The controller and the 1660-series logic analyzer must be in the same bit
mode to properly communicate over the RS-232C. This means that the
controller must have the capability to send and receive 8 bit data.

Technologies 1660-Series Logic Analyzer User’s Reference. For
information on RS-232C voltage levels and connector pinouts, refer to the
Agilent Technologies 1660-Series Logic Analyzer Service Guide.
RS-232C Bus Addressing
The RS-232C address you must use is dependent on the computer or
controller you are using to communicate with the logic analyzer.
HP Vectra Personal Computers or compatibles
If you are using an HP Vectra Personal Computer or compatible, it must have
an unused serial port to which you connect the logic analyzer’s RS-232C port.
The proper address for the serial port is dependent on the hardware
configuration of your computer. Additionally, your communications software
must be configured to address the proper serial port. Refer to your computer
and communications software manuals for more information on setting up
your serial port address.
HP 9000 Series 300 Controllers
Each RS-232C interface card for the HP 9000 Series 300 Controller has its
own interface select code. This code is used by the controller for directing
commands and communications to the proper interface by specifying the
correct interface code for the device address.
Generally, the interface select code can be any decimal value between 0 and
31, except for those interface codes which are reserved by the controller for
internal peripherals and other internal interfaces. This value can be selected
through switches on the interface card. For example, if your RS-232C
interface select code is 9, the device address required to communicate over
the RS-232C bus is 9. For more information, refer to the reference manual
for your interface card or controller.
