Connection to Your Target System

You need appropriate pins on the target system for connecting the
target system board to the header connection on the cable. These
connectors must be standard 0.025−inch square male pins that have
dedicated traces to the target system control pins. You can connect to
these pins with a header connector or a flying lead connector.
Note: The XChecker cable draws its power from the target system
through V
the target system, must be stable. Do not connect any signals before
connecting V

Header Connector

When you layout the printed circuit board for use with JTAG in-
system programming and testing, a few adjustments will make the
process of connecting and downloading easier.
•
The header connector is two standard 9-pin (8 signals, 1 key) header
connectors that fit 0.025" square male pins. The pin order is listed in
Table 2-2. These header connectors are keyed to assure proper
orientation to the cable assembly.

Flying Lead Connectors

The flying lead connector is two flying lead header connectors with
eight standard individual female connectors on one end that fit onto
0.025" square male pins. Each lead is labeled to identify the proper
pin connection.

Cable Connections

Connections between the cable assembly and the target system use 6
leads. For connection to JTAG boundary-scan systems you need only
ensure that the VCC, GND, TDI, TCK, TMS and RD (TDO) pins are
connected.
Once installed properly, the connectors provide power to the cable,
allow download and readback of configuration data, and provide for
logic probe of device pins.
