Mux/64 Measurement Computing Analog Multiplexer

Mux488/64 and Mux/64 are 64 single-ended or 32 differential signal analog multiplexers. They expand the input channel capacity of analog data acquisition systems and can provide front-end signal multiplexing for analog to digital (A/D) converters such as the IOtech ADC488. The multiplexers can be switched directly under program control or can be switched automatically through a programmable sequence of settings.

For application flexibility, the Mux488/64 and Mux/64 can be easily configured for the following switching capabilities:

• 64 single-ended inputs: One single-ended output
• 32 differential inputs: One differential output
• Two banks of 32 single-ended inputs: 2 single-ended
• Two banks of 16 single-ended inputs: 2 differential outputs
• Four banks of 16 single-ended inputs: 4 single-ended outputs
• Eight banks of 8 single-ended inputs: 8 single-ended outputs
• Four banks of 8 differential outputs: 4 differential outputs

A Mux system can be set up in one of several configurations: master/slave with RS-232C or IEE 488 interfacing. LPT port peripheral, plug-in card port peripheral or digital I/O port peripheral. A Mux488/64 can be set for master, slave, LPT port, digital I/O port or plug-in card port peripheral operation. It is a master unit that can be operated independently or as the control unit for up to fifteen slave Mux/64s. A Mux/64 can only be set for slave, LPT port, digital I/O port or plug-in card port peripheral operation. Mux/64 is not capable of master operation. Mux488/64 programs slave units through its digital control port, a parallel TTL interface. Digital control can be driven by a Mux488/64 acting as a master, any parallel Centronics port, or a digital I/O interface such as the IOtech Power488, the MetraByte PIO-12 or DAS-16 or the digital I/O port of the Data Translation DT2801.
