Status Operation
Get status
The operation to get the status fetches all the information about the topology and status
of the ALDV104T, its inputs, connections to ALV100R units, their status and that of the
attached screens.
The request to get the status is:
GET /status/tree HTTP/1.1
The response is an HTTP response containing a status code followed by headers and a
body containing a JSON encoded array of object.
A typical example of a response is:
[
{“ad”:”a”,”ln”:”ir”},
{“ad”:”b”,”ln”:”ir”},
{“ad”:”1”,”ln”:”hl”,”rx”:”nr”,”sw”:”1”,”t”:””},
{“ad”:”2”,”ln”:”hl”,”rx”:”nr”,”sw”:”1”,”t”:”HEDS”,“nd”:
”DELL<br>Descriptive text”},
{“ad”:”3”,”ln”:”hr”,”rx”:”nr”,”sw”:”1”,”t”:””},
{“ad”:”4”,”ln”:”hs”}
]
There are 6 objects of 2 types, and object is identied by the value of its “ad” attribute.
Input type
The rst two objects represent the 2 HDMI inputs. Each object has two attributes “ad”
and “ln”:
“ad” : “a|b” identies the port a = input 1 b = input 2
“ln” : “ir” input is red (disconnected / bad)
“ln” : “ig” input is good (connected / good)
Output type
The remaining 4 objects represent the 4 output ports and the ALDV100Rs and displays
connected to them. Each object has 2 attributes “ad” and “ln”, plus four optional
attributes “rx”, “sw”, “t” and “nd”.
“ad” : “1|2|3|4” identies the port 1 = output 1 .. 4 = output 4
“ln” : “hs” output is not in use
“ln” : “hl” output is connected
“ln” : “hr” output is not connected
“rx” : “nr” screen is not displaying signal
“rx” : “ng” screen is displaying signal
“rx” : “na” screen is in unknown state cannot be contacted (orange on display)
“rx” : “nb” screen is in disabled state (black on display)
“sw” : “1” screen is switched to input 1 (may or may not be displaying image, see “rx”)
“sw” : “2” screen is switched to input 2 (may or may not be displaying image, see “rx”)
“t” : “H” Hot Plug not detected from display
“t” : “E” EDID not successfully read from display
