I IMPORTANT SAFETY CONSIDERATIONS I
-
It is very important for the user to consider the possible adverse effects of
power, wiring, component, sensor, or software failures in designing any type
of control or monitoring system. This is especially important where economic
property loss or human life is involved. It is important that the user
employ redundancy, and comprehensive failure analysis to insure a safe and
satisfactory overall system design. It is agreed between the Buyer and
Acromag, that this is the Buyer's responsi
bi 1 i ty.

VMEbus ISOLATION BOARDS CHAPTER 2
PREPARATION FOR USE
This chapter provides information about preparing your board for system
operation.
2.1 UNPACKING AND INSPECTION
Inspect the shipping carton immediately upon receipt for evidence of'
mishandling during transit. If the shipping carton is severely damaged or
water stained, request that the carrier's agent be present when the carton is
opened. If the carrier's agent is absent when the carton is opened and the
contents of the carton are damaged, keep the carton and packing material for
the agent's inspection.
For repairs to a product damaged in shipment,
refer to the Acromag Service
Policy to obtain return instructions. It is suggested that salvageable
shipping cartons and packing material be saved for future use in the event
the product must be shipped.
The board is adequately protected with foam
though to visually inspect the board for ev
applying power.
2.2 CARD CAGE CONSIDERATIONS
Refer to the specifications for bus
1 oadinq
during shipment. It is adv
idence of severe handling pr
and power requirements. Be
that the system power supplies are able to-accommodate the additional
requirements within the voltage to1 erances specified.
i sable
ior to
sure
Adequate circulation of air must be provided to prevent a temperature rise
above the maximum operating temperature. Large and continuing fluctuations in
ambient air temperature should be avoided. If the installation is in an
industrial environment and the board is exposed to environmental air, careful
consideration should be given to air filtering.
2.3 BOARD CONFIGURATION
The Board may be configured in a variety of ways for many different appl
ica-
tions. Each possible jumper setting will be discussed in the following
sections. The jumper locations are shown in Figure 2.1.
2.3.1 Default Jum~erConfiauration
VMEbus INTERFACE CONFIGURATION
When a board is shipped from the factory, it is configured as follows:
- VMEbus Short 1/0 Address of 0000H.
- Set to respond to both Address Modifiers 29H and 2DH.
- Interrupt Level: none. Therefore, even if interrupts are enabled through
the Board Status Register, no interrupts will be caused. Interrupts are
available with analog inputs only.

2.4 VMEbus CONFIGURATION
2.4.1 Address Decode Jumper Confiquration
The board interfaces with the VMEbus as a 1K block of address locations in the
VMEbus Short 1/0 Address Space or Standard Address Space. 523 and 526 decode
the fourteen most significant address lines A10 through A23 to provide
segments of 1K address space. The configuration of the jumpers for different
base address locations are shown below. ("In" means that the pins are shorted
together with a shorting clip. "Out" indicates that the clip has been
removed.) 523 decodes Address lines A10 through A15 and 526 decodes Address
lines A16 through A23. Therefore when configured for the Short
I/O Address
space, only 523-needs to be configured.

2.5 ANALOG INPUT CONFIGURATION
( 935X-I & 9510-X )
2.5.1 Analoq Input T.me Jumper Confiquration
The board can accept either 16 channels of differential input or 32 channels
of single-ended input. The selection is made by configuring 56 and 516 as
follows (see Figure 2.2):

2.5.2 Analoq Input Ranqes Jumper Confiquration
16 Channel Differential
32 Channel Single-Ended
The Analog Input ranges may be selected through 518, 520 and 521. The basic
Analog Input Ranges are +10V Bipolar, +5V Bipolar and
OV to +10V Unipolar.
Other ranges may be obtained by changing the Software Programmable Gain (See
Board Control Register Description, Section 3.1.4) from
X1 to X2, X4, or X8.
Input ranges may be selected as follows:

The analog input data can appear as Unipolar Straight Binary (USB), Bipolar
Offset Binary (BOB), or Bipolar Two's Complement (BTC). The data format is
determined by the Analog Input Range (Paragraph 2.5.2) that is chosen and by
the configuration of J10.
