HTTP string: Send from AlphaCom

HTTP GET via EDO Port

You can send HTTP GET to third-party systems using EDO ports and Event Handler.

Set up EDO port

In AlphaPro select Exchange & System > Serial Ports > Configure EDIO port

Port-Type: TCP/IP Client
IP-Address: destination IP
Port: destination port, usually 80 when HTTP.
Keep-Alive: off

Create Event

Use EDO command to send HTTP GET on the configured port.

Example using DAK 1 to send HTTP GET:

EDO 1 "GET /triggerevent?variable1=test1&variable2=test2 HTTP/1.1\r\nHost: 10.5.101.110\r\nConnection: Keep-Alive\r\n"
EDO 1 "Accept: */*\r\n\r\n"

A string generated by the EDO command can contain maximum 128 characters. If the http string exceeds this length, one can simply use multiple EDO commands.

Example: Control PTZ on an Axis camera

When pushing DAK 1 on an intercom station you want to pan an Axis camera 10 degrees to the left. Pushing DAK 2 should pan the camera 10 degrees to the right.

The http commands are:

• Relative pan : 10 degrees right

http://myserver/axis-cgi/com/ptz.cgi?rpan=10

• Relative pan : 10 degrees left

http://myserver/axis-cgi/com/ptz.cgi?rpan=-10

The camera IP address is 10.5.102.44.
