The OPTO32D board has 32 optically-coupled digital I/O channels consisting of 8 outputs and 24 inputs. Each channel is electrically isolated (1000 Volts) from the host processor board. Change-of-State Interrupts allow for an interrupt to the PMC host to be generated from any level change on any input. Built-in-self-test, selectable debounce times, input pulse counter, and I/O voltages to 50 Volts makes for a versatile digital interface board.

The PMC-DIO24 is a simple 25-bit discrete I/O interface board. The host side connection is PCI based and the external I/O interface is variable (see below). The external interface includes 24 signals that can be arbitrarily programmed as either input or output and one signal that is input only. The 24 programmable signals are divided into three groups of eight pins each; Port A, Port B and Port C. Ports A and B are each programmable as all inputs or all outputs. The Port C signals are individually programmable. Although the DIO24 provides extensive flexibility to accommodate many user applications, custom interfaces exist which may not conform to current DIO24 interface options. General Standards Corporation has worked with many customers to provide customized versions of the DIO24 and other GSC products. Please consult our sales department with your specifications to inquire about a custom application.

The PMC-SIO4AR is a four channel full-duplex RS-422/485 serial board with Rear I/O. Each channel can operate up to 10 Mbits/ s. Optional 32 Kbyte FIFO buffer for both transmit and receive (256 Kbytes Total FIFOs) data on each channel provides for a smooth and efficient interface between the serial interfaces and the PMC host computer. The board is based on the Zilog© Z16C30© high speed Integrated Universal Serial Controller (USC) which sup-ports Asynchronous, Isochronous, Bisync, Monosync, HDLC, SDLC, External Sync and Nine-Bit protocols. The USC chip provides full duplex operation with baud rate generators, digital phase-locked loop for clock recovery and a full duplex DMA interface.

VME-SIO4A is a four channel RS422/RS485 or RS232 serial board. Each channel can operate up to the maximum 10 Mbits/ sec. An optional FIFO buffer (up to 32 Kbytes) for both transmit and receive data on each channel provides for a smooth and efficient interface between the serial interfaces and the VME host processor. The board is based on the Zilogª Z16C30 high speed Integrated Universal Serial Controller (USC) which supports Asynchronous, Isochronous, Bisync, HDLC, SDLC and Nine-Bit protocols. The USC chip provides full duplex operation with baud rate generators, digital phase-locked loop for clock recovery.

The PMC-SIO4AR-SYNC is a four channel full-duplex RS-422/485 serial board with Rear I/O. Each channel can operate up to 8 Mbits/sec.

The card features a simple 3 signal interface utilizing a clock, data and an enable.

The CPCI-SIO4ARHM and its transition module make a four channel full-duplex RS-422/485 serial board set. Each serial channel of the CPCI-SIO4ARHM can operate up to 10 Mbits/s in synchronous mode. Optional 32 Kbyte FIFO buffer for both transmit and receive (256 Kbytes Total FIFOs) data on each channel provides for a smooth and efficient interface between the serial interfaces and the host computer. The board is based on the Zilog Z16C30 high speed Integrated Universal Serial Controller (USC) which supports Asynchronous, Isochronous, Bisync, Monosync, HDLC, SDLC, External Sync and Nine-Bit protocols. The USC chip provides full duplex operation with baud rate generators, digital phase-locked loop for clock recovery and a full duplex DMA interface. One of the rear transition module is required and is priced separately. The module is available with RS-422/485 or RS-232 transceivers. Contact General Standards for pricing and availability. The CPCI-SIO4ARHM also has a PMC host site to allow customers to create more compact system solutions. Customers can mount any PMC board, including General Standard's PMC-SIO4A board. The CPCI-SIO4ARHM and the PMC-SIO4A combination will provide eight serial ports in a single CPCI slot.
