The XVME-240 is an 80-channel, TTL-level, VMEbus-compatible I/O module. Sixty-four of these channels are arranged to form eight (byte-wide) bidirectional I/O ports. Each port can be separately programmed for either input or output by simply setting or clearing a single corresponding bit in the port direction register. Each channel also has one edge selectable interrupt input line and one flag output.

• 64 channels (8 ports) of bidirectional TTL I/O
• 8 channels of edge-selectable interrupt inputs with programmable mask
• 8 channels of flag outputs
• High density, low cost-per-channel

The XVME-230 Intelligent Counter Module is a VMEbus-compatible intelligent I/O module which provides a variety of high-performance, high-level counting functions. The module's architecture features the Xycom Automation intelligent I/O kernel which can significantly enhance system performance by itself handling many time-consuming functions that would otherwise be performed by the host processor. This on-board intelligence also gives the XVME-230 exceptional measurement and stepper motor control performance.

The XVME-212 Module provides 32 optically-isolated digital input channels. This module features programmable scanner circuitry that can detect a change-of-state on any of the 32 input channels. The XVME-212 eliminates the need for the host processor to constantly poll the digital I/O to obtain signal transition data. Upon an input transition, the module can notify the host processor by generating a VMEbus interrupt.

• 32 optically-isolated digital input channels
• Programmable scanner
• VMEbus interrupt capability
• Input debouncing circuitry
• Reverse bias protection
• Isolated 12-volt supply

The XVME-203 is a single-high (3U), VMEbus-compatible board, using two AM9513A timer/counter devices to provide a total of ten 16-bit counting channels. The timer/counter devices are fully programmable and capable of counting at a rate of up to 5 MHz. In conjunction with the timer/counter devices, the XVME-203 employs an AM9519A Universal Interrupt Controller to provide a complete interrupt structure via eight interrupt channels. This interrupt structure allows for the selection of either a fixed interrupt vector for all eight channels or a separate vector for each individual channel.

• Single Eurocard (3U) size
• Ten 16-bit counting channels
• Counting rates up to 5 mHz
• Buffered inputs and outputs
• On-board Quadrature Detection circuitry
• VMEbus interrupts

The XVME-202 PAMUX Controller Module is a single-high (3U) VMEbus-compatible interface to the PAMUX 4, 5, and 6 remote I/O products available from OPTO 22.

• Directly compatible with the OPTO 22 line of PAMUX 4, 5, and 6 I/O systems
• 116 PAMUX units can be addressed from one XVME-202 module, providing up to 512 individual control points
• Cable length between the XVME-202 and the PAMUX units can be up to 500 feet
