Panel Management
PictureFrame has two different formats for resolving Panel Links to albums:
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.
The Panel Link must either be Device:System or Device:Port:System:Code.
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
PictureFrame
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.
