconds while flashing the learn LED
4.
Enters RSSI (Received Signal Strength Indication) mode where outputs 1-4 are activated
as a bar graph type output according to the strength of a valid RF signal received (from
any carrier operating at the appropriate frequency (869.50MHz ). 4 Outputs on being
maximum strength.
5.
A reset will be required to exit
