Control Interface Module, Continued

The CIMBase is equipped with several LEDs that relate useful

information regarding the operating status of different interfaces. These

LEDs are shown in figure 2-6 and described in table 2-3. The CIMBase

is also equipped with certain option switches, described below, that must

be set appropriately for proper operation. Before installation, verify that

all switches are set correctly. When replacing a CIMBase verify that the

switch settings on the new board match the switch settings on the board

being removed.

CIMBase LEDs and

Options

• I

C Bus Pull-Up Dip Switches – These switches are set to OFF

for a particular CIM I

C Bus when that bus is connected directly

to the internal I

C distribution on the PECM-DC. They are set to

ON otherwise. There is one set of two switches for I

C Bus A

and another set for I

C Bus B (as marked on the board). Both

switches for a particular bus must be set the same.

• CPLD Spare – These switches are not used in normal operation,

and are set to OFF.
