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

PositionSymbolMeaning
L SRS-232
DRS-485
n 1RJ-45 (Modicon compatible pinout)
24-wire (5 position screw terminal)
32-wire (3 position screw terminal)
pp 01Modbus RTU, 9600 bps
02Modbus ASCII, 9600 bps
03Modbus RTU, 19200 bps
04Modbus ASCII, 19200 bps, protocol custom for G3 I/O bus
05PLogic/PNIM/RNIM, 9600 bps
06KYZ counter, Modbus RTU, 9600 bps
07KYZ counter, Modbus RTU, 19200 bps
08Modbus 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:
