Hardware Input Signal Configuration Switches:
Four sets of Input Configuration Switches are provided for each of the four
channels (Figure 3... -11). Through the use of these switches, various types
of signals can be directly fed into the OMP-MODL eliminating the need for
User supplied external precision dividers, shunts and other circuitry.
Although for most applications, an in-depth understanding of the function of
these switches is not required, a simplified schematic of the input section of
the MLIM-1 is provided in Figure 3... -12. As can be seen in this schematic,
different combinations of the switches interject voltage dividers and shunts
into the input stage of the Interface Module.
The following reference chart provides the necessary information for
configuration of the input switches. The switch settings are read by the
OMP-MODL during a query of the hardware configuration (from within
HyperNet) so the User is not burdened with keeping notes of the current
Module configuration. Improper setting of the switches will result in a `Bad
Configuration’ message on the LCD upon power-up of the OMP-MODL. In
the event that this message displays, check the switch settings per Table 3...
-4 and correct the conflict.
