							2 HF Modem ¸GM 2200
The multimode HF Modem 
¸GM 2200 is currently the most 
 advanced serial HF data modem and 
is fully integrated in the ¸XK 2000 
 radio equipment family. This modem 
can form the backbone of a fast and 
 reliable data transmission system. Thus large volumes of data such as fax, 
color video still pictures and electronic  
mail from PC to PC can be sent rapidly 
anywhere in the world. 
The software is available for the 
 following  waveforms:

STANAG 4529
MIL-STD-188-110 B,  App.  C/
STANAG 4539, Annex B, Section 4
These waveforms can be ordered in any 
combination, i.e. separately and inde-
pendently of each other, and enabled in 
the ¸XK2000.
Of course, they are interoperable with 
the corresponding waveforms of the 
 earlier ¸GM 2000 and ¸GM 2100 
modems, thus enabling problem-free 
communication with existing systems 
and with modems of other makes.◆

In conjunction with a system processor/
communication server and appro-
priate software and interfaces from 
 Rohde & Schwarz,  offi  ce  communication 
terminals such as fax machines, color 
video cameras/monitors or PCs may be 
connected and the associated data (in 
compressed form to save time) is trans-
mitted via shortwave.
A system with the HF Modem 
¸GM 2200 and a system processor 
coupled with ARQ-supported RSX.25 da-
ta protection yields 100 % error-free da-
ta when taking  all software error cor-
rection  facilities and data compression 
techniques into 
account. The transfer time for an A4-
size text page is only about 3 s to 6 s and 
that for a color picture including com-
pression less than half a minute, using 
the 5400 bit/s waveform.The waveforms constitute the basis for 
reliable and error-free HF data trans-
mission. An ARQ data link protocol en-
sures error-free data fl ow. Owing to 
our information technology and soft-
ware solutions such as COM2000 or 
 ¸PostMan II,  the   Rohde & Schwarz 
2700 bit/s and 5400 bit/s waveforms 
are used in connection with the ARQ 
RSX.25 protocol. Used for the ALIS 
or ALE link establishment method,  
this  protocol is specially adapted to 
the  Rohde & Schwarz 2700 bit/s and 
5400 bit/s waveforms.
However, waveforms in line with 
STANAG and MIL-STD such as the 
new 9600 bit/s high-speed waveform 
(STANAG 4539, Annex B, Section 4) can-
not be used together  with the RSX.25 
protocol. For these waveforms, radio pro-
tocols such as STANAG 5066 are avail-
able on request.The modem makes it possible to transmit 
data economically and reliably via short-
wave at high speed (up to 9600 bit/s) in 
contrast to traditional data transmission 
techniques such as radioteletype (RTTY) 
that allow 50 Bd or 100 Bd only.
