Radio Description
The buoy system uses a 900 MHz spread-spectrum radio manufactured by Digi
International Inc. The radio network configuration is site-specific and usually involves
setting the following parameters.
Radio Settings Definitions
MK – Address Mask
The Address Mask is used with the Destination Address. The setting is 7FFF for the
buoy, controller, or repeater OUT. The setting is 8000 for the host modem radio or
repeater IN.
DT – Destination Address
The Destination Address is used with the Address Mask to establish Parent/Child
relationships and to determine which radios communicate with each other. Buoys—
8001, 8002, 800x; Controllers—8101, 8102, 810x; Repeater IN—7FFF; Repeater
OUT—8001, 8002, 800x; Host modem radio—7FFF.
ID – Modem VID
The Modem VID must be unique for each installation. This prevents radios from
communicating with radios at another location. However, radios with different VIDs may
still interfere with each other if they use the same hopping channel (HP).
HP – Hopping Channel (0-6)
The Hopping Channel defines a subset of the radio frequency range. Radios set with
the same hopping channel will communicate with each other. Radios set to different
hopping channels will not interfere with each other.
SM – Sleep Mode
Sleep Mode is used to put the radio in low power mode when not in use. Sleep mode is
set to a value of 1 (Pin Sleep) only on buoy radios. The SM setting must be set to 0 on
host modem and controller radios.
