HARDWARE & MOUNTING

Connect the terminal to the installation.

Specify the bracket, antenna pair, cable routing, vehicle power protection and interface pinout as part of your installation.

No built-in battery; external power required
RS232 / RS485 / RJ45 interfaces
Heading requires a defined dual-antenna baseline

Power and interfaces

No built-in battery; external DC 9–24V input; datasheet adapter line: 3A / 27W

USB Type-A host ×2; Type-C ×1; RS232 ×1; RS485 ×1; RJ45; dual nano-SIM; microSD; 3.5mm audio

Battery capacity is not a runtime guarantee. Input and adapter ratings are not measured operating consumption.

REFERENCE TO FIELD

Connect to a reference source.

GB30 combines a local reference base and Caster. Use a suitable local or uplink source for the project and verify the client-side data path.

Before you decide

What will the quotation include?

Confirm the selected SKU, antenna, strap or bracket, power supply, software licensing and service terms in the quotation.

Does a recorded RTK Fixed screen guarantee the published accuracy?

No. Verify the actual reference coordinates, baseline, sky visibility, antenna setup, correction age and application requirements. The original specification statistics remain qualified in the table.

What is required for dual-antenna heading?

Confirm the two external antennas, mounting orientation, baseline, cable routing, receiver configuration and host interface. The 0.1° RMS heading specification is tied to a 1m baseline.
