• Transmission conditions
This message is transmitted when either of the following conditions
are met.
• The "BULK OUT (ALL)" function is executed to perform a bulk
dump.
• A Bulk Dump Request message is received.
• Data conversion
The data portion is handled by converting seven words of 8-bit data
into eight words of 7-bit data.
