To Connect With the RS-232 Serial Interface
The Agilent 53150A, 53151A, and 53152A use an RJ12 modular connector
for the RS-232 interface. This connector is accessible through the back
panel of the counter, as shown in Figure 3-2.
Figure 3-2. Location of the RS-232 (RJ12) Connector
To connect the Counter to a computer using the RS-232 interface,
you need a serial cable that has an RJ12 modular connector at the
Counter end and a female DB25 connector at the computer end.
Making an RS-232 Cable
Most computers use male DB25 connectors for their serial ports.
Therefore, you must use either a cable with an RJ12 plug at the Counter
end and a female DB25 connector at the computer end or a double-ended
RJ12 cable and an RJ12-to-DB25F adapter to interface the Counter with a
computer. Since pre-manufactured RJ12/DB25 cables are rare, it is
probably most efficient to obtain the necessary parts, and assemble the
cable yourself.
