Flexible Device Locations - Interlogix CDC4 Installation And Programming Manual

Flexible device locations

With the CDC4 Door Controller, there is flexibility in how devices such as inputs,
outputs and readers can be physically wired up to CDC4 and how they are
addressed.
Devices can be connected directly to CDC4 or can be connected to DGPs or
RASs on one of the CDC4 buses. Thus, when programming CDC4, devices are
not addressed by their number alone, but must be defined according to how they
have been physically wired up to CDC4.
When specifying a device attached to CDC4 in Downloader, the operator must
enter information in the following fields:
•
Location: Select the device location from the following options:
- On-board: The device is connected directly to the CDC4 on-board terminals
(or an output on an attached output controller). Enter the device number in
the Device number field.
- DGP: The device is connected to a DGP that is connected to one of the
CDC4 local buses. Enter the address of the DGP in the Address field, and the
device number on the DGP in the Device number field. The DGP must be
assigned to the CDC4 controller and polled on the bus.
- RAS: The device is a RAS, or is an input or output connected to a RAS,
which is connected to one of the CDC4 buses. Enter the address of the RAS
in the Address field. The RAS must be assigned to the CDC4 controller and
polled on the bus.
•
Address: If the device is connected to a DGP or RAS on one of the CDC4
local buses, then the address of this DGP or RAS must be specified.
DGP addresses from 1 to 15 are defined to be on bus 1, and DGP addresses
from 17 to 31 are defined to be on bus 2 (the DGP with address 16 is the
CDC4 controller itself).
Similarly, RAS addresses from 1 to 16 are defined to be on bus 1, and RAS
addresses from 17 to 32 are defined to be on bus 2.
There can be 30 DGPs and 32 RASs attached to CDC4.
•
Device number: The device number (address) of the device attached to RAS,
DGP, or CDC4.
The four on-board lock outputs are treated as the first four output numbers
assigned to CDC4. If an output is connected to CDC4 via an attached output
controller board, then the outputs are numbered from 5 onward. The number of
output controller boards must be configured on the CDC4 options tab of the DGP
form. See the "Output modules number" option on page 83.
If the Location is set to RAS or DGP, then the RAS or DGP must be assigned to
CDC4 using the Assigned RAS or Assigned DGP tab of the DGPs form,
respectively, and must be polled. See the "Assigned RASs tab" section on page
88, and the "Assigned DGPs tab" section on page 89 for more information.
