DESCRIPTION
RedGTR - hydro-acoustic code communication modem.
The device uses a fixed-length signal with a code division to ensure the operation of a point-to-point network consisting of 25 devices, located in one water area.
RedGTR modems support up to 25 addresses - isolating code channels, 40 different code commands can be transmitted to each modem with a very high guarantee of reliability.
Ideal for controlling underwater actuators or for creating specialized acoustic releases.
Extremely small size, low power consumption, ease of use and high reliability make code modems RedGTR An ideal solution for controlling autonomous underwater devices.

1 A parameter that determines the maximum range at which a signal can be received, based on electro-acoustic parameters of the transmitter and receiver, spatial decrease in the intensity of sound energy, attenuation in the medium and the acoustic noise level.
2 In the version without a built-in pressure sensor, maximum depth is 400 meters
3 This value is obtained without the presence of the multipath effect
4 Can be changed by the special request
