8. Polling Multiple KBU 64s
8.1 Introduction
Polling provides you with the ability to access the COMMAND ports of a
number of KBU 64s, from a single command console.
Up to 4 KBU 64s can be connected to the command console via a
Fivemere Port Sharer PSV4. These can be cascaded to provide support
for a total of 999 KBU devices. Refer to your PSV4 User manual for
details of the required connections.
Please see KBU 64 Rackmount User Manual 80-10100001 for details of
polling with the rackmount version.
