Figure 5-27 illustrates the WIN ECP configuration, which appears before the operator upon configuration of each
of the User Definable Registers (UDR). Using the computer’s arrow keys to select the field, and depressing the
space bar shall allow configuration of the fields within this popup menu screen.

Scaling Option and Destination Register Length Options Explained
The source data may be scaled from a 32 bit or 16 bit value from the relay to a 16,12,8,4,or 2, bit scale of the
value which is sent to a destination register. The scaling, minimum and maximum values sent to the destination
register are listed in the table below.

The above table lists the maximum and minimum values reported to a host in the scaled format. Table 5-10
illustrates the value correlation between the scale bit minimum and maximum numbers reported to the host
versus the unscaled values generated by the TPU2000 and 2000R.
