Caution
If you are using a PC-LPM-16/PnP, do not use 5B Series analog output modules
in the last two slots of the 5B backplane connected to the connector because the
±12 VDC supply is routed to those slots. Doing so can damage the modules and
the PC-LPM-16/PnP.
Figures 7-3 through 7-7 show the pin assignments for each connector on
the SC-2055.
