03

Model-dependent power

Listed model ratings: 27, 30 and 33 dBm nominal. Confirm the measured maximum and factory limit for the selected unit.

04

Flexible data interfaces

Ethernet, RS232, TTL and SBUS connections vary by model. Refer to the model-specific table below.

Installation & safety notes
  • When an antenna port is receiving, the received signal strength must not exceed 10 dBm. Maintain the antenna separation specified for the installation; the source recommends more than 2 m between modules.
  • Provide continuous cooling to keep the core at or below 100 °C and the enclosure at or below 80 °C. Never exceed the supply-voltage limit of the selected model.
  • Power consumption values are measured at room temperature with a 24 V supply in continuous transmission mode; standby values are measured while connected without active service.
  • LAN is 10/100 Mbit/s. RS232 supports up to 115200 baud; 3.3 V TTL supports up to 460800 baud. Where specified, TTL/SBUS is software-configurable.
Configuration

Link configuration

  • Bandwidth choices: 1.25 / 2.5 / 5 / 10 / 20 MHz.
  • AES-256 air-interface encryption.
  • Dynamic frequency selection within a preset list.
  • Available nominal TX designations on this page: 27 / 30 / 33 dBm; measured maxima must be verified.
  • Configuration and network topology depend on the selected model and application.
