TP1 | Flag bit mode: Flag bit can be used as an extra dataword. | Flag bit is is internally alternated by G-Link for enhanced error detection. |
TP2 | 20 bit G-Link mode | 16 bit G-Link mode |
TP3 | Link Synchronisation with on-board reference oscillator | Link Synchronisation with sync. pulses (Fill Frames) |
TP4 | Write only erroneous words | Write all received words |
The following setting must be used when this card is used with the Test
Data Source card:
TP1: Off
TP2: On
TP3: On (If this jumper is removed, the TSC must be reset to send sufficient
fill frames for the receiver to synchronise.)
TP4: It is up to the user to decide whether it is more convenient to
reveive all the data words and trigger on the words in error only (e.g.
with a logic analyzer) or receive only the erroneous word (e.g. with an
S-LINK destination system).
