MUX-16/32 Expansion Unit
VibWire-101
System Expansion
The VibWire-101 can be operated as a single channel device or can be expanded for large scale applications using the MUX-16/32 expansion unit. The VibWire-1018 when expanded using the MUX-16/32 units supports up to 64 x 4 wire sensors or to 128 x 2 wire sensors.

The terminal port on the instrument enables any channel on the MUX-16/32 to be selected under User control. This feature of the system considerably speeds up sensor testing in the field since the User does not have to wait for a complete scan in order to activate a specified sensor. The results for the sensor scan are available immediately.
Lightning Protection

The MUX-32 expansion unit contains in-built gas discharge protection to prevent damage to the instrumentation from local lightning strikes. For the lightning protection the MUX-16/32 has to be connected to a good earth. A solid earth mounting tab is provided on the MUX-16/32 to connect the device to the system earth.

Introduction
The VibWire-101 is a sensor building block for the creation of vibrating wire sensor systems. The basic device is a single channel unit making it an ideal low cost solution when individual remote monitoring of discrete sensors is required, or, as as a building block when large channel count distributed applications are required.
The VibWire-101 works with any data logger or network interface that supports SDI-12 or RS-485 digital network. Industry standard commands are used to start a measurement and recover data.
Environmental Protection
All of the VibWire-101 family of products are supplied in fully encapsulated plastic enclosures making the complete ideal for operation in harsh environments, tunnels, man holes or remote stand-alone applications. The instrument is immersion proof and will still be operating long after more expensive competitive products have failed.

The VibWire-101 and Q-LOG Software
The free version of the Q-LOG software supports up to 10 x VibWire-101 instruments onto a single digital network. The ViBWire-101 instruments running into this version of the software can be those expanded expanded using the multiplexer unit.
Data Values
The VibWire-101 can supply output values in Hz, Digits (Hz2), or SI Units. The temperature sensor output can be in units of Deg C or mV.

Terminal Port
Any modern terminal program such as the Microsoft Hyper-terminal or Token-7 that supports VT100 emulation can be used to access the VibWire-101 menu system. All of the sensor configuration parameters can be set using the terminal port.
