Configuring the IN-tact 1101 Configuration Screens
28 Hypercom Corporation
Other models of modems may also work with the IN-tact 1101. However, unlike supported
modems, certain status screens may not accurately reflect correct values.
Within the IN-tact 1101, availability of the Ethernet port is constantly monitored. Once dial backup
is enabled, any outage of the Ethernet port lasting longer than 5 seconds automatically triggers
the IN-tact 1101 to switch to dial backup mode. Likewise, dial backup is automatically
disconnected (based on a period of inactivity you specify) once the Ethernet connection is
restored.
This screen allows you to configure basic modem operation. Use the Advanced button to display
additional modem configuration options.
Field/Button Description
Enable Dial Backup Click this checkbox to enable dial backup operation. By default, this
operation is disabled.
AT Initialization String Enter the initialization string for your modem. This string is sent to the
modem every time dial backup starts. This string is sent to the modem
every time dial backup starts. Up to 128 characters are accepted in
this field. At a minimum, you must specify at least the command AT
here; you cannot have a blank initialization string. The IN-tact 1101
looks for the response to the attention command to determine the
modem's current state. Also, the IN-tact expects a numeric response.
You must include the command V0 in your initialization string to
require a numeric response from the modem.
Consult the manufacturer's documentation for your specific modem to
determine the command set being used and what commands are
accepted by the modem. Reset to Default can be used to reset the
initialization string to the default US Robotics modem setting of:
ATE0V0Q0&C1&D2&K0&M4X4
If you are using a Hayes or ZOOM modem, the initialization string
should be set to:
ATE0V0Q0&C1&D2&K3&Q5W2
AT Hang Up String This is similar to the initialization string, except this command string is
sent to the modem to cause it to hang up. Enter the hang up string for
your modem. Up to 20 characters are accepted in this field. Consult
the manufacturer's documentation for your specific modem to
determine the command set being used and what commands are
accepted by the modem. Reset to Default can be used to reset the
hang up string to the default setting of “ATH0”. This default can be
used for all supported modem types. Any additional commands you
want to add to the string should be placed after the AT and before the
H0. Any commands entered as part of the Hang Up string are
automatically prefixed with “+++”.
Enable Primary Dial Click this checkbox to enable the primary dial string. This is the first
host processor that the modem will attempt to contact in the event of
an Ethernet outage.
Primary AT Dial String Enter any commands and the phone number to dial in order for the
modem to establish contact with the primary host processor. Up to 32
characters are allowed in this field. This string must begin with ATDT
(or ATDP for pulse dialing).
