Figure 3-14: Default Pin Assignments for CPU COM Port Connector (RS-232).
Teledyne API offers two mating cables, one of which should be applicable for your use.

P/N WR000077, a DB-9 female to DB-9 female cable, 6 feet long. Allows
connection of the serial ports of most personal computers.

P/N WR000024, a DB-9 female to DB-25 male cable. Allows connection to the
most common styles of modems (e.g. Hayes-compatible) and code activated
switches.
Both cables are configured with straight-through wiring and should require no additional
adapters.
Note
Cables that appear to be compatible because of matching connectors may
incorporate internal wiring that makes the link inoperable. Check cables
acquired from sources other than Teledyne API for pin assignments before
using.
To assist in properly connecting the serial ports to either a computer or a modem, there
are activity indicators just above the RS-232 port. Once a cable is connected between
the analyzer and a computer or modem, both the red and green LEDs should be on.

If the lights are not lit, locate the small switch on the rear panel to switch it
between DTE and DCE modes.

If both LEDs are still not illuminated, ensure that the cable properly constructed.
Received from the factory, the analyzer is set up to emulate an RS-232 DCE device.
