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.

Address Covering
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.

Table 1.3.1: Address Model of the VME-ASIO16
For reduced versions of the VME-ASIO16 with less than 16 channels
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.
The register model and the meaning of the single bits can be obtained from the data sheet of the DUART 68681 in the appendix.
