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 inter-
rupt 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.
