format) parameter type is used to send decimal values, and does not use a header. The
following examples show the proper parameter syntax for setting Bits B5, B3, and B2:
#b101100 Binary format (<NDN> parameter type)
#h2C Hexadecimal format (<NDN> parameter type)
#q54 Octal format (<NDN> parameter type)
44 Decimal format (<NRf> parameter type)
Valid characters for the non-decimal parameter values are shown as follows:
Reading registers
Any register in the status structure can be read by using the appropriate query (?) com-
mand. The following explains how to interpret the returned value (response message). The
actual query commands are covered later in this section (Table 14-3 through Table 14-7).
The response message will be a value that indicates which bits in the register are set. That
value (if not already binary) will have to be converted to its binary equivalent. For exam-
ple, for a binary value of 100101, bits B5, B2, and B0 are set.
The returned value can be in the binary, decimal, hexadecimal, or octal format. The
FORMat:SREGister command is used to select the data format for the returned value
(Table 14-2).
For non-decimal formats, one of the following headers will accompany the returned value
to indicate which format is selected:
#B = Header for binary values
#H = Header for hexadecimal values
#Q = Header for octal values
