Introduction
Thank you for purchasing a Codan 3112 HF Data Modem.
With this great product and Codan’s supreme after-sales
support, you can look forward to many years of reliable HF
data communication. Please read this guide thoroughly and
retain it for future reference. There is an index at the end of
this guide to assist you in finding information.
Overview of this guide
This guide is for technicians who install the hardware, and
system administrators who set up how the HF data
communication network interacts with other equipment. It
provides instructions on how to connect and set up a
3112 HF Data Modem with a Codan HF transceiver that is
capable of high-speed data transfer.
This guide assumes that the system administrator is familiar
with setting up HF communication networks for the Codan
NGT series Transceiver and 2110 Manpack Transceiver.
This guide contains the following sections:
Section 1 Overview—provides an overview of the
3112 HF Data Modem, how it is used within a
data communication network, how data flows
through the data system, the waveforms that it
uses, and a brief description of the front and rear
panels
Section 2 Installation and setup—describes how to
connect the Codan 3112 data system together,
how to set up the individual components of the
system, and how to test that the system is
functional
Section 3 Operating the modem—describes the modes of
operation, how to navigate through the menu
system, how to save profiles, and how to access
the on-board help

Overview
4 HF Data Modem 3112 User Guide
The 3112 HF Data Modem
The 3112 HF Data Modem provides a robust method of data
communication over an HF path.
A standard Codan HF data station (or node) comprises:
• a Codan HF transceiver that is capable of high-speed
data transfer
• an antenna system
• an appropriate 12 V DC power supply
• a 3112 HF Data Modem
• a PC with terminal software
A typical installation uses:
• an Ethernet connection between the PC and the modem
(see page 22, Connecting the modem to the PC via the
Ethernet ports), or
• three connections between COM and asynchronous/
synchronous ports on the PC and the modem (see
page 31, Connecting the modem to the PC via an
asynchronous port or page 38, Connecting the modem to
the PC via a synchronous port)
NOTE
The 3112 HF Data Modem can operate with a
standard data-capable Codan HF transceiver,
however it will operate below the optimum data
transfer rate of 9600 bps.

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.
NOTE
For ALE use, the modem is assigned a self
address. This is stored in the STANAG 5066
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.

The 3112 HF Data Modem indicates on its screen whether it is
transmitting, receiving or idle. For information on screens that
may appear see page 51, Screens.
Power supply
The 3112 HF Data Modem is powered via its connection to
the Codan HF transceiver. When the Codan HF transceiver is
switched on, the connected modem is also switched on.
Alternatively, the 3112 HF Data Modem may be powered via
an external DC power source that provides between 10 and
15 V DC.
Interoperability
The 3112 HF Data Modem supports the following waveforms:
• MIL-STD-188-110A
• MIL-STD-188-110B (serial tone)
• MIL-STD-188-110B (39Tone, parallel)
• STANAG 4539
• STANAG 4415
Operating modes
The modem has two operating modes:
•LOC mode: the modem is under local control
•REM mode: the modem is under remote control by the
Codan STANAG 5066 Stack

The Transceiver Control connector provides a connection
between the modem and a COM port on the PC. This enables
the operator to control the transceiver via a terminal session
using CICS. For information on using these commands see
CICS in the Reference Manual provided with the Codan HF
transceiver.
The Modem Control connector provides a connection
between the modem and a COM port on the PC. This enables
the operator to control the modem using in-built Remote
Control Protocol commands. For information on using these
commands see page 66, Using the on-board help in the
modem.
