Modbus 
A widely used control and automation communications protocol, often used in SCADA systems. 
 
Monolithic sensors 
Also called IC (Integrated Circuit) sensors. Sensors that are constructed on a single piece of silicon using integrated 
circuit fabrication techniques. Available sensors include those for measuring temperature (see 
Temperature – 
AD590 Series IC Sensors (P319)), pressure, acceleration and concentration of various compounds in gases and 
liquids.

  multidrop 
In communications, a multidrop configuration allows multiple devices to be connected in parallel by means of a 
single twisted-pair cable. This requires that each device switch off (tri-state) its transmitter when it is not actively 
transmitting. 
  multiplexer  
A "many-in, one-out" switching network that allows many input signals to time-share one analog input circuit. It 
sequentially routes multiple channels to a single signal processing system. 
  NAT 
Network Address Translation. A system used by TCP/IP routers to allow a small number of public IP addresses to 
be shared by many different devices on a private network. 
  Noise 
Unwanted voltage or current (generally with an AC component) superimposed on the wanted signal.  
 
NTP 
Network Time Protocol. A means of synchronising the DT80 system time to a time server on the Internet. 
  null-modem cable 
A communications cable for connecting two DTE devices together (for example, a PC to another PC, or a DT80 to a 
PC). Also known as a crossover cable. 
  Nybble 
Half a byte (four bits) 
  parse 
To identify components of a command string 
  PC 
A personal computer of the IBM or IBM-compatible type. (Although the Macintosh is technically a PC, it is not 
referred to as such.)
