CoMMunICAtIon ProtoCoL (ContInueD)
Example: $DSPKD,L1,4C31440D0C*47[CR][LF]
Top left key (L1) set to transmit “L1D\r\n” when pressed. ‘\r’ and ‘\n’ are escape sequences
for carriage return and newline characters.
Response: DSACK or DSNAK
DSPKu “Program Key up transmit Message” Command
The DSPKU Program Key Up Transmit Message command is used to program the message
a key will transmit when released (from Press). The data in Field 1 is encoded in a series
of ASCII character pairs representing hex bytes. For example, the ASCII characters “0102”
represent the two hex bytes 0x01 and 0x02; these two hex bytes transmit when the key is
released.
Example: $DSPKU,L1,4C31550D0C*56[CR][LF]
Top left key (L1) set to transmit “L1U\r\n” when pressed. ‘\r ‘and ‘\n’ are escape sequences
for carriage return and newline characters.
Note: Maximum key up transmit text is 20 bytes.
Response: DSACK or DSNAK
DSPKf “Program Key function” Command
Example: $DSPKF, L1, COMM*3B
Top left key (L1) set to cycle the video input
Response: DSACK or DSNAK
