Hex Chart Use the Hex Chart to translate bit values to a hex value.

Relay Status

Example

For example the bit representative of the Relay status byte when set-

point relays 8,5,3, and 1 are on is (01101001). This eight bit value is

represented by two four bit nibbles (0110 and 1001). Looking at the

table we see this is equal to a Hex value of 69.
