Cable Examples
HP 9000 Series 300
Figure 3-1 is an example of how to connect the 1660-series logic analyzer to
the HP 98628A Interface card of an HP 9000 series 300 controller. For more
information on cabling, refer to the reference manual for your specific
controller.
Because this example does not have the correct connections for hardware
handshake, you must use the XON/XOFF protocol when connecting the logic
analyzer.

Figures 3-2 through 3-4 give examples of three cables that will work for the
extended interface with hardware handshake. Keep in mind that these
cables should work if your computer’s serial interface supports the four
common RS-232C handshake signals as defined by the RS-232C standard.
The four common handshake signals are Data Carrier Detect (DCD), Data
Terminal Ready (DTR), Clear to Send (CTS), and Ready to Send (RTS).
Figure 3-2 shows the schematic of a 25-pin female to 25-pin male cable. The
following cables support this configuration:
•HP 17255D, DB-25(F) to DB -25(M), 1.2 me ter
•HP 17255F, DB-25(F) to DB-25(M), 1.2 meter, shielded.
In addition to the female-to-male cables with this configuration, a
male-to-male cable 1.2 meters in length is also available:
•HP 17255M, DB-25(M) to DB-25(M), 1.2 meter
