Functional Description
The VMIVME-2533 transfers digital data from the VMEbus backplane to RS485/422
compatible differential output drivers. The board will support byte, word, and
longword data transfers. A simplified functional block diagram of the board is
illustrated in Figure 1 below.
The VMIVME-2533 is designed with extensive Built-in-Test electronics that enable the
user to test most of the circuitry on the board. When the VMIVME-2533 is in test
mode, data, which is written to the output registers, can be read back to verify proper
operation. This can be done without driving the output cable, and without disturbing
the field circuitry connected to the VMIVME-2533. Figure 2 below shows a simplified
diagram of the Built-in-Test features of the VMIVME-2533.

VMIVME-2533 Differential Digital Output Board

Functional Block Diagram
The VMIVME-2533 Differential Digital Output Board consists of VMEbus
compatibility logic, four 8-bit output registers, eight 4-bit differential line drivers, a
Control and Status Register, and eight 4-bit differential line receivers used by the
Built-in-Test logic, as shown in Figure 3 below.
The VMEbus compatibility logic controls data transfer allowing 8-, 16-, or 32-bit
VMEbus data transfers.
The four 8-bit output registers latch 32 bits of output data, which drives the eight
RS485/422 compatible differential output voltage drivers to the field connector.
The Control and Status Register (CSR) contains three bits. One bit controls the
on-board Fail LED, while the other two bits, along with some additional logic, control
the test functions of the board.
Built-in-Test logic enables the output data to be read back without affecting the signals
to the field. System reset puts the board into test mode for immediate loopback
testing.

Safety Summary
The following general safety precautions must be observed during all phases of the
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 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.
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 for service and repair to ensure that safety features are maintained.
Dangerous Procedure Warnings
Warnings, such as the example below, precede only potentially dangerous procedures
throughout this manual. Instructions contained in the warnings must be followed.
STOP: Dangerous voltages, capable of causing death, are present in this system. Use
extreme caution when handling, testing, and adjusting.

Operational Overview
The VMIVME-2533 consists of five primary sections as illustrated in Figure 1-1 below.
These sections are described in more detail in the following sections.
To perform an output data transfer, data is written into Output Data Registers (ODRs)
which latch the data. The latched data is used by the output driver stage of the board.

Figure 1-2 VMEbus Foundation Logic
Device Addressing
The VMIVME-2533 is designed to support data transfers in supervisory or
non-privileged short I/O memory space or both. A jumper (AM02) is provided as
shown in Figure 1-3 on page 18 (Address Decode Block Diagram) to allow user
selection of either I/O access type or both. The jumper (AM02) is factory configured
(jumper AM02 not installed) to respond to short supervisory I/O access. Refer to
Configuration and Installation on page 22 for a detailed explanation of the address
modifier jumper.
The VMIVME-2533 is designed with a set of board select jumpers and decode logic as
shown in Figure 1-3 below to provide an efficient memory address map for CSR and
output data addresses. The board is also designed to handle 8-, 16-, or 32-bit data
transfers. Figure 1-4 on page 19 shows the block diagram of this circuitry.
