The Pc Ieee Subsets Supported - Brainboxes IE-340 User Manual

PC IEEE Reference
The PC IEEE board is capable of a maximum data transfer
rate of 250K bytes/second. The actual data transfer rate is
dependent on the PC's clock rate. On an 10MHz PC AT or 286
XT the maximum data transfer rate is 200k bytes per second, on
a 4.77MHz PC the maximum data transfer rate is 20K bytes per
second. Of course, the data is actually transmitted at the speed
of the SLOWEST addressed listener or talker. The positive 3
wire handshake ensures that data is transmitted correctly and
without loss.
The IEEE-488 Standard defines the following cabling
restrictions.
1). Not more than 20 metres between the most distantly
separated devices.
2). A maximum of 15 devices resident on the bus at the same
time.

The PC IEEE Subsets Supported.
