15 maximum.
20 meters maximum or 2 meters per
device (whichever is less).
Byte serial, bit parallel asynchronous
data transfer using a S-line
handshake system.
Maximum of 1 megabyte-per-second
over the specified distances with
tri-state drivers. Actual data rate
depends on the transfer rate of the
slowest device connected to the bus.
Primary addresses: 31 talk, 31
listen. A maximum of 1 talker and
14 listeners can be connected to the
interface at given time.
In systems with more than one
controller (such as this instrument),
only one controller can be active
at any given time. The active
controller can pass control to another
controller, but only the system
controller can assume unconditional
control. Only one sgstern controller is
allowed.
