1 Product Description
The TVME201 is non-intelligent 6U VMEbus Carrier for up to 4 single-size or two double-size
IndustryPack (IP) modules used to build modular, flexible and cost effective I/O solutions for
applications in process control, medical systems, telecommunication and traffic control.
The TVME201 is designed in accordance to VMEbus Specification ANSI/VITA 1-1994 and the
IndustryPack Logic Interface Specification ANSI/VITA 4-1995. It guarantees compatibility with the wide
range of IndustryPacks in a VMEbus system.
IndustryPack I/O and ID spaces are mapped into the VME A16/D16 space.
IP Memory spaces are mapped into the VME A24 or A32 space. D08 and D16 accesses are
supported. If mapped in the VME A24 space, the size of the required memory space is configurable. In
VME A32 space, there is a fixed space of 8 Mbytes for each IP module.
Strobe signals of all IP modules are accessible via a 4 pin jumper block on the TVME201. DMA, 32 bit
access and 32 MHz operations are not supported.
For improved EMI protection, four HD50 SCSI-2 type connectors are mounted in the EMI front panel
of the TVME201 and provide access to all IP I/O lines. Status indicators for IP access, +5V and +/-12V
are provided in the front panel.
A set of 16-position rotary switches allows easy configuration of VME Short I/O and Memory
addresses. Interrupt routing from the IP slots to the VME IRQs can be done in two ways:
programmable by software or selection of predefined sets by a rotary switch.
The IP power lines are fuse protected by self healing fuses and RF filtered. The operating temperature
range is -40°C and +85°C.

3.1VME A16 Base Address
The VME A16 Base Address of the TVME201 is set by rotary switch S1 and S2.
Rotary switch S1 sets A[15:12] of the VME A16 Base Address.
Rotary switch S2 sets A[11:10] of the VME A16 Base Address.
Figure 3-2 : VME A16 Base Address
The default value for the VME A16 Base Address is 0x6000 (S1=6, S2=0).
The TVME201 requires an address space of 1 Kbytes within the VME A16 address space. Each of the
four IP slots occupies 256 bytes within this 1 Kbytes VME A16 address space.
The address space for each IP is divided into the following areas: IP I/O space, IP ID space and the IP
IRQ and Control Register.
The IP I/O space has a size of 128 bytes. The size of the IP ID space and the IP IRQ and Control
Register depends on the position of switch S3:
With S3 = “0” to “7”, the IP IRQ and Control Registers of the TVME201 are accessible, and the size of
the IP ID space is 64 bytes. The remaining 64 bytes are occupied by the IP IRQ and Control
Registers. If switch S3 = “8” to “F”, the IP IRQ and Control Registers of the TVME201 are not
accessible, and the corresponding address range is added to the IP ID space, resulting in a size of
128 bytes for the IP ID space with S3 = “8” to “F”. This configuration is necessary for IP modules that
require access to the ID Space above the ID PROM.
See figures below for more details.

3.2Interrupts
Each IndustryPack can generate interrupts on two interrupt request lines (INT0 and INT1). The
VMEbus offers seven interrupt request level. IRQ7 has the highest priority, IRQ1 has the lowest
priority.
IP interrupt requests can be mapped to any of the 7 VME interrupt request levels. Interrupt routing
from the IP slots to the VME IRQs can be done by selection of predefined sets with a rotary switch or
programmable by software if S3 is in the range of “0” to “7”.
For more information about fully programmable interrupt mapping please refer to chapter “IP IRQ and
Control Register”.
Rotary switch S3 can be used to select predefined sets of mapping of the eight IP interrupt requests
(two requests per IP slot) to the seven VME interrupt request levels. The mapping selected with S3 =
“0” to “7” is mirrored at S3 = “8” to “F”. The difference is that access to the IP IRQ and Control
Registers of the TVME201 is only possible in switch position S3 = “0” to “7”. See Chapter “IP IRQ and
Control Register” and Chapter “VME A16 Base Address” for more details.

3.3VME A24/A32 Memory Enable and Size
If VME memory space is not required, switch S4 to “0” (VME A24/A32 memory disabled).
Figure 3-4 : VME A24/A32 Memory Enable and Size
IndustryPack Memory is mapped into the VME A24 or VME A32 memory space.
In VME A24 memory space, the memory size can be configured from 32 Kbytes to 2 Mbytes memory
per IP slot.
In VME A32 memory space, the memory size is fixed 8 Mbytes per IP slot.
Rotary switch S4 is used to enable/disable VME A24/A32 memory and to select the required VME
memory size. Default setting of S4 is “0”, which signifies VME A24/A32 memory is disabled.
Positions “1” to “7” of S4 represent several memory spaces in VME A24, and with S4 = “F”, each IP
has an 8 Mbytes memory space in VME A32 address space.
The Memory Spaces for all IPs have the same size. If i.e. one IP requires 128 Kbytes of
memory, one IP requires 64 Kbytes of memory and 2 IP require no memory, then S4 must be
set to “3”, which selects a VME A24 memory size of 512 Kbytes, 128 Kbytes memory for each
IP.

The memory space of IndustryPacks is mapped in the VME A24 or VME A32 space.
The memory base address for VME A24 or VME A32 is both set with the switches S5 and S6.
Figure 3-5 : VME A24/A32 Base Address

TVME201 User Manual Issue1.1.1 Page 15 of 26
If memory space is located in VME A24, S5 represents A[23:20], and S6 represents A[19:16].
In VME A32, S5 represents [A31:28] and S6 represents A[27:24].
The memory base address of the TVME201 must be set on a boundary equal to the memory
size, as selected by S4! See figure below for details.
The default value for VME A24 base address is 0xD00000 (S5=D, S6=0).
The default value for VME A32 base address is 0xD0000000 (S5=D, S6=0).

4 IP IRQ and Control Register
If switch S3 is in the range of “0” to “7”, the TVME201 provides a set of two registers for each IP: The
IP IRQ Configuration Register and the IP Control Register.
Setting switch S3 to a value of “8” to “F” disables the IP IRQ Register and the IP Control Register. The
address range of the IP IRQ and Control Register from “VME A16 Base Address” + “IP Offset” + 0xC0
to 0xFF is then mapped to the ID Space of the corresponding IP module, enlarging the ID Space of
each IP module from 64 bytes to 128 bytes.
4.1IP IRQ Configuration Register
Switch S3 must be in the range of “0” to “7” to access the IP IRQ Configuration Register. The register
is divided in 2 equal parts, one for each interrupt. The bits[0, 4] are the LSBs, and the bits[2, 6] are the
MSBs of the programmed IRQ level.
