Safety and Compliance

Before you use the Trimble Catalyst DA2 GNSS receiver, refer to the safety documentation and compliance information at: geospatial.trimble.com/DA2-Compliance

Attaching the Receiver to a Surveying Pole

The DA2 receiver has a convenient push-fit mount for simple attachment to any 1 ¼" diameter pole. A 5/8” x 11 thread adaptor for convenient installation/removal on standard mapping and surveying accessories is also included in the box.

Additional mounting accessories are available from Trimble or third party accessory vendors. Contact your Trimble distribution partner for details. Optional Trimble accessories include: A DA2 mounting accessory kit that includes: Short ¼" push-fit thread adapter for camera tripods and monopoles; Tall and short 5/8" x 11 lock-fit thread adapter for vehicle or high-vibration use; Replacement push-fit mounting kit; Aluminium and carbon-fiber survey poles and accessories.

For Consistent and Accurate Results

If using the receiver on a pole, ensure that it is flat and secure on the pole.
If using the push-fit 5/8" x 11 thread adapter, ensure that the yellow plastic of the thread adapter is completely concealed in the push-fit mount.
When you are ready to work, always position the receiver vertically above the point on the ground being surveyed or mapped.
When setting the receiver height offset in the field application (if supported), measure from the bottom of the push-fit pole mount to the ground.
When tracking satellites, try to always hold the receiver above head-height, level to the sky, and as vertical as possible to ensure best performance.

Assembling the Battery Mount

The DA2 receiver is powered by USB. You can attach a standard off-the-shelf single-cell USB power pack to a survey rod using the supplied battery mounting bracket and rubber straps. The supplied battery mount is designed to fit a variety of range pole and USB battery pack sizes.

To Assemble the Battery Mount

Stretch the two rubber straps over the plastic bracket.
