BUILDING A SYSTEM
Family Compatibility
Mechanically, the plug-in modules are very similar to
other TEKTRONIX product families. However, they are
not electrically compatible. Therefore, the TM 503 inter-
face has barriers on the mating connectors between pins 6
and 7 to insure that incompatible plug-ins cannot be
inserted. See Figure 1. A compatible module will have a
matching slot between pins 6 and 7 of its main circuit
board edge connector. This slot and barrier combination is
the primary keying assignment.
Another
modules
identifier for TM 500-compatible plug-in
is the white color of the release latch.
Customizing the Interface
The modularity of this instrumentation system provides
for a host of functions to be performed by the plug-in
modules. Specific functions are grouped into families or
classes, of which there may be several plug-in module

members, For instance, some classes are Power Supplies,
Signal Sources, Measurement and so forth. Each modular
member of a functional family will have a second slot
peculiar to its family assignment located in its edge
connector. The TM 503 user can “program” one or more
compartments to accept only members of that family by
installing a second barrier in the interface connector to
match the module's stot location. Entire TM 503’s could be
“programmed” in this manner to set up instrumentation
systems for specific work functions. For extra barriers
order TEKTRONIX Part Number 214-1593-02.
a
Jumper wires can be used to further specialize the
interface. Compartments can be made to ‘talk’ to each
other by connecting jumpers on the back side of the
interface board, using pins 14 through 28, A-side and B-side
both, of the interconnecting jacks. See the following
description of catalog Option 2. Refer to each plug-in
module’s Manual for the 1/O assignments of each pin at the
rear interface. Once having made interconnections of a
specialized nature, it is recommended that barriers be
installed on the interconnecting jacks to insure module
compatibility with the customized wiring.
