Overview

1.2 Technical Data

1.2.1 Overview

The VME-ASIO16 is an input/output board for asynchronous serial data
transfer via 16 channels. Each channel can be operated as a RS-232
interface or as a 20 mA current loop. The operation mode can be
selected for each channel separately by jumpers. All signal and
supply lines are fed via the P2 connector.

The current loop interfaces are provided with electrical isolation
via optocouplers. For operation as current loop interfaces ±12 V
power can be supplied either externally via P2 or internally via the
VMEbus. The current sources for transmission and reception signals
are located on the board (active current source). At operation as
RS-232C interface the data lines and handshakes are available even
in the base version.

An interrupt logic with priority control generates a common inter­rupt on the VMEbus for each two channels. The interrupt level is
selectable from 1 to 7 by jumpers. An interrupt is also generated at
a line break of the 20 mA current loop.

Alternatively (Add-on-Board) the board can be equipped with up to 12
channels of RS-422 (optoisolated) and 4 channels of RS-232.
The channel handling is performed by up to 8 DUART 68681, depending
on the equipment of the board.

1.2.2 Real-time Software

Driver packages for the VME-ASIO16 are available for operating
systems such as VxWorks, OS-9 and others.

1.3 Address Selection on the VME-ASIO16

The setting of the base board address ensues via jumpers of the
jumperfields BR1 and BR2. The base address can be selected over the
whole address range of 16 Mbytes in steps of 256 bytes.

Additionally it is possible to use the VME addressing mode ’SHORT ­I/O’. At this addressing the address lines A16 to A23 are ignored
and the base address of the VME-ASIO16 is placed into the ’SHORT
I/O’ address range (64 kbytes) of the VMEbus system.

The peripheral components DUART 68681 are provided with an 8 bits
wide data bus and with 4 address lines (A1 to A4). The addresses A5
to A7 select the desired DUART on the VME-ASIO16.

only a part of the DUARTs will be inserted: starting at the end with
DUART no. 8, e.g. when the board is equipped with 4 channels, the
DUARTs 8 and 7 will be inserted, for 10 channels the DUARTs 8, 7, 6,
5 and 4 will be inserted.

Jumpers Configuration

Only the configurations listed above are meaningful for the addres­sing of the board. The evaluation of the address modifiers AM3 and
AM5 cannot be changed by the user. It is fixed to ’H’ by the hardwa­re.
For the evaluation of the address modifiers also the signal ’LWORD’
is used. It is fixed to ’H’, because the VME-ASIO16 is not addressed
for 32 bit ’LONGWORD’.

If the addressing mode ’SHORT SUPERV. I/O ACCESS’ or ’SHORT NONPRIV.
I/O ACCESS’ is selected, the jumperfield BR2, which fixes the ad­dresses A16-A23, is not evaluated when the board is addressed. The
setting of the base address in the 16 Mbyte address range is inef­fectual.

As an additional option for the addressing of the VME-ASIO16 the
address modifier AM2 can be set to ’don’t care’ by inserting the
corresponding jumper. As a consequence a ’SUPERVISORY’ access as
well as a ’NONPRIVILEGED’ access will address the board.

ATTENTION ! The address modifier configuration $3F or $3B respec-

tively, corresponding to ’STANDARD SUPERV. ASCENDING
ACCESS’ or ’STANDARD NON-PRIV. ASCENDING ACCESS’
respectively, are possible, but not meaningful becau­se the VME-ASIO16 does not support these addressing
modes.

AM signals as follows in the table.

1.4.2.2 Base Address Decoding via Jumpers BR1 and BR2

The setting of the base board address ensues via jumpers at the
jumperfields BR1 and BR2. The base address can be selected in steps
of 256 bytes over the whole address range of 16 Mbytes. Furthermore,
it is possible to use the VME addressing ’SHORT I/O’. At this ad­dressing the address lines A16 to A23 are ignored and the base
address of the VME-ASIO16 is placed into the ’SHORT I/O’ address
range (64 kbytes) of the VMEbus system.

The address decoder logic generates a ’CARDSELECT’ signal, which
serves as an enable signal for the decoder logic of the DUARTs.

The interrupt level is set via the jumperfield BR4. The level is set
by inserting the corresponding jumper. Factory-set is an inserted
interrupt ’IRQ4’.

It is not allowed to insert more than one interrupt level

1.4.3 Jumperfields of the Serial Interfaces

1.4.3.1 Feeding of the Power Supply

Near to VMEbus P1 connector pin 32 there are the jumpers BR5 to BR8,
which connect the power supplies of the VMEbus to the TTY interface.

If these jumpers are removed, the corresponding voltage must be
supplied via the P2 connector of the VME-ASIO16.
To guarantee an electrical isolation in the TTY mode, the voltages
+12V, -12V and GND, must be fed by an external power supply (the pin
assignment can be obtained from the appendix).
To this the pins of the handshake signals of the channels 13 to 16
on P2 are used, which are not necessary for TTY operation. Connec­tion is performed by means of wrap wires from the pins ’2’ of the
jumpers BR5 to BR8 to jumperfields BR43 and BR44, pins 2 and 8, and
to jumperfields BR53 and BR54, pins 3 and 6 (see fig. 1.4.2).

VME-ASIO16 Rev. 1.7 23

Jumpers Configuration

The position of the jumpers for the handshake signals (DTRx, CTSx)
can remain unchanged, because the TTY interfaces run without ’hard­ware handshake’. Besides, the function of the handshake signals can
be varied via the jumpers BR33 to BR40 (see also chapter 1.4.3.3).

A survey of the combination of the several jumpers is
displayed in figure 1.5.1 ’Circuitry of the Serial Interfaces’

For a better orientation jumpers of different colours are factory­inserted for data and handshake signals.

Jumpers Configuration

1.4.3.3 Control Signals of the Serial Interfaces

The jumpers BR33 to BR40 cover the lines DTR1 to DTR16 with the
control lines RTS or DTR, if the jumpers BR43 to BR50 are set corre­spondingly. A switch-over between these signals ensues only in
combination with the firmware!

A survey of the combination of the several jumpers is
displayed in figure 1.5.1 ’Circuitry of the Serial Interfaces’

The jumpers assignment to the channels is as follows:

channel jumper signals at P2

1+2 BR40 DTR1, DTR2

3+4 BR39 DTR3, DTR4

5+6 BR38 DTR5, DTR6

7+8 BR37 DTR7, DTR8

9+10 BR36 DTR9, DTR10

11+12 BR35 DTR11, DTR12

13+14 BR34 DTR13, DTR14

15+16 BR33 DTR15, DTR16

Table 1.4.5: Channel Assignment to the Jumpers BR33 to BR40

The jumpers set the ports OP4 and OP5, or OP0 and OP1 respectively,
of the DUART68681 (via drivers) to the local signal lines ’RTS/DTR’.
These lines are connected to the I/O connector P2 via the jumpers
BR43 to BR50 and BR53 to BR56.

Following functions are assigned to the ports by firmware:

port signal remark

OP0, OP1 RTS ’Request To Send’:

announcement of a transmit
process
(e.g. for modem operation)

OP4, OP5 DTR ’Data Terminate Ready’:

default handshake control for

Serial Interfaces

1.5 Serial Interfaces

1.5.1 Circuitry of the Serial Interfaces

One DUART68681 operates two serial interfaces at a time on the
ASIO16. The interfaces can be operated as RS-232 interfaces or as
TTY interfaces corresponding to the jumpers position.
For reduced version of the VME-ASIO16 with less than 16 channels
only a part of the DUARTs will be inserted, beginning at the end
with DUART no. 8, e.g. at a 4 channel insertion the DUARTs 8 and 7
will be inserted, at 10 channels the DUARTs 8, 7, 6, 5 and 4 will be
inserted.

The displayed jumper positions correspond to the factory-setting of the board (RS-232
operation, DTR handshake).
The power supplies of the electrically isolated components (+12V process, -12V
process) can be supplied externally or be connected to the local (VMEbus) power
supplies.

Fig. 1.5.1: Circuitry of the Serial Interfaces (Example: Channel 1)

VME-ASIO16 Rev. 1.7 29

Serial Interfaces

1.5.2 The RS-232 Interface

The interface controller DUART 68681 processes tranmsit and receive
signals of TTL level. The interface to V24 or RS-232-C respectively,
is realized by integrated level transformers MC1488 (transmitter)
and MC1489 (receiver). Both components are located on the board
below the corresponding DUART.

1.5.3 The TTY Interface

The current loop interface is located behind the V.24 voltage inter­face, i.e. the V.24 level is transformed into 20 mA current level to
be transmitted. Current loop receive signals are transformed vice
versa. The current loop signals are electrically isolated from the
VMEbus to fulfill the requirements of process automation. (When
’using’ the electrical isolation the power supply of the TTY inter­face must be supplied externally.)

The current loop transmitter consists of a switched constant current
source. Beside a constant current source the receiver contains a
Schmitt-Trigger for the signal preparation and for noise suppres­sion.

The VME-ASIO16 current loop interface is designated as "non isola­ted", because all necessary current sources are located on the
board; thus the process section must not be equipped with current
sources!

VME-ASIO16 Rev. 1.730

Interrupt Processing

1.6 Interrupt Processing

A circuitry on the VME-ASIO16 connects the interrupt requests of all
DUARTs with a common IRQ and coordinates the arbitration. At this,
priorities are assigned to the single DUARTs, so that simultaneously
occurring interrupts are processed with respect to their priority.

Each interrupt request of DUARTs is indicated by LEDs (green). So at
a failure the user can recognize, at which IRQ no service ensues via
the VMEbus.

The VMEbus interrupt level can be selected via jumper BR4. Factory­set at the VME-ASIO16 is ’IRQ4’.

The LED ’IRQ’ at the front panel indicates, that at least one of the
interrupt outputs of the DUARTs is active.

The LEDs 1/2, 3/4, 5/6, and so on indicate the active condition of
the interrupt signal of the single DUARTs 68681.

2. RTOS-UH Software Support

2.1 Survey Channel Structure

For PEARL/RTOS-UH users an integrated driver with complete interrupt
support is contained in the extent of delivery of the VME-ASIO16
(EPROM resident). Parameters such as baudrate, bits/character,
parity among other things, can be configured for each channel in
clear.

To each serial ASIO16 channel a data station designation and a RTOS­UH-LDN are assigned. Basically a serial channel consists of an input
and an output channel, furthermore a parameter channel is available.
In the following table the data station designations for two com­pletely equipped VME-ASIO16 in one system are listed. Please consi­der, that the ASIO software channel 1 is fed to the hardware inter­face of the DUART no. 8 of the first board, and the ASIO software
channel 17 is fed to the hardware interface of the DUART no. 8 of
the second board.

Table 2.1.1: Data Station Designation Survey

For future implementations of the ASIO driver under PEARL/RTOS-UH
the parameter channel Px. should not be used any more, but instead
of this it should be represented as Ix.PARA (input channel with file
name), however the set of parameters of the channel Ix.PARA remains
identcal to the parameter channel Px described in the following.

In the PEARL SYSTEM section e.g. the statement

para_channel_x: Px.PARA <->; can subsequently easily be changed to
para_channel_x: Ix.PARA <->;

For the data channels following format is valid:

input_channel : Ix.input
output_channel: Ox.output

3.2 ASIO16 Adaptor (VME-ASIO-ADAPT)

3.2.1 General

The VME-ASIO16 P2 adaptor offers 16 times 14 pole connector plugs
for the direct connection of the serial interfaces to a flat cable.
Moreover, on the adaptor there are screw terminals available for the
connection of external power supplies.

To avoid overvoltages on the TXD line, pin 2 of the 14 pole connec­tor plug is connected with the +12 V potential via a 24 V Z-diode.

The connector plugs are covered with the signals of the RS-232
interface or of the TTY interface via the jumpers BR1 to BR16.

The externally supplied voltages are fed via the jumpers BR21 to
BR26 to the P2 connector of the ASIO16.

Attention: If the power supplies are fed externally via the ASIO

adaptor, the ASIO16 must be configured correspondingly
(see chapter ’Feeding of the Power Supply’)!

If no external power supplies are connected, the VMEbus voltages
+12V, -12V and GND must be connected with the corresponding termi­nals! The jumpers BR21 and BR24 to BR26 must remain not inserted.
(The jumpers BR22 and BR23 remain not inserted only, if the ASIO-422
add-on is not inserted.)

If the interfaces are supplied by the local ASIO16 VMEbus supply,
the jumpers must not be inserted (different P2 connector pin as­signment)!

An exception is the GND jumpers BR22 and BR23, which must always
be inserted, if the ASIO-422 add-on is inserted. This is necessary

Add-On

3.3 Add-On ’ASIO-422’

3.3.1 General

The RS-422 add-on, available as an option, has to be inserted into
the jumperfields BR43 to BR50, BR53 to BR56 and BR5 to BR8. If the
add-on shall be inserted, the components of the TTY interfaces must
not be inserted, because this area is required for the add-on.

The add-on offers a maximum of 12 interfaces, electrically isolated
from the VMEbus and from the local components, with a simultaneous
possibility of using 4 RS-232 interfaces in the ’XON/XOFF-only’
operation (channel 13 to 16 - on the base board). Partial insertion
of 4 (channel 9 to 12) or 8 (channel 5 to 12) RS-422 interfaces,
respectively, is possible.

The electrical isolation of the RS-422 interfaces ensues by means of
a DC/DC converter on the add-on. The feeding of the power supply for
the add-on (including DC/DC converter) can ensue from the ASIO16
(VMEbus supply) or externally via the ASIO16 P2 connector.
When using the ASIO P2 adaptor it must be taken care that the add-on
reference potential (GND) has to be fed via the adaptor jumpers BR22
and BR23 to the 14 pole connector plug. These jumpers must also be
inserted if no external power supply is fed to the board!

3.3.3 Jumpers of the ASIO422 Add-Ons

3.3.3.1 Selection of the Power Supply via the Jumpers J1

to J3

If an external power supply of the ASIO422 add-ons is desired, the
jumpers J1 to J3 must be inserted.

Attention:

In this case the connectors P1 to P4 must not be inserted on the
add-ons.(see fig.3.3.1)!
