R-1357-2.4ZB Wireless PDA Readout with Read16 Software


Hamar Laser’s R-1357-2.4ZB Wireless PDA Readout combines a Trimble Android PDA with a Zigbee® RF module operating at 2.4 GHz and Read16 Alignment Software. The R-1356-2.4ZB Readout  supports   our A-1519-2.4ZB and A-1520-2.4ZB radio wireless targets and any continuously rotating laser in  the L-730/L-740 Series products. When combined with our R-1307-2.4ZB Readout, it can also display the data for our 2-axis targets.

The Zigbee® radio employs a frequency-hopping protocol to avoid interference with other radio devices that might be operating at the same frequency. The radio allows the selection of different system IDs so that 2 or more systems can work in the same area and will not interfere with each other.

The  READ16 alignment software, using Android OS,  displays readings for up to five single-axis and two 2-axis targets. Included are mode selections for alignment functions, such as setting a laser plane parallel to 3 points on a surface, a laser setup wizard, graphic displays of the target readings for roll alignment, a data taking module, adjustable data averaging to minimize the effects of air turbulence or vibration, and a data screen that summarizes the target readings.
