Table of Hex Codes for Serial Communication

For delay times exceeding 127ms, you need to send two commands (eight
bytes).
The first command includes the most significant bits:
Byte 1 should be 63 (7FH)
Byte 2 should be 127 (80H) plus Most Significant bits of required delay
Byte 3 should be 127 (80H)
Byte 4 should be 127 (80H) plus machine number (from 1 up to 15)
The second command includes the less significant bits as described
previously for command 22.
Table 16 describes hex code examples for setting increased audio delay times:
Table 16: VS-44HC Hex Codes for increasing the Audio Delay Time
Delay Time for IN 1
[msec]
Command
128 7F 80 81 81
I6 81 80 81
130 7F 80 81 81
I6 81 82 81
200 7F 80 81 81
I6 81 C8 81
680 7F 80 85 81
I6 81 A8 81
To increase, for example, the IN 1 audio delay time by 1msec, the hex code
would be:
I8 82 8C 81
To decrease, for example, the IN 4 audio delay time by 1msec, the hex code
would be:
I8 84 8D 81
