Eachvendor must maintain its own list of product codes.Vendor ID(2 bytes)Each QCPort vendor must use their unique ID as assignedby Eaton Electrical.Serial Number(4 bytes)A device’s serial number must be reported. This value mustbe unique for a particular manufacturer across all devicetypes.Hardware Revision(2 bytes)Major revision must be reported in the MSB. Minor revisionmust be reported in the LSB.Firmware Revision(2 bytes)Major revision must be reported in the MSB. Minor revisionmust be reported in the LSB.QCPort Revision(2 bytes)Major revision must be reported in the MSB. Minor revisionmust be reported in the LSB.Size Description2 bytes Used for confirmation of a device’s configuration. Normally, the initial values of selected configurationparameters would be included in the calculation. The product instruction leaflet should describe whichparameters are actually included. To facilitate node replacement, Device Identity information should not beincluded in this calculation.Size Description2 bytes This parameter specifies a device’s Node ID. The Group ID is the Most Significant Byte and the Member ID is theLeast Significant Byte.An Initial Value of 0x0000 indicates an unconfigured state. In this state, a device assumes a current value basedon the level of switch support implemented in hardware.Size Description1 byte This parameter specifies a device’s operating mode, as follows:Size Description1 byte This parameter specifies the QCPort baud rate for a device as indicated below:0x00 — 9,6000x01 — 19,2000x02 — 38,4000x03 — 57,6000x04 — 115,2000x05 — 230,4000x06 — 460,800Note that the current value of the baud rate cannot be directly modified. The current value is set to the initialvalue upon reset. Therefore, writing to the initial value and resetting the device sets a new current value.Mode Description Active/Passive0x000x010x020x030x04UnconfiguredSimple SystemMaster/SlaveWire ReplacerFaultedPassivePassiveActivePassivePassive
