Ultimately an optional specification refers to the event (state / signal) triggering the configured
fault action. The trigger, if enabled, can be based on two different and independent types of
event; that is, a specific internal protocol state and / or an external signal, fed thru the BNC
connector.
The trigger setup can be done by using the following selectors placed in a panel on the right-
end-side:
The external trigger is disabled / enabled by means of the specific 2-way selector
.
The internal trigger is instead enabled when one internal protocol state is selected; that is, one
different than the topmost selection (OFF) disabling the specific trigger use.
Referring to the protocol states, a list with a short description follows:
SP_RESET
DSL slave interface reset (protocol stack restart)
SP_SHOW_ID
Encoder ID sent to DSL master
SP_START
Waiting a vertical sync to enter SP_TX0...TX7 loop
SP_TX0
The 1
st
byte of the vertical channel (Summary) is generated
SP_TX1
…5
Refer to the absolute position (MS-
Byte…LS-Byte) slicing
SP_TX6…7
Refer to the CRC (15:0) of the vertical channel
