2.5 System setup
The Detective is designed to work on any PC with a (16-bit) ISA slot. The PC does not have to
be equipped with a USB interface in order to work with the Detective analyzer. Two steps are
involved in the setup of the system hardware: connecting to the PC and connecting to the USB
system under test.
2.5.1 PC Connection
Turn off the PC power, and plug the Detective ISA card into any (16-bit) ISA slot in the PC’s
motherboard.
Connect the 15-pin cable between the CATC Detective Probe connector and the ISA card. Note
that both the USB Detective Probe and the USB Detective card use the same DB15 female
connector, which is similar to the standard PC graphic display VGA connector.
When external triggering initiation from the USB host software is desired, connect the external
trigger cable set between the USB Detective Probe header and the PC parallel port as follows
(see diagrams below):
•
Plug the 10-pin ribbon cable connector (included with the USB Detective package) into the
