et, or so called Multi-drop bus commands. Multi-drop bus
commands give additional functionality to systems that require change of address for devices in cctalk network.
Some of commands has different message format than usual cctalk message.
Commands are:
- Address poll
-
Address clash
-
Address change
-
Address random
Because host always uses address 1 and address 0 is for broadcast message all commands that changes the address
should not accept this settings.
All changes are stored in non-volatile memory, EEPROM !

Command 253 [hexFD], Address poll
This is a broadcast message used by host to determinate all address of device attached on cctalk network. Coin selector
responds with only one byte (

address 2
)
AL06V-c
is:
Host sends:
[02] [00] [01] [FC] [01]
Coin s. responds:
Random Dly -> [02]
Address is 2
6.5.3.3
Command 251 [hexFB], Address change (not supported by coin acceptors)
Command Address change is issued to a specified device only. Coin selector responds with ACK message. Message
format is:
Host sends:
[Dir] [01] [01] [FB] [Address] [Chk]
Coin s. responds:

) change to address to 20:
Host sends:
[02] [01] [01] [FB] [14] [ED]
