Getting Started
Getting Started
This chapter contains information on the TMS MC2 Logic Board Adapter
Hardware Support package, and information on connecting your logic analyzer to
your system under test.
Support Package Description
The TMS MC2 Logic Board Adapter is nonintrusive hardware that allows the
logic analyzer to acquire data from a microprocessor in its own operating
environment with little affect on that system.
The TMS MC2 Logic Board Adapter can be used with a variety of interposer
boards. An example of an interposer board is the MPROBE interposer board
from Ironwood electronics. Signals from the microprocessor flow through the
MPROBE interposer board, and then, to the TMS MC2 Logic Board Adapter
into the P6434 probes and through the probe cables to the logic analyzer.
Contact your Tektronix representative if you are interested in other interposer
board solutions.
Support Software Compatibility
The TMS MC2 Logic Board Adapter requires a Tektronix software support
package. At the time of printing, the compatible software support package is the
TMS113. When using the TMS MC2 Logic Board Adapter with the TMS113
software, choose any one of the PG370 clocking options to acquire data.
Contact your Tektronix representative to determine which latest software support
package is compatible with the TMS MC2 Logic Board Adapter Hardware
Support package.
Logic Analyzer Configuration
To use the TMS MC2 Logic Board Adapter Hardware Support package you need
a Tektronix logic analyzer equipped with two 102-channel modules. The modules
must be in adjacent slots and merged.
References to a 204-channel module include two merged 102-channel modules.

Assembling the Probe Adapter
The TMS MC2 probe adapter assembly consists of one board, the Logic board.
CAUTION. To prevent static damage, handle components only in a static-free
environment. Static discharge can damage the microprocessor, the probe adapter,
the probes, and the module.
Always wear a grounding wrist strap, heel strap, or similar device while
handling the microprocessor and probe adapter.
To assemble the probe adapter, follow these steps:
1. To discharge any static electricity, touch the ground connector located on the
logic analyzer. Then, before you remove the probe adapter circuit boards
from their protective bags, touch each bag to discharge stored static
electricity.
2. Align the Logic board connector pins with the connector pins on the
connecting circuit board, and press firmly to seat the board connector (see
Figure 1–1). Both connectors are polarized and will only mate in one
orientation.
190-pin mictor
NOTE. To ensure a reliable electrical connection between the Logic board and the
connecting circuit board, the 190-pin mictor connector must be completely seated
at both ends (see Figure 1–1).
