INSTALLATION
Remove all system power before installation,
first battery and then AC. (To power up, connect
the AC first, then the battery.)
Unpack the MKB-5/-5C. Inspect the module for such
things as integrated circuits (ICs) not firmly seated in
their sockets, bent IC pins, connectors not properly
installed, dirt, and packing material on the board.
NOTE:
The MKB-5/-5C is supplied with the keyboard annun-
ciator mounted to the hinged panel, but with black filler
plates installed to the right and left to accommodate a
telephone and microphone, if used. To install the
telephone module (TMM-1) or microphone module
(MMM-1) on the MKB-5/-5C, follow the installation
instructions which accompany those modules (P/N
315-092098 and P/N 315-092099, respectively). To
install the TMM-1 module when using an MMB-3, it is
necessary to first remove the ANN-3 board on the
back of the MKB-5. After the TMM-1 is mounted, the
ANN-3 can then be replaced.
Setting the Network Address
Set the Network Address for the MKB-5/-5C using the
three ten-position rotary switches (S1, S2 and S3)
located on the back of the keyboard/display panel, as
shown in Figure 2. For example, to set the switches to
address 248: set S1 to 2, set S2 to 4, and set S3 to 8.
The possible addresses for this module are 248, 249,
250, and 251.
NOTE: There is no need to set supervision on the
MKB-5/-5C because it is, by default, always
supervised. No unsupervised annunciators
(MKB-1/-2/-3/-4) are allowed at the same
address as an MKB-5/-5C. Unsupervised
applications require the use of the MKB-1/
-2/-3/-4 and they must all be set to the same
address.

Mounting the MKB-5/-5C
(Refer to Figure 3)
1. Install four screws in the first group of four tapped
holes in the right flange. Leave a
between the head of the screw and the flange.
Slide the slots of the MKB-5/-5C panel hinge
under the head of the screws and tighten.
2. If the panel locking fastener is not aligned with the
hole located on the left flange, loosen the screws
and adjust accordingly. Retighten the screws.

Wiring
(Refer to Figures 4, 5 and 6)
1. Pull all field wiring into the backbox and dress the
wiring to the approximate location to which it will go.
2. Remove the connector plugs from J8. Attach the
wiring to the connector plugs in positions 1 and 2 for
Style 4 and positions 1, 2, 3 and 4 for Style 7. Always
connect position 5 to Chassis GND (Earth GND).
3. Remove the connector plugs from J12. Attach the
field wiring to the connector plugs, making sure
that position 1 on J12 is for +24VDC and position
2 on J12 is for -24VDC return.
4. If needed, J11 is the connector for a parallel
printer and J10 is the connector for a serial printer.
The serial connection can be supervised; the
parallel connection is supervised by default. Note
that only one printer, either parallel or serial, may
be connected to the system.
