6 HF Data Modem 3112 User Guide
Overview
For ALE use, the modem is assigned a self
address. This is stored in the STANAG 5066
NOTE
Stack against the corresponding STANAG
address for the node. The self address for the
modem should be different from the self address
assigned to the transceiver.
Signal flow
For simple operation, the Codan HF transceivers must be
manually set to the same channel, and the modems must be
manually set to the same waveform. Data is passed from the
terminal session to the modem. It is processed by the modem
then sent to the Codan HF transceiver for transfer via HF to
any transceivers tuned to that frequency. At the receiving
node, the data is passed from the transceiver to the modem,
where it is decoded, ready for presentation at the remote PC.
Figure 1 on page 5 shows a typical layout for a data
communication system.
When the modem operates under the control of the STANAG
5066 Stack, the data may be transferred via an ALE link, or
via two transceivers manually set to the same channel. The
STANAG 5066 Stack requires a STANAG address to be set
for each node. Figure 2 on page 6 shows a typical layout for
an HF data communication network that uses Codan’s
STANAG 5066 Stack and HF Express
™
.
If a modem self address and ALE/CALM network is defined
against the STANAG address for the remote node in the
STANAG 5066 Stack, the Codan HF transceivers establish the
ALE link according to the information provided. If no modem
self address or ALE/CALM network is defined against the
STANAG address for the remote node, the transceivers must
be manually set to the same channel before the data is
transmitted.
The data from the PC is once again prepared by the modem,
sent via HF on the set channel to the specified STANAG
address, then passed to the modem for decoding and
presentation at the remote PC.
HF Data Modem 3112 User Guide 7

Overview
The Sync/Async Data connector provides a connection
between the modem and the PC by either:
• a COM port (asynchronous mode), or
• a synchronous card (synchronous mode)
The Ethernet connector provides a standard Ethernet
connection between the modem and the PC. This enables the
operator to control the transceiver, modem and data port via
terminal sessions. The data port operates in asynchronous
mode. The connector has two LEDs: one for LAN activity, the
other for the status of the link to the LAN.
The Transceiver connector provides the power, data and
control connection between the modem and the Codan HF
transceiver.

Operating the modem
General
When the 3112 HF Data Modem is used with the Codan
STANAG 5066 Stack, the modem and transceiver operate
automatically under the control of the stack. The stack selects
the most suitable waveform and appropriate settings for the
HF data communication.
When the modem is used without the Codan STANAG 5066
Stack, the transceiver and modem must be operated manually.
The HF link must be established via the handset or front panel
of the Codan HF transceiver. You must select an appropriate
waveform and settings for the HF data communication (see
page 59, Selecting a waveform).

Operating the modem
Operating the modem using controlling software
When the modem is connected to the PC via the Ethernet port,
or via three COM ports (3 asynchronous, or 2 asynchronous +
1 synchronous), you can communicate between nodes using
the Codan STANAG 5066 Stack.
The Codan STANAG 5066 Stack Control interface enables
you to set up the stack so that it controls the operation of the
modem and the transceiver. For information on how to use the
STANAG 5066 Stack Control interface see the on-line help
provided with the program.
Codan’s HF Express
simple chat and file transfer between nodes in an HF data
communication network. It must be used in conjunction with
Codan’s STANAG 5066 Stack. For information on how to use
HF Express see the on-line help provided with the program.
NOTE
™
is a software program that enables
If the transceiver and modem are directed to
make a call to a STANAG address for which
there is no ALE address information predefined in the STANAG 5066 Stack, the stack
proceeds with the data transfer regardless of the
state of the transceiver. Therefore, you must set
the transceivers at the sending and receiving
nodes to the same channel prior to transferring
data under these conditions.
58 HF Data Modem 3112 User Guide
Selecting a waveform
If the modem is under the control of the Codan
NOTE
If you are not using the modem with the Codan STANAG
5066 Stack, you must select an appropriate waveform for the
data communication. You must also check the settings
associated with the waveform. For more information on these
settings see page 67, Menu structures for waveforms and
page 60, Guidelines for manually selecting a waveform.
The STANAG 4539 waveform incorporates MIL-STD-188110A and MIL-STD-188-110B waveforms. Some Tx
interleaver values are not applicable for 110A and 110B,
depending on the transmit rate (see Table 4 on page 61).
NOTE
STANAG 5066 Stack during communication,
all waveform settings are determined by the
stack.
Although the values appear in the STANAG
4539 menu structure, they cannot be selected.
The modem selects the next higher Tx
interleaver value.
