3.1.4 Transmit Power Levels/Frame Size
The 900 MHz data radios can be operated at 1 watt (30 dBm) or 0.250 watt (24 dBm). For most models, the default transmit
power is 1 watt.
For 2.4 GHz radios, the transmit power is fixed at 0.065 watt (18 dBm) and DIP switch 5 is used to set the frame timing. The
default position (OFF) sets the frame timing to 60 milliseconds. To increase throughput, set the frame timing to 40
milliseconds. For battery-powered devices, increasing the throughput decreases battery life.
Important:
Prior to date code 15341 and radio firmware version 3.6, the frame timing was 40 ms (OFF) or
20 ms (ON).
3.2 DIP Switch Settings for the Performance Gateway Radio Module
The 900 MHz radios transmit at 1 Watt (30 dBm) or 250 mW (24 dBm). The 250 mW mode reduces the radio's range but
improves the battery life in short range applications. For 2.4 GHz models, this DIP switch is disabled. The transmit power for
2.4 GHz is fixed at about 65 mW EIRP (18 dBm).
DX80 Performance Gateway ISM radio devices are defined with R1, R3, and R8 in the model number.

DXMxxx-xxR1 - DX80 Performance 900MHz
•
DXMxxx-xxR3 - DX80 Performance 2.4GHz

Important:
To adjust the transmit power on the Gateway radio, Banner recommends using the LCD menu
