RawPattern ‘RawPattern’ contains the received and transmitted signaling
bits. The upper byte contains the received pattern while the
lower byte contains the transmitted pattern. Each of these bytes
contains only four significant bits. These bits contain the value
for signaling bits A, B, C, and D. Bit A is the most significant bit,
while bit D is the least significant bit.
For example, if ‘RawPattern’ contains 0x0F05, then the receive
pattern is 0x0F and the transmit pattern is 0x05.
Receive = 0x0F=1111, and A=B=C=D=1
Transmit = 0x05=0101, and A=C=0 and B=D=1
If you are transmitting signaling bits when using AccuSpan in
signaling mode, follow the same conventions.
Function ‘Function’ shows which function is currently running or which
function terminated last. You need to know the function name
in order to understand the terminating code listed in
‘TermType’.
The ‘Function’ field is particularly useful in finding out the
cause of
BRKT_ERROR_CODE(BUSY). This error means that the line
function specified by the ‘Function’ field was already running
when the application called another line function.
BRKT_ERROR_CODE(BUSY) is usually a result of a programming
error.
