For high-speed (HS488) operation, the following restrictions apply:
• All devices in the system must be powered on.
• Cable lengths must be as short as possible with up to a maximum
of 15 m of cable for each system.
• There must be at least one equivalent device load per meter of cable.
If you want to exceed these limitations, you can use a bus extender to
increase the cable length or a bus expander to increase the number of
device loads. You can order bus extenders and expanders from
National Instruments.
