MST Cross Reference & Product Numbering

The new MST product part numbering scheme will allow the part number to "grow" as the board proceeds through the manufacturing process, and will simplify mainentance of the firmware, since a single piece of code could be used in six different MST products.

In the part number:

MSTL-npp

Position	Symbol	Meaning
L	S	RS-232
	D	RS-485
n	1	RJ-45 (Modicon compatible pinout)
	2	4-wire (5 position screw terminal)
	3	2-wire (3 position screw terminal)
pp	01	Modbus RTU, 9600 bps
	02	Modbus ASCII, 9600 bps
	03	Modbus RTU, 19200 bps
	04	Modbus ASCII, 19200 bps, protocol custom for G3 I/O bus
	05	PLogic/PNIM/RNIM, 9600 bps
	06	KYZ counter, Modbus RTU, 9600 bps
	07	KYZ counter, Modbus RTU, 19200 bps
	08	Modbus ASCII, 7 data bits, 9600 bps

The old MST- part numbers will continue to be unique, since their 3 digit codes all began with zero. Each of the old part numbers will also have a new part number:

Old number	New number	Description
