outputs and MID-16 general purpose
inputs. This gives a maximum of 8 MOD-16
boards and 8 MID-16 boards.
The MOI-7 subaddress map is as follows.
001-016 MOD-16/MID-16 #1
017-032 MOD-16/MID-16 #2
033-048 MOD-16/MID-16 #3
049-064 MOD-16/MID-16 #4
065-080 MOD-16/MID-16 #5
081-096 MOD-16/MID-16 #6
097-112 MOD-16/MID-16 #7
113-128 MOD-16/MID-16 #8
The MOI-7 has two status LEDs:
The TRANSMIT LED indicates that the
MOI-7 is sending information to the SMB-2.
During normal operation this LED flashes
periodically when the SMB-2 requests the
MOI-7’s status.
The TROUBLE LED only lights when the
MOI-7 cannot communicate with the
MXL-IQ. This is an indication that the
network connection between the MOI-7 and
SMB-2 is damaged.
MOD-16 (Open Collector Output Module)
The MOD-16 does not occupy a network
address. The MOD-16 is at a subaddress
of the MOI-7 to which it is connected. The
subaddresses of any given MOD-16s are
determined by their position in the string of
MOD-16s.
The output cable from the MOI-7 connects
to the first MOD-16, which has the
subaddress of 001-016 as shown above.
Each additional MOD-16 in the chain has
the next block of 16 addresses.
You may connect a maximum of 8
MOD-16s and MID-16s to an individual
MOI-7 for a total of 128 open collector
outputs and 128 general purpose inputs.
Using The MKB-4
Keyboard/Annunciator
Panel in Local Mode
See Figure 32, page 3-4, for the location of
the display keys and LEDs.
When the MKB-4 Keyboard/ Annunciator
Panel is installed, only the display, LEDs,
and display control keys are visible. The
ACKnowledge keys and other controls are
hidden behind a locked door. Unlock and
open the door to gain access to those keys
and controls.
The Display
The display has two lines of 40 characters
each. What is shown on the display de-
pends on the state of the System. The
display contains a back light which turns on
automatically when any key is pressed or
an event is reported. The back light turns
off automatically after 5 minutes of system
inactivity.
The System has several displays. When
the System is Normal, the display shows:
[time/date] SYSTEM
[system message] NORMAL
When an event has been annunciated, the
System alternates between the following
three displays:
[address] [custom message] [ACK STATUS or BLANK]
[event number] [device type ] [trouble type] [IN or 0UT]
[address] [type of device in trouble] or [BLANK] [ACK
STATUS or BLANK] [event number] [time/date] [IN or 0UT]
