DB-9 Female
Note: Standard AT 9 Pin to 25 Pin adapter cables are not wired as shown above and will
not work with the Analyzer488. Order IOtech Part Number CA-47.
WARNING
The Analyzer488 makes its earth ground
connection through the serial interface cable. It
should only be connected to IEEE bus devices
after being first connected to the host. Failure to
do so may allow the Analyzer488 to float to a
bus device test voltage. This could result in
damage to the interface, personal injury or
death.
