Application and integration notes

The module requires DC 12 V input. Its listed mass is <55 g, and its envelope is ≤65 × 40 × 28 mm. Review these values against the host platform's power supply, mounting space and communications interface. For an integration inquiry, provide the target type, expected distance, atmospheric conditions and required update rate. Confirm the communications protocol, connector pinout and acceptance test before completing the system design.

Host-system acceptance

For the RS-422 connection, verify the command set, wiring and host-controller timing. Choose the measurement rate for the intended target and acquisition sequence, then verify valid measurements under representative conditions. Include both the nearest required distance and the long-range target in the acceptance plan.
