This camera complies with IIDC 1394-based Digital Camera Specification, Version 1.31 (hereinafter referred to as IIDC
v1.31).
The standards document can be purchased from 1394TA (the 1394 Trade Association). As it is very helpful in
understanding the explanations in this Technical Manual, we recommend that you purchase a copy of IIDC v1.31.

BusID
bbbbbbbb
1394 devices have a 64-bit address space. The upper 10
bits show the bus ID (0-1023), and the next six bits show
the node ID (0-63). The IIDC standards require the next
20 bits to be 1.
The remaining 28 bits can be allocated to the camera as
addresses.
The bus and node IDs may be changed if the topology is
restructured because of bus reset, so only the least
significant 32 address bits are shown in this Guide.
