Megabyte, 1048576 bytes

Mbps
Megabits per second

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.
 ms
Millisecond, 10

s
 msb
most significant bit (within a byte)
 MSB
Most Significant Byte (within a multi-byte word)
 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.)
 PCB
Printed Circuit Board
