Addressing

Each drive in the daisy-chained network has two addresses:

- Individual - for individual control of each drive. Its range is from 01h to 7Fh.
- Group - for simultaneous control of all group members by sending a single command to

their group address. It is in the range of 80h to FFh.

Both these addresses have to be set during the initialization process.

The group may have Group leader responsible to send status data. Its address is:

Group leader address = Group address - 80h.

If there is no group leader - no status data will be send after a group command.

Set Baud Rate

command must be sent only as a group command with no group leader, otherwise

communication problems may occur.

Setting the Addresses

After power-up and

Hard Reset

command all drives have their address set to 00h and only the first

drive (starting from the host) has its communication enabled. Consecutive

Set Address

commands

are sent to address 00h until all drives are addressed. This procedure can be executed once after

Hard Reset

. The table below shows the steps to address 3-drives network.
