RS-232C Interface
7.3 Communication Method
Communication is performed using commands from the PC and responses from the
tester.
One response is always returned for one command.
Commands cannot be sent continuously. Confirm the response before sending the
next command.
7.4 Talk Mode
The RS-232C on the tester has four talk modes.
Table 7-2 Talk modes
1
. The lower cutoff current is returned when the lower pass/fail judgment is enabled (“LOWER ON” is lit).
2
. The preset test time is returned when the timer function is enabled (“TIMER ON” is lit).
Processing on the PC is reduced in talk modes 1 to 3, since commands do not need
to be sent from the PC. In addition, by connecting a serial printer to the tester, these
modes allow the test log to be printed directly.
