SECTION 2 - INSTALLATION
2.1 UNPACKING AND INSPECTION
The Interface Card has been thoroughly inspected and tested prior to packing and is ready for
operation following installation. Unpack, saving original packing material. If any indication of
damage is found, file a claim immediately with the responsible transport service.
2.2 SET START-UP DEFAULTS (SEE FIGURE 2-1)
Start-up defaults, consisting of Device Address, Language, IEEE Cable Shield Ground State,
and Power Supply Identification are initially set by means of DIP switches as described in the
following paragraphs.
2.2.1 SET (GPIB) DEVICE ADDRESS (SEE FIGURE 2-1)
The Device Address for the interface card is initially set by means of DIP switch S1, positions 1
through 5 (Figure 2-1). The Device Address is the permanent Listener or Talker address of the
interface card on the GPIB. It is factory preset to address 6. If a different Device Address is
required in your system, proceed as follows. There are 31 (0-30) possible choices (See Table 2-
1).
1. Position the Interface Card as depicted in Figure 2-1.
2. The Device Address DIP switches are positions 1 through 5 (from bottom to top, Figure 2-
1). These switches are preset by Kepco to address 6. For other device addresses set them
according to Table 2-1.
2.2.2 START-UP LANGUAGE DEFAULT (SEE FIGURE 2-1)
DIP switch S1 position 6 sets the Start-up Language Default:
• 0 = SCPI (factory default)
• 1 = CIIL
2.2.3 IEEE CABLE SHIELD GROUND SELECTION (SEE FIGURE 2-1)
The interface card is shipped from the factory configured so that the IEEE cable shield will be
grounded to the BOP chassis. In some cases, however, it may be desirable to break this con-
nection to eliminate system “ground loops.” DIP switch S1 position 7 sets the Shield Ground
state:
• 0 = shield grounded (factory default)
• 1 = shield not grounded
2.2.4 SET POWER SUPPLY IDENTIFICATION SWITCH (SEE FIGURE 2-1)
Power Supply Identification switch S2 (Figure 2-1) identifies the BOP model to be controlled by
the interface card. Set Switch S2 positions 1 through 6 in accordance with Table 2-2.
