The bits are set in reverse order, from bit 15 on the left to bit 0 (zero) on the right. The bits are
grouped in four sets of four bits each, as such:
0000 0000 0000 0000
|................................|
bit 15.........................bit 0
Since each bit represents a setting, a bit can be enabled or disabled:
• 1 = installed option or enabled feature
– or –
• 0 = option not installed or feature not enabled
Enabling or disabling the bits in each group creates a binary value for that group. For example, if
the fourth bit in a group is set to 1, the group group's binary value is 0001.
Each group is translated into a hexidecimal equivalent. The group with the value of 0001 has a hex
equivalent of 1.
You can use this table to help with the conversion:

The hex value for each group is entered in the command as four digits.
To summarize the procedure:
1. Set each bit position.
2. Convert the binary value each group into its hex equivalent.
3. Enter the hex values for each group, in order, into the command for the value parameter.
The following example explains how the conversion is completed.
Putting the Terminal Command Together
For example, a unit only has the Remote Source Selection and Dual-Output Breaker options
installed.
Checking the bits list under Options_1 on page 75, bits 7 and 0 each must be set to 1 to indicate
that these options are installed.
The bit setting is as follows, starting with bit 15 on the left and going down to bit 0:
0000 0000 1000 0001
With the bits combined in groups of four, the binary settings can be translated into hexidecimal val-
ues.
The first two groups in the sample equal zero (0). In the third group, 1000 in binary translates to 8
in hex. In the fourth group, 0001 in binary translates to 1 in hex.
