Multiplexer
The ProMUX-3 multiplexer features three inputs and one RS232 output. The ProMUX-4 and -8 can have either 4 or 8 inputs and one RS232 or RS422 output. And the ProMUX-RF has one input and 2-way wireless transmission to a receiver with RS232 output. Created for multiplexing and sending SPC data to a PC, the ProMUX-3 and ProMUX-RF work with or without standard digital readouts. The ProMUX-3 uses a plug-in 110/220V ac power supply and internal rechargeable batteries. The ProMUX-4 and -8 operate with user supplied 10-24V dc and can be cascaded to provide up to 128 channels of input for large-scale data collection or multiple outputs to a PLC or controller.

Transformers
Three families of octal transformer modules are designed compatible with PMC Sierra's 4- and 8- channel ICs for T1/E1/J1 applications. Octals come in standard 40-pin, 32-pin miniature space-saving, and 40-pin with integrated surge protection packages. They also provide an isolation voltage of 1,500V rms, and support 4 transmit-and-receive channels. These quad-port devices have eight transformers and an operating temperature of -40 to 85C. Each part number is specifically designed to match manufacturer chipsets.

Frame grabber
The Bandit-II MV is a monochrome frame grabber with integrated VGA display.
This unit has a dedicated acquisition control that works with fixed or variable-scan cameras. Other features include external clock input, a two-pulse Schnitt trigger input, a timer for strobe and exposure control, optically isolated general purpose I/O, and a PC-independent RS232 port. This system captures at sampling rates of up to 40 MHz for monochrome or 30 MHz for RGB cameras. Each input channel has a bypassable low-pass filter as well as independent gain and offset controls. Applications include industrial vision automation, semiconductor, and industrial inspection.

C-compiler
The XPP™ vectorizing C-compiler allows a developer to create reconfigurable ASICs using C language source code. It is capable of running in multiple, parallel instances on the PACT core. Acting as a preprocessor, the XPP extracts and creates parallelized XPP code from existing C programs and allows developers to reuse their existing code base on the XPP core. This compiler boasts increased speed, flexibility, and reduced power consumption. It is designed for development on a hybrid RISC/XPP or DSP/XPP system but it can also be used as a stand-alone compiler for XPP cores.

Inverter
The P44 series dc-ac inverter is powered by 2 to 4 cold cathode fluorescent lamps. Designed for backlighting of flat panel and other LCD modules, the inverter provides 15W output power, external control, and pulse width modulation dimming. The PC-mountable inverter is vacuum encapsulated for environmental resistance. Module dimensions are 1 × 2.57 × 0.69 inches. Applications include flat panel desktop monitors, medical diagnostic monitoring equipment, and instrumentation in industrial and avionics.
