Data Transfer (5E and DE) Commands
12. The switcher sends the last 200 bytes of data to the editor and indicates that
this is the last block by sending sequence number FFFEH:
The transfer is now complete.
Scenario 2
The editor is going to write Register Number 33 (21H) to Mix Effects 1. Note that
this time the editor is the transmitter of E-MEM data. The switcher is the receiver
and so it controls the transfer by specifying the sequence number of the next block
for the editor to send. To shorten the example, a register size of 635 bytes will be
used. The following dialogue is the result:
1. The editor sends the first block of data to the switcher:
2. The switcher requests the next block of data and supplies the sequence
number of this next data block to be sent. Implicitly this acknowledges receipt
of the previous block.
3. The editor sends the next block of data to the switcher:
4. The switcher requests the next block of data and supplies the sequence
number of this next data block to be sent:
