Using an External Modem

Through the use of a standard, off-the-shelf modem
(capable of communicating at 9600 baud) and a
D9133DC connected directly to the control panel, RPS
can communicate with a D9412GV2 or D7412GV2 at
speeds of up to 9600 baud.
Both the U.S.Robotics V.92 56 K Modem
(model No. 5686, includes V.92 and V.90
56 K standard technology) and the Best
Data Smart One V.92/V.44 56 K External
Data/Fax Modem (model # 56SX-92) are
recommended for use as external modems
(connected to the control panel) based on
compatibility testing by Bosch Security
Systems. Other modules were not tested
or were incompatible.
The seven prompts on page 126 help to configure the
requirements necessary to connect an external modem
to a D9412GV2 or D7412GV2 Control Panel using a
D9133DC. This configuration allows communication
with RPS at 9600 baud because data is routed through
the SDI bus.
Use a separate phone line if an external
modem is being connected to the control
panel by a D9133DC Direct Connect
Programming Module. If obtaining a
different phone line from the line used by
the control panel is impossible, ensure that
the control panel is wired in front of any
premises phone and the external modem
devices so that full line seizure is
maintained. Also, ensure that the following
items are programmed in Section 2.7 RPS
Parameters on page 28:
•
Answer Armed = Blank or 0
•
Answer Disarmed = Blank or 0
•
RPS Line Monitor = No
•
RPS Call Back = No
•
RPS Phone number = Blank

When using an external modem, initialize it
using the following HyperTerminal
procedure on your computer. The
HyperTerminal procedures can vary,
depending upon the operating system.
®
1. In Windows , open the HyperTerminal
application. Select:
Programs→Accessories→Communications
2. Connect the modem to an available COM port.
3. With the modem connected, select the appropriate
COM port within HyperTerminal. Refer to
Figure 8 on page 124.
4. Set the baud rate of the modem to 9600.
For Best Data Smart One V.92:
Type [A][T][S][3][7][=][9][Enter]
For US Robotics:
Type [A][T][&][N][6][Enter]
For other modems, consult the instructions
provided with the device for the correct text
string.
5. Type [A][T][E][0][Enter]. This eliminates echo,
making all user input from this point forward
invisible on the screen.
6. Type [A][T][&][W][0][Enter] to write the
configuration to modem memory. The modem
profile is saved to a file upon disconnection or
power loss.
The external modem is connected to the D9133DC
Direct Connect Programming Module that is
connected to the SDI bus using SDI Address 88. Refer
to Figure 9 on page 124. A standard serial cable is
required to connect the D9133DC to the external
modem.
If you are using an external modem for RPS
communications, the enhanced
communications and RPS functions using a
NIM are disabled.
