Installing the Hp·HIL Accessories
The human interface to the Series 300/500 computer system is through
the HP-HIL of the HP 98700. Ensure that you do not exceed 1000 rna
total current on the HP-HIL loop. In any case, HP-HIL
will
address no
more than seven devices on one loop.
CAUTION
HP-HIL SUPPORTS UP TO 12 WATTS, ON
THE LOOP. IF THE LOOP IS OVERLOADED,
THE LOOP MAY FAIL DUE TO AN OPEN
FUSE IN THE HP-HIL CIRCUITRY.
Pascal and BASIC operating systems
will
not support HP-HIL through
the HP 98700H. HP-HIL must be installed through the HP-HIL connec-
tor in the rear panel of the Series 300 computer. Refer to the Installation
Guide for your computer for details.
