RDM 600
Radio Data Modem
The RDM 600 is a rugged lightweight modem designed specifically for low power
consumption in harsh conditions. Developed initially by MASS as a key component
of the ATRACKS helicopter and ground data tasking system, the RDM 600 is a
bespoke modem designed to pass data through HF or VHF radios.

handshaking, radio
connections for remote configuration.
Synchronous data input is also supported
at standard RS232 signal levels.
Asynchronous

(Form 100A)
a standard
pre-keying and
A balanced 600-Ohm audio interface is
designed to connect
existing VHF and HF Clansman radios.
Input and output levels are adjustable
from 30mV to 2V. The radio keying
operates open circuit, short circuit
contacts capable of sinking 100mA.
Alternative audio interfaces to meet
other customer requirements
available.
Protocols
The RDM 600 currently supports the
Mil-Std 118-110A Single Serial Tone
and STANAG 4285
Alternative serial modem protocols to
meet customer requirements
externally programmable.

INTERNAL SPECIFICATIONS

The core of the RDM is run by a 16-Bit
fixed point DSP running at 75 MIPS.
The DSP can access up to 64K of
external SRAM and 8M bits of flash
memory and peripherals such as a 12-
Bit DAC, ADC and DUART.
