 ==Selecting device address==
-When accessing drive through [[SimpleMotion V2]] bus, each device in the bus should be assigned to different address between 1 to 32. Device address is a sum of hardware setting and software parameter {{param|SMO}}. The address of device is determined at the moment of logic voltage power on and will become by sum of hardware setting and SMO.
+When accessing drive through [[SimpleMotion V2]] bus, each device in the bus should be assigned to different address between 1 to N. Device address is a sum of hardware setting and software parameter {{param|SMO}}. The address of device is determined at the moment of logic voltage power on and will become by sum of hardware setting and SMO.
 ===Software selecting address===
 When having more than four devices in the same bus, or for example chaining multiple [[IONICUBE 1X]] motherboards (where all of them have address 1), it is necessary to utilize software parameter {{param|SMO}}. Procedure for setting unique address for each device with SMO:

 When having more than four devices in the same bus, or for example chaining multiple [[IONICUBE 1X]] motherboards (where all of them have address 1), it is necessary to utilize software parameter {{param|SMO}}. Procedure for setting unique address for each device with SMO:

+#Disconnect or unpower all other devices that the ones with already unique address (i.e. have only one IONICUBE connected to SM bus, or powered on)
 #Connect to drive with Granity
 #Adjust SMO parameter value so that device will receive a desired bus address. I.e. if using IONICUBE 1X, set SMO values 0, 1, 2, 3 to the different drives (drive addresses will become 1, 2, 3, 4). Or when IONICUBE (4 axis) is being used, set SMO values of drives on the first board 0, second board 4, third 8 etc (drive addresses will become 1 - 12).
