Once the GUI has been accessed, the specific address of the register with the desired data must be
entered, and a read of the register executed. The data is in a 32 bit hex format which must then be
converted to a decimal equivalent. Information in the tables below will indicate what format the data
is in (generally signed or unsigned integer) and the units of the data.
As an example of how to convert the data to usable information, suppose that one wanted to know what
the Set point requested value was for channel 7. The BAR (Base Address Register) tells us that the
Channel Control Registers reside between address 0x00000000 to 0x000003C0. The EMCOR channel
registers table tells us that the base address for channel 7 is 0x000001c0. Since the channel settings
registers table shows us that the information we're looking for (Set Point Requested) has an offset of
0x00, we would enter the address 0x000001c0 into the GUI and request a read of the information in
this register. In this case the data in the register reads 0x000f4240. The channel settings register tells us
this data is a signed integer format with units of uA. When translated to decimal, the result is 1000000,
or the equivalent of 1amp, which is the current set point for channel 7.
