(Using the Handler Interface)
Modification of the Handler Interface
This section explains how to make the following modifications to the inside of the
instrument:
• Setting the drive/pull-up power supply between 5 V and 9 V or 15 V and 24 V.
• Mounting the pull-up resistors on the inside of the instrument.
NOTE The information given here is designed for Agilent Technologies service centers.
Setting the drive/pull-up power supply
The drive/pull-up power supply is set by using the jumper (J5) and DIP switch (S1) on the
A23 Handler Interface Board. For the location and socket numbers of J5 and the location
and switch numbers of S1, refer to Figure 12-5.
