To enter data in the system’s database, the Write Protect switch must be in the OFF position. In the
ON position, the database cannot be modified. Thus, placing the switch in the ON position
eliminates the potential for remote database modification. If remote data entry is not desired, after
all installation and database entries are complete place the switch in the ON position.
When new gateway Modules and/or terminals are connected to a LAN, they will automatically
attempt to register with an MFIM. With the Registration switch (switch 3) in the ON position, the
system will recognize and respond to the registration request. With the switch in the OFF position,
the system will not respond to the request. During initial installation, the switch should be placed in
the ON position to permit the system to recognize and respond to registration requests. If it is
desired to deny future registrations, the switch should be placed in the OFF position. This is useful
when multiple systems may be connected to the same LAN. For details on gateway Module and
terminal registration refer to the
iPECS Admin & Program Manual
.
The system database is initialized based on switch position 4. In the ON position the system will
load default values in the system database when power is applied to the MFIM or the Reset button
is pressed. Note if the system looses power for any reason with the switch in the ON position, the
database will be initialized. Place the switch in the ON position then, after completing the system
wiring and prior to any database entries, place the switch in the OFF position. For a description of
the initialization process refer to the
iPECS Admin & Program Manual
.
Wiring Connectors
Before wiring any of the Modules, first connect the “ ” screw on the back of the Module to a
known ground, refer to section 4.5.1.4.
On the front of the MFIM are the “LAN 1” and “LAN2” RJ-45 type connectors. These connectors
should be wired to the appropriate LAN points as discussed in section 4.5.1.6 and 4.5.1.7.
¾
Wire “LAN 1” to a 10/100 Base-T switch, a POE8 can be used to connect to the LAN.
¾
For redundant processor operation, wire “LAN 2” of main and back-up MFIM.
¾
Tag or number wiring for maintenance.
The eight (8) RJ-45 connectors on the rear panel of the MFIMs are terminated for miscellaneous
functions. The connectors are wired as Figure 4.5.2-1 and Figure 4.5.2-2. Note the MFIM300 and
MFIM600 include terminations for additional relay contacts and connection for the external PFTU
box, GDK-100.
¾
Wire Miscellaneous function connectors as depicted in the sketches of Figure 4.5.2-1
and Figure 4.5.2-2. These connections are not available from the Main Cabinet back
plane.
