DATABASE MODE
NOTE: Because an IMCPM03 module in database mode is respon-
sible for collecting all exception reports in a PCU, there are some
important considerations for its use. No more than one IMCPM03
module operating in the database mode can operate on the Control-
way or module bus at the same time. The IMCPM03 module cannot
coexist with loop interface hardware when operating in the database
mode. The IMCPM03 module cannot be used in the same PCU as
an NPM, SBM or BIM module.
When the IMCPM03 module is functioning in the database
mode, the IMCPM03 scans all modules of the PCU for excep-
tion reports to update its import database. The IMCPM03 then
forwards each updated exception report to the work station or
console. The IMCPM03 also scans its export database for
exception reports that need to be sent to any other modules of
the PCU. All commands supported by the IMCPM03 in the
SPM/CPM02 mode are valid when the IMCPM03 is operating in
the database mode. Refer to Table
for the dipswitch assign-
ments.
NOTE: Since factory settings may not match default settings, it is
important to check all dipswitch settings before putting the module
into operation.
PREPARING THE MODULE MOUNTING UNIT
This section explains how to connect the Controlway to two
MMU backplanes. Refer to Figure
for the location of the
Controlway cable.
Verify the Controlway cable installation as follows:
1. Verify connection of one end of the twisted 3-wire to the
second column of two tabs on the lower left of the MMU back-
plane.
2. Verify connection of the other end of the cable to the first
column of two tabs on the lower left of the next MMU back-
plane.
NOTE: Because of high-speed transaction constraints, install a
maximum of eight related (Controlways linked by cable) MMU back-
planes within one cabinet. Do not cable link Controlways in separate
cabinets. The connecting three-wire lengths between MMU back-
planes should be minimized to prevent crosstalk and interference.
