R-1355 Wireless PDA Readout with Read9 Software


Hamar Laser’s R-1355 Wireless PDA Readout combines a Trimble Nomad PDA with a Zigbee® RF module operating at 2.4 GHz. The R-1355 Readout operates with Hamar Laser’s A-1519-2.4ZB and A-1520-2.4ZB radio wireless targets and any continuously rotating laser in our product line.

The radios employ 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 two or more systems can work in the same area and will not interfere with each other.

The R-1355 Readout comes with Hamar Laser’s READ9 alignment software (running under Windows Mobile® Version 6.0) pre-installed. The software displays readings for up to 4 targets in two user-selectable screens. Included are mode selections for alignment functions, such as setting a laser plane parallel to three points on a surface, graphic displays of the target readings, sample averaging to minimize the effects of air turbulence or vibration, and a data screen that summarizes the target readings.
