The PRU256 Programmer/logger is able to send and receive both standard and extended X-10 commands. You can use the PRU256 for logging X-10 data and noise present on the power line. On top of that the PRU256 is an easy tool for programming MicroModules. The PRU256 displays all information on its clear LCD screen. User friendly keyboard for easy operation.

Features

• Transmits and receives both standard and extended X-10 commands
• Displays noise level on the power line
• Displays signal level on the power line
• Log noise and signal levels over a 24 hour period
• Auto transmit mode for system testing
• Adjustable transmit voltage in 33.3mV increments
• Time/date (24 hour format)
• Selectable 0°, 30°, 60°, 90°, 120°, 150° transmit pulse
• Shows received X-10 packets as one frame or two frames: can be used to determine whether signal is repeated or original

Applications

• Programming tool for Marmitek 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)

Specification

• Supply voltage: 120 to 277 VAC (+/- 10%)
• Frequency: 50 Hz
• Current draw: 270mA at 240VAC/50Hz
• Receive Parameters: 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 120kHz ± 4kHz. The pulse width will be
  1ms ± 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-topeak strength into a power line with a 5Ohm load attached. The carrier frequency will be 120kHz ± 1kHz. The transmission pulse will be 1ms ± 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 power line 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).
• Display 16 Character x 2 Row LCD, bottom viewing angle. Contrast adjustment is possible with adjustment potentiometer on the right side of case.
