Configuring the IN-tact 1101

Configuration Screens

 

 

Other models of modems may also work with the IN-tact1101. However, unlike supported modems, certain status screens may not accurately reflect correct values.

Within the IN-tact1101, 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-tact1101 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-tact1101

 

looks for the response to the attention command to determine the

 

modem's current state. Also, the IN-tactexpects 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).
