MSI (Sometimes referred to as Modified Plessey Code)
MSI is a discretecode capable of encoding variableĆlength messages (up to 14
characters) from the set of numerics. Each character has four bars and four
spaces. When read from left to right, each barĆspace pair represents one bit:
a narrow barĂ/Ăwide space combination represents a zero, a wide barĂ/Ănarrow
space combination represents a one. Characters are comprised of four bits
each, with the MSB (most significant bit) first.
Despite the requirement ofone check digit,the symbology requireshigh quality
printing and is not secure. Default = Off.
