PictureFrame
Panel Management
PictureFrame has two different formats for resolving Panel Links to albums:
Device:System
This option allows for any button on the panel to use that link. Device:System is a more
general option and is sufficient if there is only one dynamic image on the page.
Device:Port:System:Code
This option allows for more specific linking and is the correct way of handling multiple
dynamic buttons on the same page.
In order of request handling, the request built in TPD4 is parsed and put into a key string. An
example if the request arguments were:
device=10001&system=1&port=5&code=100
The key string would be 10001:5:1:100 and PictureFrame would try to find a Panel Link that
matches it. If no Panel Link was found, PictureFrame then drops back to try a link that matches the
device and system, in this example, 10001:1 . If a link is still not found, PictureFrame will serve an
image from the Default Album.
Adding A Panel Link
Images are served from PictureFrame to a panel via a panel link. To link an album to a selected
panel:
1. Select the album from the drop down list.
2. Go to Panel Links > Add Panel Link to open the Panel Link Entry Dialog.
3. Enter the Device number in the corresponding field. If certain buttons on a panel are intended
to have specific images it is necessary to provide port and code number for a more specific
Panel Link.
4. Click OK .
Device:Port:System (D:P:S)
A device is any hardware component that can be connected to the NetLinx bus. Each device must
be assigned a unique number to locate that device on the bus. The Axcess language allows physical
device numbers in the range 0-255. The NetLinx language allows numbers in the range 0-32767.
Device 0 refers to the master; numbers above 32767 are reserved for internal use.
NetLinx requires a Device:Port:System (D:P:S) specification where Axcess expected only a device
number. This D:P:S triplet can be expressed as series of constants, variables separated by colons, or
as a DEV structure, to explicitly represent a device number, port and system.
Here’s the syntax:
DEVICE:PORT:SYSTEM
where:
Device : 16-bit integer representing the device number
The Panel Link must either be Device:System or Device:Port:System:Code.
