Control via API
The API manual is available to down load from:-
http://www.calibreuk.com/documents/vxl/VXL%20API%20Protocol_v1.40%20Generic.pdf
Please refer to this manual for detailed description of control parameters and for lists of codes for
each type of action required for remote control using either the RS232 port or the TCP/IP LAN port
Control via RS232 Remote Control Port
a.
Here is an example of how to use the API control information:-
1. Open HyperTerminal or similar application on your computer
Set the parameters for the serial port to:-
baud rate - 9600
parity - none
data bits - 8
stop bits - 1
2. Send an identify request string to see if the user can talk to the box. Send 16x A, i.e.
AAAAAAAAAAAAAAAA. If successful communication is established the answer VXL500HD is
returned.
3. This example is used to provide easily visible changes:-
To change the active input to 3G-SDI 2 send the following string: APC AAA2 AE AAAAAB A
This string is made up of the following:-
Please note that items ii. Iii. and iv. are listed in the API manual.
i. AP - always start the application string with these characters
ii. C - this is the function identifier, in this case:- C = set a value)
iii. AAA2 – this is the parameter identifier, in this case:-
AAA2 = select input )
iv. AE – this is the attribute, in this case:- AE = change it live
(Change it live means – change input but don´t store the change in the EEPROM. If the user wants
Fovea to remember this input then use the attribute AF instead)
v. AAAAAB - is the value in BASE64 alphabet
AAAAAA = 3G-SDI 1, AAAAAB = 3G-SDI 2, AAAAAC = Component YPbPr, AAAAAD = CVBS 1,
AAAAAE = CVBS 2, AAAAAF = S-Video, AAAAAG = DVI, AAAAAH = HDMI, AAAAAI = Analog,
AAAAAJ = Test Pattern.
In this case
AAAAAB = change to input 3G-SDI 2
vi. A - always end the string with this character
