PRU 256 Programmer
and Logger |
 |
The PRU256
Programmer/logger is able to send and receive both standard X10 commands as
well as X10 extended commands. Keypad selections enable selection of
transmit signal levels, single or continuous signal transmission, user
selection of zero crossing degree shift and display or log the level of
noise or signal on the power line on the PRU 256 Liquid Crystal Display
(LCD). |
|
Features |
|
- Transmits and Receives both standard as
extended X10 commands
- Displays noise level on the power line
- Displays signal level on the power line
- Can log noise and signal levels over 24h
period
- Auto transmit mode for system testing
- Adjustable transmit voltage in 33.3 mV
increments
- Time/Date (24h format)
- Selectable 0°, 30°, 60° 90° 120° 150°
transmit pulse
- Shows received X10 packets as one frame
or two frames: can be used to determine whether signal is repeated or
original
- Can be used as P1 test transmitter when
combined with the X10 XPTR test receiver (Art.No. 09103)
|
|
Applications |
|
- Programming tool for X10 MicroModules
- Display signal strength on line from
other transmitters and two-way receivers
- Use to test potential installation sites
for possible installation problems
- Pinpoint loads to be filtered by logging
power grid noise levels (user defined time periods up to 24 hours)

The PRU256 will accept power line carrier transmission signals with minimum
strength of 25mV peak to peak. The carrier frequency of this signal will be
120 kHz ± 4kHz. The pulse width will be I ms ± 10% and occur no later than
200ms after the zero crossing of the main voltage. |
|
Transmit Parameters |
The
PRU256 will output power line carrier transmission signals with a minimum of
6V peak to peak strength into a power line with a 5 Ohm load attached. The
carrier frequency will be 120kHz ± 1 kHz. The transmission pulse will be 1
ms ± 10% and will start no later than 200ms after the zero crossing of the
mains voltage and when enabled an additional pulse will be transmitted no
later than 200ms after the 30* point of the half wave. |

Transmit Locations |
All transmission
locations (0° 30°, 60°, 90°, 120° & 150° can be individually activated or
deactivated through the SETUP menu.
NOTE: More than four activated transmit locations may deliver unsteady
transmit level results.
NOTE: The 0' transmit location must remain enabled if the automatic level
adjustment is to remain active. If the 0* transmission is disabled, the
circuit will always adjust to maximum level. |
|
Transmit level |
The level of the
powerline carrier transmissions can be adjusted through the setup menu. When
the level is set from 0 to 150 the Automatic level adjustment will be
active. This will readjust the signal level for line loading conditions. The
maximum adjustable level is 5V peak to peak (level settings of 150). Any
setting above this will result in a maximum output (>/= 6V peak to peak). |

adjustment potentiometer on the right side of case. |

PROGRAMMING |
|
Setup
Restart the PRU256 by holding the “0” key for at least 3 seconds. Press
PAUSE key when Version number information appears in the LCD screen. Now you
are able to choose one of the following options: |
- TX voltage: height of transmission
level
- TX location: Activation of transmission
locations (0°, 30°, 60°, 90° 120° & 150°)
- Date and Time
- Clear Logs
- Exit
