Dual HP-IL adapter for HP-71B Message #1 Posted by Olivier (Wa) on 24 July 2007, 3:47 a.m. I just came accross this Dual HP-IL adapter HP82402A for HP-71B. Does anyone know what it is and what its purpose is ?

Re: Dual HP-IL adapter for HP-71B Message #2 Posted by Rodger Rosenbaum on 25 July 2007, 5:18 p.m., in response to message #1 by Olivier (Wa) It allows two HPIL modules to be controlled by a single HP71. As an example of its use, one could connect an RS-232 adapter to one of the HPIL modules, and some other device to the other. Then the output of a debugger (say) could be sent to a monitor connected to the RS-232, while the other device performance could be tested with the debugger, completely independent of the IL loop sending debugger output to the monitor.

I think the maximum I've had on the IL at once was six or seven devices. Edited: 26 July 2007, 3:41 a.m.
