Setting Up The PSI BOX
MODE 6
RS232 input to IEEE 488 output.
________
MODE 8
RS232 input to IEEE 488 output with talk back.
________
Allows HP IEEE plotters to fully emulate Rs232
version.
In mode 7, only available on the PSI BOX PLUS+, the PSI
BOX is the IEEE 488 controller. The RS232 port of the host
computer is used to control the IEEE bus. An enhanced
control language is used to address many IEEE devices and
to provide complete instrumentation control.
MODE 7
RS232 bi-directional to IEEE 488, full control of
________
IEEE bus of up to 14 instruments or devices.
