The controller and the HP 16500C Logic Analysis System must be in the
same bit mode to properly communicate over the RS-232-C. This means that
the controller must have the capability to send and receive 8-bit data.
See Also For more information on the RS-232-C interface, refer to the HP 16500C
Logic Analysis System User’s Reference. For information on RS-232-C
voltage levels and connector pinouts, refer to the HP 16500C Logic Analysis
System Service Guide.
RS-232-C Bus Addressing
The RS-232-C address you must use is dependent on the computer or
controller you are using to communicate with the Logic Analysis System.
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 Analysis System’s
RS-232-C 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-232-C 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-232-C
interface select code is 9, the device address required to communicate over
the RS-232-C bus is 9. For more information, refer to the reference manual
for your interface card or controller.
