5.2 Between EntraGuard Network and Host Computer
A communication link between the EntraGuard network and the host computer is provided via one of two ways.
• using the phone line connected to TB-15
• using the RS-232 serial port
NOTE: In order for monitor mode to work, the RS-232 serial port method must be used (see Section 5.2.2 on page 14).
5.2.1 Phone line (Internal Modem)
The EntraGuard Titanium controller’s internal modem may be used for communication between the master controller and
an external modem

connected to the host computer. To use the EntraGuard’s internal modem, attach the phone line to
TB-15 located on the master controller’s board (see Figure 2 on page 2).
NOTE: If you are using two separate phone lines, one for communication with the tenants and one for programming, you
will not be able to use the internal modem for programming and must use an external modem connected to the RS-232 as
described in Section 5.2.2.2 on page 16.
Once the phone line has been attached, the J11 jumper must be set for proper operation. When using TB-15 phone line
connection for communication with the host computer, place the jumper on the INT_MODEM jumper (see J11 on Figure
2 on page 2).
The Doors software must also be configured for using the internal modem. In the Doors software, click on the
button, then select the Network Config tab. In the “Modem Init String” field type in AT&K0
