Chapter B10 Programming with the DL900
software
Other methods of programming
You can program the system using the NX-1048 keypad or using the DL900 software. This software
allows you to download the programming information on the control panel to the computer running
the DL900 software, change it and upload the changes from the computer to the panel. It also allows
you to view the program log and event log. To program the system using this software, you must
connect the control panel to the computer.
Note: If you want to change the download access code, you have to do it both in the panel through the menu (Control
Panel>Communications>Up/Download>DL Access Code) and in the DL900 program (Control
Panel>Advanced>Download access>Access code), otherwise DL900 will use a default access code.
Connecting the panel to the computer
You can connect the control panel to the computer either directly via the RS232 serial port or
remotely via a modem.
Connecting using a serial port
Connecting via a serial port is useful if you are on site and want to connect directly to the alarm
system.
The connection to the NetworX V3 panel is made through the RS232 port using the NX-586E
module, which provides a standard RS232 bi-directional DB-9 connector. The NX-586E can be used
as a programming tool on any panel, as it is connected to the data bus. It stores control panel settings
that can be up/downloaded using the keypad or a computer. For more information on reading data
from the NX-586E, see Chapter B9 NX-586E.
To use the DL900 software with a direct connection:
1. Double click the icon for the software or click Start>Programs>Caddx>DL900.
2. The DL900 Download Software window and the Master access screen open.
3. Enter the operator name and password and click OK.
4. The Operator access screen opens.
5. Enter the current operator and password and click OK.
6. To connect to the panel directly via the serial port, select Download>Connect>Direct
connect using 586. The Connecting message box opens.
