2.6.2 4XTMF, 4XLMF and 4XZMF Option Modules
MS-4: The 4XLMF LED Interface Module can only be plugged into connectors J3 and J5 on the
MS-4 main circuit board. The 4XTMF and 4XZMF modules can be plugged into connectors J3
and J5 or J4 and J6 on the MS-4 main circuit board. A combination of any two of the three
modules can be installed.
MS-2: Only the 4XTMF module can be plugged into connectors J3 & J5 on the MS-2 main circuit
board. (No other option modules can be installed on the MS-2).
