Cabling 

HP-IB  Cabling 

The recommended method for connecting an HP-m system is linear with the 
system controller at one end. However, an  HP-IB system can be connected 

together in a star, linear, or a combination configuration as long as the 

following rules are followed: 

• 

The total number of devices is less than or  equal to  15. 

• 

It is recommended that no more (han three cable connector blocks be 
stacked on top of one another to minimize stress on connector mountings. 

• 

The connector screws are designed to be tightened with fingers only. The 
screwdriver slots in the lock screws are for removal purposes  only. 

• 

For operation with  data  transfer rates less than 500 Kbytes/sec. the total 
length of the all cables used is  less than or equal to  2 meters times the 

number of devices connected together, up to a maximum of 20 meters. 

For example, the maximum cable length for 2 devices is 4 meters. The 

length between adjacent devices  is  not critical as long as the overall 

restriction 

is 

met. Systems should operate normally with up to one third of 

the devices powered off. Systems using older devices that do not use 

tri­

state drivers will be limited to transfer rates of less than 250Kbytes/sec. 

• 

For operation with data transfer rates over  500 Kbytes/sec, the total 

length of the all cables used is less than or equal to  1  meter times the 
number of devices connected together, up to a  maximum of  15 meters. 

You should minimize cable length as much as possible.  All devices must 
have tri-state drivers  and must be powered on. Few instruments are 

capable of running  at these speeds. 

• 

Turning a device  on or off while a system  is running may cause faulty 
operation. 

HP-lE bus extenders are  also available that will allow operation over much 

greater distances.
