“Feed-Back” information, from the Field Satellite units back to the Computer. In so doing, it also
displays a certain amount of information for viewing by the operator.
The MAXI Interface Module is capable of communicating with FOUR (4) different wire
paths at one time. Each wire path is capable of communicating to a maximum of TWENTY
EIGHT (28) Field Satellites or Decoder Devices.
The MAXI Interface Expansion Module provides for the capability of FOUR (4) additional
wire paths for a Total of EIGHT (8) wire paths on the system. Each wire path on the Expansion
Module is also capable of communicating to a maximum of TWENTY EIGHT (28) Field Satellites
or Decoder Devices.
All information for any Group Activity, Channel Activity and Station Activity is displayed on
the MAXI Interface Module - even when both the MIM Interface Unit and the MIM-X Expansion
Unit are used.
A MEMORY Switch provides for the preserving of status information or operational
information for viewing at some future time.
Full MANUAL Operation of any Satellite, on the system, may be performed from the

OPERATIONS
MAXI® INTERFACE MODULE (MODEL MIM)
MODULE FUNCTION:
The MAXI Interface Module function is to take the signal from the computer Serial Output
Port and transform it to a signal to be transmitted to the Field Stand-by Modules. Through this
communication transmission, over the various 2-Wire Paths, the Field Stand-by Modules (or
Satellite units) are instructed “WHEN” to operate and what “STATION” to operate.
In addition the MAXI Interface Module also receives, via the 2-Wire Path, “Feed-Back”
information from the Field Satellite Units. This “Feed-Back” information is passed on to the
Computer. In addition the MAXI Interface Module also displays some of this information,
directly to the user via various LED’s located on its front panel.
A third function of the MAXI Interface Module Is to provide a means of MANUAL Operation, of
the Field Stand-by Modules, directly from it. In so doing “Feed-Back” information will also be
received and displayed by the Interface Module Unit.
The MAXI Interface Module is also capable of displaying and conveying a certain amount of
”self-testing” and “trouble shooting” status data to the user.
FRONT PANEL FAMILIARIZATION:
Let us first take a look at the Front Panel to familiarize the user with its components and
benefits.
FIGURE #12: FRONT PANEL ASSEMBLY
12
GROUP ACTIVITIES LIGHTS:
PURPOSE...
To provide indication of activity or satellite operation on the 2-Wire Path.
OPERATION...
There are eight (8) GROUP ACTIVITY (or 2-Wire Path) lights located in the upper left hand
corner of the front panel, (Refer to FIGURE #13 - Group or Wire Path Activity Lights).
FIGURE #13: GROUP OR 2-WIRE PATH ACTIVITY LIGHTS
You will note that there is a light for each of the eight (8) 2-Wire Paths possible on a system.
When any of the up to 28 devices in a group are addressed and respond with a feedback
condition of “ON”, the corresponding GROUP ACTIVITY light will turn “ON”.
SATELLITE FAILURE TO RESPOND...
Should a satellite unit or a number of satellite units, fall to respond when they are being
addressed, the activity light for that 2-Wire Path will continue to “BLINK” for as long as they
fail to respond. Even if all other satellites have returned to their “REST” position, this indicating
light will continue to “BLINK”. Thus you have a visual indication that a satellite or a number of
satellites have tailed to operate and you have some type problem.
13
MEMORY SWITCH:
PURPOSE...
To provide a visual indication of “PAST” Activity on the various 2-Wire Paths.
OPERATION...
To the immediate RIGHT of the GROUP ACTIVITY LIGHTS is a two-position Rocker Type
MEMORY Switch, having an “ON” and an “OFF” position. (Refer to FIGURE #14 - Memory Switch).
FIGURE 14: MEMORY SWITCH
With the MEMORY Switch in the “OFF” POSITION the GROUP Activity LIGHTS will function as
described under “GROUP ACTIVITY LIGHTS” - immediately proceeding this section.
With the MEMORY Switch in the “ON” position - once activity has taken place on any of the
2-Wire Paths - the GROUP ACTIVITY LIGHT will REMAIN lighted. This will occur even though all
satellites have finished operation and have returned to their “REST” position. Thus you have a
visual indication that activity has taken place some time prior to the present time. To “RESET”
the activity lights - place the MEMORY Switch in the “OFF” position and then switch back to
“ON”, if desired. The LIGHTS will now be reset.
CAUTION ! Before doing so, however, be sure you have checked all other
status information, that you desire to observe, as this
information will also be “RESET”.
14
CHANNEL/STATION SWITCH:
PURPOSE...
To provide selection of either the CHANNEL ACTIVITY LIGHTS or the STATION ACTIVITY LIGHTS.
OPERATION...
Just below the Group Activity Lights is a two-position Rocker Type CHANNEL/STATION Switch.
(Refer to FIGURE #15 - Channel/Station Switch).
FIGURE #15: CHANNEL/STATION SWITCH
This Switch, when in the “UP” position, selects the display lights to indicate CHANNEL ACTIVITY.
When the Switch is in the “DOWN” position it selects the display lights to indicate the STATION
ACTIVITY.
15
CHANNEL ACTIVITY LIGHTS:
PURPOSE...
To provide an indication of CHANNEL Activity or satellite operation, on a given 2-Wire Path.
OPERATION...
Just to the RIGHT, of the TOP, of the CHANNEL/STATION Switch and just after the Channel
Activity designation is an indicating light. When the Channel/Station Switch is in the “UP”
position - this indicating light will be lighted - indicating that the activity lights are now set to
display CHANNEL Activity or SATELLITE Activity on a given 2-Wire Path.
Just to the RIGHT, of the CENTER, of the Channel/Station Switch are twenty eight (28)
CHANNEL Activity LIGHTS - one for each of the twenty eight (28) individual channels available
on a given 2-Wire Path. (Refer to FIGURE #16 -Channel Activity Lights).
FIGURE #16: CHANNEL ACTIVITY LIGHTS
With the MEMORY Switch in the “OFF” position, EACH of these CHANNEL ACTIVITY LIGHTS will
indicate when a given channel or satellite, on a particular wire path, is in operation.
16
Operation may be initiated in any of the following ways:
a) By a program from the computer.
b) Manually from the Interface Module.
c) Manually from the Satellite in the Field.
SATELLITE FAILURE TO RESPOND...
With the MEMORY Switch in the “OFF” position - any satellite falling to respond, when it has
been addressed, will be indicated by its CHANNEL ACTIVITY LIGHT > “BLINKING”.
With the MEMORY Switch in the “ON” position - once a satellite has responded, even though it
may now be at its “REST” position, the CHANNEL ACTIVITY LIGHT for it will REMAIN LIGHTED.
Thus you have a visual indication that activity, by that satellite has taken place some time prior
to the present time. To “RESET” the CHANNEL ACTIVITY LIGHTS place the MEMORY Switch to
the “OFF” position and then back to “ON”, if desired.
CAUTION ! Before so doing, however, be sure you have checked all other
status information, that you desire to observe, as this
information will also be “RESET”.
STATION ACTIVITY LIGHTS:
PURPOSE...
To provide an indication of STATION ACTIVITY on a given satellite that is in operation at the
time.
OPERATION...
Just to the RIGHT, of the BOTTOM, of the Channel/Station Switch and just after the Station
Activity designation is an indicating light When the Channel/Station Switch is in the “DOWN”
position - this indicating light will be lighted - indicating that the Activity lights are now set to
display SATELLITE STATION Activity for any satellite in operation at the present time.
Just to the RIGHT, of the CENTER, of the Channel/Station Switch are twenty four (24) STATION
ACTIVITY LIGHTS - one for each of the 12 or 24 stations available on a field satellite. (These
are the SAME indicating lights that are used to indicate Channel Activity, as described in the
preceding section). Refer to FIGURE #17 - Station Activity Lights.
17
FIGURE #17: STATION ACTIVITY LIGHTS
With the MEMORY Switch in the “OFF” position STATION ACTIVITY LIGHTS will indicate which
station, of a given satellite is in operation, when the satellite has been started either by a
program in the Computer or started Manually from the Interface Module.
NOTE ! If the satellite has been started or is being operated manually
at the satellite in the field, there will be NO STATION
INDICATION.
STATION FAILURE TO RESPOND...
With the MEMORY Switch in the “OFF” position - any station of a given satellite, tailing to
respond, when it is being addressed, will be indicated by the STATION ACTIVITY LIGHT for that
station “BLINKING”.
With the MEMORY Switch in the “ON” position - once the satellite has “stopped” on a station,
even though it may now be on some other station or at the “REST” position, the STATION
ACTIVITY LIGHT, for that station will REMAIN LIGHTED. Thus you have visual indication of each
station that has operated. To “RESET” the STATION ACTIVITY LIGHTS place the MEMORY Switch
In the “OFF” position and then back to “ON”, if desired.
CAUTION ! Before so doing, however, be sure you have checked all other
status information, that you desire to observe, as this
information will also be “RESET”.
18
OUTPUT CIRCUIT BREAKERS:
PURPOSE...
To prevent damage to the Interface Module from shorts on the 2-Wire Path.
OPERATION...
Just to the RIGHT of the CHANNEL/STATION ACTIVITY LIGHTS are four (4) Rocker Switch type
OUTPUT CIRCUIT BREAKERS - one for each of the possible four (4) 2-Wire Paths on the MAXI®
Interface Module. (Refer to FIGURE #18 -Output Circuit Breakers).
FIGURE #18: OUTPUT CIRCUIT BREAKERS
With the OUTPUT CIRCUIT BREAKER Switch in the “ON” position, the 2-Wire Path is connected
electrically to the Interface Module and communication to the field, over this 2-Wire Path can
take place. With the OUTPUT CIRCUIT BREAKER Switch in the “OFF” position, the 2-Wire Path is
electrically DISCONNECTED from the Interface Module and NO communication can take place
over this 2-Wire Path.

“AUTOMATIC” operation of the satellites from the Computer.
19
OPERATION...
Just below the CHANNEL/STATION Switch is the two (2) position rocker type MODE of
OPERATION Switch. (Refer to FIGURE #19 - Mode Switch).
FIGURE #19: MODE SWITCH
With this switch in the “UP” or “MANUAL” POSITION the light to the RIGHT of the word MANUAL
will be lighted - indicating that the INTERFACE MODULE is now to be operated MANUALLY
and NOT from the Computer. With the switch in this position, Field Satellite units can ONLY
be operated MANUALLY from the interface Module or from the Field Satellite unit itself. Field
Satellites CAN NOT be Automatically operated from the Computer. The MANUAL indicating
LIGHT will ALWAYS be lighted to give you visual indication that the system Is in the MANUAL
MODE of operation.
With the MODE of OPERATION Switch in the “DOWN” or “AUTOMATIC” position - Field Satellite
units may be operated Automatically from programs in the computer or manually operated
from the field satellite unit itself. The indicating Light, to the RIGHT of the word MANUAL will
be “OFF”, when the MODE of OPERATION Switch is in the “AUTOMATIC” position.
With the MODE Switch in either the MANUAL or AUTOMATIC position, the GROUP ACTIVITY
LIGHTS, the CHANNEL ACTIVITY LIGHTS and/or the STATION ACTIVITY LIGHTS will function as
previously described.
20
GROUP WINDOW & UP/DOWN BUTTONS:
PURPOSE...
