SPECIFICATIONS
The IO100VXI and IO50VXI Digital Input/Output modules were developed for use in process control, microprocessor cycle emulation, bus cycle
emulation, process simulation and functional board or circuit test applications. All modules are single slot, C-size VXI modules, with the IO100VXI
providing up to 128 channels of digital I/O and the IO50VXI providing up
to 64 channels of digital I/O. Each group of 8 channels may be software
configured as either input or output. Tristate control of outputs allow for
emulation of bidirectional data and control buses. Four 50-pin IDC connectors are provided on the IO100VXI front panel; two on the IO50VXI.
Each I/O connector provides (32) I/O channels, (4) I/O handshake strobes,
and (4) tristate control/output enable inputs.
Logic Families:
All modules utilize a high level, SCPI compatible command set for setup
and control of I/O channels. Thy also support VME dual-ported RAM
and registers. I/O pins may be programmed by sending high-level commands or with direct, high speed VME read/writes, the same as might be
used for register-based instruments. Using this combination of programming formats results in the best of both worlds, high functionality and high
speed.

Memory emulation and block I/O modes allow autonomous operation
from the local microprocessor. Data fields may be programmed from 1 bit
to 32 bits wide. Multiple data fields may be defined, allowing I/O pins to
be grouped together based on function. Double latching the outputs allows
all output channels to transition at the same time regardless of field size or
the number of fields defined. Latching the inputs allows a full 128-bit wide
read with a single command (64 channels for the IO50VXI). Utilizing the
VXITTLTRG lines, modules may be linked together for even wider I/O
channel groups.
The IO130VXI and IO53VXI use 32 output channels to drive 30 optically
isolated solid state relays. This allows the module to control high voltage
applications up to 100 volts. Switched voltages can be either user supplied
or selected from +5, ± 12 , and ± 24 volts available from the VXI backplane.
Both modules use a mezzanine board to provide the switched high voltage
outputs. Other input and output logic formats can be supported via user
supplied mezzanine boards.
The IO54 and IO140 modules are the latest additions to the IO50 / IO100
family. The IO54 provides 32 Differential TTL I/O channels, each provided with a switchable 100 ohm termination. The IO140 provides 32
differential I/O channels with switchable 100 ohm terminations, plus 64
TTL I/O channels. Differential I/O channels meet RS-422-A standard.
Both modules support external I/O handshaking. IO140 TTL channels are
the same as the IO100 TTL channels described above.
