Configuration Parameters

None of the Configuration Parameters support I/O data.

Table 43: 0x8001 (32769) Device Identity

Size	Description
14 bytes	This read-only parameter contains information that uniquely identifies a device, including the following elements:
	Product Code				A device’s unique product code must be reported. Each
	(2 bytes)				vendor must maintain its own list of product codes.
	Vendor ID				Each QCPort vendor must use their unique ID as assigned
	(2 bytes)				by Eaton Electrical.
	Serial Number				A device’s serial number must be reported. This value must
	(4 bytes)				be unique for a particular manufacturer across all device
					types.
	Hardware Revision				Major revision must be reported in the MSB. Minor revision
	(2 bytes)				must be reported in the LSB.
	Firmware Revision				Major revision must be reported in the MSB. Minor revision
	(2 bytes)				must be reported in the LSB.
	QCPort Revision				Major revision must be reported in the MSB. Minor revision
	(2 bytes)				must be reported in the LSB.
Table 44: 0x8002 (32770) Configuration CRC
Size		Description
2 bytes		Used for confirmation of a device’s configuration. Normally, the initial values of selected configuration
		parameters would be included in the calculation. The product instruction leaflet should describe which
		parameters are actually included. To facilitate node replacement, Device Identity information should not be
		included in this calculation.
Table 45: 0x8003 (32771) Node ID
Size		Description
2 bytes		This parameter specifies a device’s Node ID. The Group ID is the Most Significant Byte and the Member ID is the
		Least Significant Byte.
		An Initial Value of 0x0000 indicates an unconfigured state. In this state, a device assumes a current value based
		on the level of switch support implemented in hardware.
Table 46: 0x8004 (32772) Operating Mode
Size		Description
1 byte		This parameter specifies a device’s operating mode, as follows:
				Mode	Description	Active/Passive
				0x00	Unconfigured	Passive
				0x01	Simple System	Passive
				0x02	Master/Slave	Active
				0x03	Wire Replacer	Passive
				0x04	Faulted	Passive
Table 47: 0x8005 (32773) QCPort Baud Rate
Size		Description
1 byte		This parameter specifies the QCPort baud rate for a device as indicated below:
		0x00 —	9,600
		0x01 —	19,200
		0x02 —	38,400
		0x03 —	57,600
		0x04 — 115,200
		0x05 — 230,400
		0x06 — 460,800
		Note that the current value of the baud rate cannot be directly modified. The current value is set to the initial
		value upon reset. Therefore, writing to the initial value and resetting the device sets a new current value.
