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. 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.
