a1 and b1 are the incoming phone lines (e.g. outside line or private branch ex-
change).
a2 and b2 are used to connect a phone in series. In idle state, they are connected to
a1 and b1 via a loop current connector. a2 and b2 are disconnected as soon as the
modem occupies the line.
4.4 User Profile
The modem offers a choice of profiles:
¾Default factory setting:
The default factory settings enable you to achieve a fixed
defined basic state of the modem. Starting with this “ba-
sis”, you can customize the modem according to your re-
quirements.
¾User profiles 0 and 1:
You can save configurations in the user profile, which may be
re-used for certain purposes.
A part of the S registry is saved in each profile. In the descrip-
tion, the affected registries are marked with an “*” in the S
registry.

4.5 Configuration Software HSComm
The configuration of the modem takes place via AT commands which are entered
by a terminal program or a control program in the form of character sequences. For
a simple set-up, all basic functions of the HELMHOLZ modem 56k 4.1 can be en-
tered without knowing the individual commands and their parameters, using the
configuration software.
The software can be installed on all common Microsoft Windows operating sys-
tems. A terminal window to enter commands directly is available.
4.5.1 HSComm Operation
At the start or via the menu Device -> Read settings, HSComm verifies the connected
device and displays the device name and the firmware in the program window. By
default, only those settings can be selected which are implemented in the identi-
fied device.
The buttons in the right column can be used to select the current settings, to reset
the device to the saved settings (Reset), or to set the factory settings (default val-
ues).
The selected configuration of the parameters is only sent to the modem after you
click the button SEND.
File menu: Configurations can be saved as files and re-loaded at a later date.
When an error occurs while transmitting a configuration to the modem, these are
displayed in the Error menu.
Hitting the key F1 will automatically display a help window regarding the cur-
rently selected topic.

Helmholz Modem 56k 4.1 11
4.5.2 Initial operation using HSComm
4.5.2.1 Serial interface
Control/PC and the modem must be modulated via the following joint settings of
the serial interface:
¾Baud rate (Data transmission speed)
¾Format (Start bit, data bits, parity, stop bits)
¾Data flow control (Hardware/software handshake)
PC Settings
Serial interface settings of the PC (Interface menu) – the current settings are dis-
played in the message bar of the main window.
This setting must also be entered at the application (e.g. SPS), which is later con-
nected to the HELMHOLZ modem 56k 4.1.
Settings at the HELMHOLZ modem 56k 4.1
Handshake setting at the modem (Configure menu
Æ Modem):
Auto bauding: With the first AT command, the HELMHOLZ Modem 56k 4.1 recog-
nizes the baud rate and the format of the incoming data and configures itself ac-
cordingly. When the modem doesn’t receive AT commands but user data right
away, the last saved settings are kept.
If more data is available than what can be received by the modem, the handshake
will regulate the data flow.

12 Helmholz Modem 56k 4.1
DTR Behavior
The signal Data Terminal Ready (DTR) on the serial interfaces indicates that the
connected device (control, PC) is switched on, connected and ready for operation.
The HELMHOLZ Modem 56k 4.1 may react to the device being switched off or the
cable being removed.
Echo
With the setting Echo the modem sends each command back via the serial inter-
face. During terminal operation, this makes it obvious which commands are en-
tered.

4.6 Installation Instructions
Note: For the installation of the HELMHOLZ modem with the configura-
tion software HSComm, please also read Chapter 4.5.
Important Safety Instructions
When using the communication device and its accessories, the following
safety instructions must be observed at all times to prevent fire, electric shock
or personal injury.
1. The device may not be used in wet environments, damp rooms or close to
water, e.g. close to bath tubs, wash basins, sinks, wet floors or swimming
pools.
2. The device should not be used during a thunderstorm, as this could result in
electrical shock.
3. The device may not be used when smell of gas or gas leakage is apparent, to
prevent fire hazards or an explosion.
Please comply with these instructions!

cation, a driver may be necessary. Please find our current driv-
ers at the CD-Rom, or install the standard modem 56000 under
Windows.
6. Communication with the Modem
Now, start your communication program on the PC and set it
to the used COM interface. The modem will automatically ad-
just to the baud rate of your PC.
7. Communication Control via a Terminal Program
Perform a short test using your terminal program.
(TeraTermPro, ProcommPlus).

5Functions
This chapter describes the functions and settings of the HELMHOLZ Modem 56k
4.1. The settings can be selected and changed via AT commands, using any termi-
nal program (Hyperterminal, TeraTerm, etc.)
Alternatively, all common settings can also be comfortably performed via the con-
figuration software HSComm (see Chapter 4.5 "Configuration software HSComm”).
Usually, you will find a part of the configuration software with the according set-
tings in the respective chapter.

5.1.2 Save Configuration
If the modem configuration was adjusted to certain user
requirements, these settings can be saved in the user pro-
files 0
or 1.
Configuration changes will be lost after a RESET or restart if
they were not saved before.
5.2 Serial Data Transmission
5.2.1 Automatic Baud Rate Detection
For each received AT command, the modem automatically
performs an adjustment to the set baud rate, the number
of data and stop bits, and the parity.
The adjustment to the transmission speed on the phone
line is performed automatically, unless the settings say
otherwise. During the establishing of a connection both
modems attempt to achieve the joint fastest speed on the
phone line.
For an existing connection, the modem must first switch
to command mode.
You will receive the transmission settings …
E.g.: +MS: V92,1,300,48000,300,56000
This means that a connection between 300 and 56000 bps
was established, preferably according to V.92, depending
on the line quality and the abilities of the remote termi-
nal.

5.2.2 Data Buffer for Serial Data Transmission
The modem has a fast send and receive cache (so-called buffer) to
adjust the modem to the operating speed of the application. It is,
however, possible to deactivate this data buffering and switch to bit
direct mode.
When working with buffers, handshake is recommended to
avoid transmission errors.
5.2.3 Bit direct mode
Only for special, non-standard data formats
In bit direct mode, the modem has no influence on the transmis-
sion format. Data is transmitted without buffering.
Data compression or error correction will not work in bit direct
mode. Only the abort sequence - default +++ - is utilized by the
modem.
Configuration with HSComm:
AT\N1

5.2.4 Hardware Data Flow Control with RTS/CTS
Hardware Data Flow Control with the Modem (CTS).
Modem
RS232 Cable
CTS Line
Application
(E.g.: PC or control)
When the input buffer of the modem exceeds a certain fill state,
the modem will set the CTS line to OFF. This indicates to the ap-
plication not to send any data.
After the modem has operated the input buffer so far that the XON
buffer falls below a certain fill state, it switches the CTS line back
ON and reports to the application that it is ready to receive data
again.
5.2.5 Hardware data flow control with the application (RTS)
Modem
RS232 Cable
RTS Line
Application
(E.g.: PC or control)
The application sets the RTS line to OFF to request from the mo-
dem to interrupt the data transmission.
It will depend on the according application software if the RTS/CTS
lines can be operated.
The application sets the RTS line to ON to request data from the
modem.
Configuration with HSComm (settings according to the require-
ments):
