Safety Summary
The following general safety precautions must be observed during all phases of this
operation, service, and repair of this product. Failure to comply with these precautions or
with specific warnings elsewhere in this manual violates safety standards of design,
manufacture, and intended use of this product. GE Fanuc assumes no liability for the
customer’s failure to comply with these requirements.
Ground the System
To minimize shock hazard, the chassis and system cabinet must be connected to an electrical
ground. A three-conductor AC power cable should be used. The power cable must either be
plugged into an approved three-contact electrical outlet or used with a three-contact to two-contact
adapter with the grounding wire (green) firmly connected to an electrical ground (safety ground) at
the power outlet.
Warning
Do Not Operate in an Explosive Atmosphere
Do not operate the system in the presence of flammable gases or fumes. Operation of any electrical
system in such an environment constitutes a definite safety hazard.
Keep Away from Live Circuits
Operating personnel must not remove product covers. Component replacement and internal
adjustments must be made by qualified maintenance personnel. Do not replace components with
power cable connected. Under certain conditions, dangerous voltages may exist even with the
power cable removed. To avoid injuries, always disconnect power and discharge circuits before
touching them.
Do Not Service or Adjust Alone
Do not attempt internal service or adjustment unless another person, capable of rendering first aid
and resuscitation, is present.
Do Not Substitute Parts or Modify System
Because of the danger of introducing additional hazards, do not install substitute parts or perform
any unauthorized modification to the product. Return the product to GE Fanuc for service and
repair to ensure that safety features are maintained.

Caution
Some of the components assembled on GE Fanuc’s products may be
sensitive to electrostatic discharge and damage may occur on boards that are
subjected to a high energy electrostatic field. Unused boards should be
stored in the same protective boxes in which they were shipped. When the
board is to be placed on a bench for configuring, etc., it is suggested that
conductive material be inserted under the board to provide a conductive
shunt.
Upon receipt, any precautions found in the shipping container should be observed. All items should
be carefully unpacked and thoroughly inspected for damage that might have occurred during
shipment. The board(s) should be checked for broken components, damaged circuit board(s), heat
damage, and other visible contamination. All claims arising from shipping damage should be filed
with the carrier and a complet e report sent to GE Fanuc together with a request for advice about the
disposition of the damaged item(s).

Physical Installation
To install the board, de-energize the equipment and insert the board into an appropriate slot of the
chassis while ensuring that the board is properly aligned and oriented in the supporting card guides.
Slide the board smoothly forward against the mating connector until firmly seated. Review
“Configuration” on page 2-3 and “Before Applying Power: Checklist” on page 2-4 before operating
the board.
Caution
Do not install or remove boards while power is applied.

Configuration
This section of the manual describes the Digital-to-Analog Converter Board set-up procedure and
jumper configuration. The board select base address and board jumper configuration is factory
preset and shown in Table 2-1 below. The base address selection switches (S1 and S2) are factory
configured at XXXX0060 HEX.

Before Applying Power: Checklist
Before installing the board in a VMEbus system go through the following checklist to verify that
the board is ready for the intended operation:
1. Have the chapters on Theory and Programming of the DAC board, Chapters 3 and 4, been
read and applied to system requirements?
2. Review Table 2-1 on page 2-3 to verify the factory installed jumpers and board address
switches are set to what is desired.
To change DAC board switches (S1 and S2) refer to “Board Address Selection Switches”
on page 2-5.
To change address modifier response jumper (JB) refer to “Address Modifier Response
Selection” on page 2-7.
3. To change the DAC digital code selection refer to “Digital Code Selection” on page 2-8.
4. To use either the program controlled start convert mode or the external start convert mode
refer to “Program Controlled and External Start Convert Mode” on page 2-9.
5. Has the cable, with proper mating connector, been connected to the analog output
connector (P3)? Refer to “Connector Descriptions” on page 2-10.
Digital-to-Analog Converter Board Installation
After steps 1 through 5 have been reviewed, the DAC board may be installed in a VMEbus system.
(Do not install or remove the board with power ON). The DAC board may generally be installed in
any slot position, except slot "one" which is usually reserved for the master processing unit.

Board Address Selection Switches
There are two address select DIP switches on-board the Digital-to-Analog Converter Board. Each
individual switch corresponds to an address bit, or is not used. If the switch is ON the
corresponding address bit is compared to a logic "zero". All corresponding address bits must
compare with the switch positions during a Write/Read of the DAC board. Each switch corresponds
to the address bits as shown in Figure 2-1 be low. For the board switch locations are shown in
Figure 2-2 on page 2-6.
Example: For the Digital-to-Analog Converter Board to respond to a base address of
(FXFFBC40
) the S1 and S2 switches would be set accordingly.

Address Modifier Response Selection
The DAC board is memory mapped in the short I/O address space as described in Chapter 3. The
DAC board will respond to either of the two address modi fier codes that may be issued to the DAC
board by a CPU board during a Write or Read cycle. The DAC board is factory set to respond to
supervisory short I/O access. To select short nonprivileged I/O access, and install the jumper at
jumper location (JC).
