TZM883V
57 30 34 32 0D
whereas to set 1 second for all the outputs, the following hexadecimal characters must be
sent:
57 30 30 32 0D
The matrix replies:
ACK
(Hex 06)
NACK (Hex 15) if transmission errors have been detected
9.9 Connection status request
The host must send the following sequence:
D
1 control character (Hex 44) no other parameters are required
<CR>
1 end of string character(Hex 0D)
The matrix replies with a string indicating the status of the connections:
D
1 character that identifies the status requested (Hex 44)
vv
0 0
16 pairs of characters each of which indicates the number of the
1
...
video input connected to output n followed by the pair of
vv
0 0
n
characters "00"
The values of vv range from "01" a"08".
Note 1: if vv = "00" this means that the corresponding output is in
high impedance.
Note 2: In this case, the only function of the pair of characters
"00" is to make the reply comply with the standard of this
command, which is generic for all ELPRO matrixes.
<CR>
1 end of string character(Hex 0D)
Example: The host sends on line the following hexadecimal characters:
44 0D
A matrix that has all the inputs connected to the outputs of the same name will reply with
the following hexadecimal characters:
44 30 31 30 30 30 32 30 30 30 33 30 30 30 34 30 30 30 35 30 30 30 36 30 30
30 37 30 30 30 38 30 30 0D
