Configuration Parameters

None of the Configuration Parameters support I/O data.

Table 43: 0x8001 (32769) Device Identity
Table 44: 0x8002 (32770) Configuration CRC
Table 45: 0x8003 (32771) Node ID
Table 46: 0x8004 (32772) Operating Mode
Table 47: 0x8005 (32773) QCPort Baud Rate
Size Description
14 bytes This read-only parameter contains information that uniquely identifies a device, including the following elements:
Product Code
(2 bytes) A device’s unique product code must be reported. Each
vendor must maintain its own list of product codes.
Vendor ID
(2 bytes) Each QCPort vendor must use their unique ID as assigned
by Eaton Electrical.
Serial Number
(4 bytes) A device’s serial number must be reported. This value must
be unique for a particular manufacturer across all device
types.
Hardware Revision
(2 bytes) Major revision must be reported in the MSB. Minor revision
must be reported in the LSB.
Firmware Revision
(2 bytes) Major revision must be reported in the MSB. Minor revision
must be reported in the LSB.
QCPort Revision
(2 bytes) Major revision must be reported in the MSB. Minor revision
must be reported in the LSB.
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.
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.
Size Description
1 byte This parameter specifies a device’s operating mode, as follows:
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.
