SATEL VERSA 21
Control panel settings
You can configure the modem communication settings:
 when programming the global parameters (see: “Global parameters” p. 26).
Description of parameters
Telephone numbers
Descriptions displayed on the LCD keypad are shown in square brackets.
Panel’s tel. no – telephone number of the control panel.
PC phone number [DLOADX tel.] – telephone number of the modem connected to computer
with DLOADX program installed.
DLOADX program settings
After clicking on the button you can configure the parameters of the modem connected
to computer (see: “Configuring the modem connected to computer”).
Dialing – the method of dialing numbers by the modem connected to computer (tone or
pulse).
Dial tones control – if option is enabled, the modem connected to computer will detect the
dial tone or busy signal before dialing the number.
Speaker – operating mode of the modem speaker. The speaker can be always OFF, or ON
until connection with the control panel is established (auto), or always ON.
Volume – volume of modem speaker.
Answering – how the DLOADX program reacts when the control panel is connecting to the
program. Communication can be established automatically after a preset number of rings,
or the program will only indicate an attempt to establish communication by the control
panel (communication will only be established after clicking on the “Answer” button).
Double call – you can define duration of the pause between the first and the second call, if
the control panel is set to go off-hook after the second call.
Configuring the modem connected to computer
You can edit the parameters after clicking on the “Change” button.
Port RS-232 – computer COM port to which the modem is connected.
Modem – list of modems, the parameters of which are defined. The list of modems and their
settings will be written to disk in the “modem.ini” file.
Baud Rate – transmission rate of the serial port. It is recommended that the highest rate
acceptable by the modem be set (only some modems may require the 300 bps setting in
order to enforce operation with exactly this speed).
Reset command – the command to reset the modem. Typically, it is the ATZ command
(reset with restoration of the user's zero profile). Some modems may require using the
AT&F command (reset with restoration of the factory default settings).
Initializing – lines containing the modem initialization commands. In the first line: E0V1Q0 –
a command required for proper operation of the modem. You should also add the
operating mode selection: B0 or B1 (selection of transmission format: V.21 or Bell103),
and the commands limiting transmission rate over telephone line to 300 bps. These are
commands specific for the given modem model, e.g. N0S37=3, F1 or +MS=1,0,300,300
etc. Information on how to limit the modem transmission rate is usually included in the
device manual. The other line should contain the following commands:
S0=0S9=1S7=120S10=255.
