Notes: • Packets received must be sized to fit in a native ancillary data packet (i.e., payloads that span multiple ancillary packets need to be broken down by the
sending controller before they are sent to the device).
• Device can be configured to send back ACK packets each time data is inserted. The ACK packet is sent immediately after the data is actually inserted.
Packets need to be broken down by the sending controller before they are sent to the device. Device can also be configured to send out "heartbeat"
packets every two seconds as an additional safeguard.
• Packet formatting for insertion/extraction, ACK, and heartbeat is as follows:
