NOTES The H/L column represents the “HI” and “LO” pins for the 4-wire signal.
The “BPL” references are lines available on the EX1200 mainframe backplane that connect the
plug-in module to the on-board DMM (if installed). For more information on these lines, refer to
the EX1200 Series User’s Manual.
