Description of the RFXPulse module.
The RFXPulse module measures
pulses from a Relay contact, Photo sensor or Reflective-Optical sensor.
The total measured
pulses are transmitted at predefined intervals.
The RFXPulse module must be
installed in the RFXMeter device. The RFXMeter device has 3 slots for RFXPwr
and/or RFXPulse metering modules.
The RFXPulse module consists of:
a microprocessor controlled pulse detection with selectable de-bounce.
Installation:
If there is no RFXPwr module installed in
the 1st location of the RFXMeter then a 9V (if DC then center is -) power adaptor must be used to power
the RFXMeter.
The pulse sensor is connected to the RFXPulse with a 3-pins Jack connector and 2
meter cable.
3 wires are use for the Reflective-Optical sensor. Ground, LED voltage and Photo
sensor signal. For a relay or photo sensor only 2 wires (ground and sensor
signal) are used.
The interval of the reporting can be changed by the user from 30 seconds, 1
minute, 6, 12, 15, 30, 45 or 60 minutes.
The address of the RFXPulse can be set by the user so that theoretically up to
256 units can co-exist.
The counter value of the RFXPulse is saved in non-volatile memory of the RFXMeter
device when a power loss occurs. The counters are restored when power returns.
The preferred receiver for the RFXPulse data is the RFXCOM X10 receiver. This
receiver can receive the full 48 bits data packets. The maximum number of pulses that can
be measured before the counter rolls over to zero is 16777215. The 48 bits
data packet enables a parity check on the received data.
The Homeseer RFXCOM plug-in supports the RFXPulse.
The Homeseer ACRF plug-in version 1.2.0.3 and up supports the RFXMeter with the
RFXCOM receiver only.
The W800 receiver can receive 32 bits and is therefore able to receive the first
32 bits of the data packet. These 32 bits contain the RFXPower unit address and
the lower 2 bytes of the measured pulses. The maximum number of pulses that can be measured
before the counter rolls over to zero is then 65535. A parity check is not
possible when the W800 is used and the configuration packets can not be received by the W800.
Capabilities:
2 pins Jack input for pulse sensors.
Selectable de-bounce time to suppress relay contact bounce.
The counter values are saved in non-volatile memory of the RFXMeter device.
Pulse counter value from 0 to 16777215. At the end the counter rolls over to zero again.
