Table of Hex Codes for Serial Communication (RS-232/RS-485 Protocol)

Table 14 describes several examples for the hex codes used to set the delay

time:

IN 4

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 128 (80H) plus Most Significant bits of required delay
Byte 3 should be 128 (80H)
Byte 4 should be 128 (80H) plus machine number (from 1 up to 15)

The second command includes the less significant bits as described

previously for command 22.
Table 15 describes the hex code examples for setting the audio delay time for

delays more than 127ms:
