7 Host Controller Configuration Examples

The following are some specific examples of using registers to clear an error condition, change device I/O parameters, and
initiate a Site Survey.

7.1 Clearing Error Conditions Using Register Commands

All non-zero messages must be cleared by the user from either the Gateway or the host system.
The Gateway stores only the highest priority message in the register. A 0x00 message is not saved unless there is a 0x00 in
the I/O point register. To disable all error reporting, send a value of 254 in the register for I/O point 8. To clear any I/O point
8 device message, use the Gateway's front panel menu system. A host connection can also choose to clear or disable I/O 8
registers. Nodes ignore error messages.

05 Node 01-47
06 Node 01-47

7.2 Setting the Sample Rate

The sample rate establishes how often the Sure Cross device samples the sensors connected to it.
To set the sample rate to 900 seconds (15 minutes) on I/O point 1, Node #2, two register writes are required: register 47 and
register 48 (Node 2's register 15 and 16).
1. Write the parameter data (900 seconds = 14400 62.5 millisecond intervals = 0x3840) into register 48.
2. Write the parameter control code (write I/O #1 = 129 = 0x81) and the parameter number (sample interval = 0x03) into
register 47. Concatenated, the register value is 0x8103.

3. Read register 39 to verify the message is completed.

Verify the transaction is completed by reading register 39 and verifying the parameter control code and parameter number
match the intended action.

7.3 Setting the Counter Preset using Register Commands

The event counter input is a 32-bit value that can be preset using the parameter control codes 143 (0x8F) and 144 (0x90).
Parameter control code 143 writes the lower half [15:0] of the counter and code 144 writes the upper half [31:16] of the
counter.
Select which counter to preset by defining the Counter Select Mask. The first bit position of the mask (bit 0, right justified)
selects the first counter and the second bit position selected the second counter. Set the Node's register 16 to the high or
low data value. Read Node register 7 for the transfer acknowledgement. Write to Node register 16 before writing to Node
register 15.

Restrictions Description
Gateway only Reset error of Node # (defined by the data field). Control code available only on the
Gateway I/O 15 register. (This results in a 00 placed in the register I/O 8 of the
appropriate Node)
Gateway only Ignore error of Node # (defined by the data field). Control code available only on the
Gateway I/O 15 register.
Gateway only Disable Error of Node # (defined by the data field). Control code available only on the
Gateway I/O 15 register (This results in a 254 placed in the register I/O 8 of the
appropriate Node). Reset using the Reset Error function (04)
