9.9 Computer Interface
Each CT-7000 has an RS-232C port, where the Breaker Analysis Software package provided
with each CT-7000, enables an IBM-compatible personal computer to communicate with the unit.
The software operating under Windows 95, 98, Me, 2000, NT and XP environments allow the user
to upload timing shots stored in the EEPROM into the computer. From the user's computer, the
user can now reanalyze the breaker’s timing shots and then output the timing reports through an
office printer. Since timing shots are stored in the office computer, users can create a database
of a breaker's timing history.
Follow the steps in Table 15.0 to put the CT-7000 under computer control:
