Connection instructions
The following figure shows a typical Model 2450-TLINK connection. When connected, you can use any of the six
TLINK lines to send or read TTL signals.
The following connection example controls measurements using TTL LO signals over lines 1 and 2. Configure the
Model 2450 to take measurements when a signal is read on digital I/O port pin 2; configure it to send a signal on
digital I/O port pin 1 when it is finished measuring. Configure the other instrument (the one with the TLINK
connector) to send the start signal on digital I/O port pin 2 and to read the completion signal from digital I/O port
pin 1.
You must configure which measurements the Model 2450 makes when triggered. You must also
configure the TLINK instrument to perform any needed actions before it triggers the Model 2450 and
any subsequent actions after it receives the completion signal.
Refer to the Model 2450 Reference Manual for specific trigger link, trigger model, and digital I/O
information. For configuration of the other instrument, refer its documentation.
