Details

Product dimensions: 27.30mm width, 43.94mm height. Key LED interface includes ANT, BAND-A/B, WORK, 5V pins. Precise measurements provided for assembly and integration purposes.

LED indicators display Band A (green), Band B (blue), and system status. Keys switch bands. Interface has 5V input, ground, 1Vp-p video output, and unused pins; reserved functions are inactive.

Key presses define frequency bands: Band-A uses green LED, Band-B uses blue. Each press count corresponds to specific MHz and blink count, from 1 to 8 presses per band.

Green and Blue LEDs flash per channel. Band A: 3330–3470 MHz; Band B: 3170–3310 MHz, each increasing by 20 MHz per channel across 8 channels.

Receiver specs include 3170-3470MHz frequency, 5V operation, -95dBm sensitivity, 480M IF-FRE, 0.8-1.2Vp-p video amplitude, 0dBm max input, and operating temps from -30°C to 85°C.
