2.5 Setup for ULINK2/ME and LPC185X-Xplorer++ Board
Option A: With ULINK-ME debugger
To run the KEIL examples you will need the following and the image shows the each components:
•ULINK-ME
•10-pin ribbon cable
•LPC185X-Xplorer++ Board
•Two USB AM to Micro B cable
Fig.14
Steps to setup the ULINK-ME and LPC185X-Xplorer++ Board:
(Note: Please refer keil knowledgebase article for connecting ULINK2/ME 10-pin ribbon cable to NGX
Xplorer++)
Step 1: Connect one end of 10-pin ribbon cable to ‘ULINK-ME 10-pin box header’ as show in the
following image.

USER MANUAL: LPC185x –Xplorer++

Fig.15
Step 2: Connect other end of 10-pin ribbon cable to ‘10-pin box header’ of the LPC185X-Xplorer++ board
as shown in the following image.
Fig.16
Step 4: Connect one end of ‘USB AM to Micro B’ cable to LPC185X-Xplorer++ board and other end to
computer and connect one end of ‘USB AM to Micro B’ to ULINK-ME and other end to computer as
shown in the following image.

Fig.17
The setup is now ready to be used for development with KEIL IDE and ULINK-ME.
Option B: With ULINK2 debugger
The LPC185X-Xplorer++ board has on board ‘10-pin SWD/JTAG box header’; ensure that the
ULINK2/ME must have ‘10-pin SWD/JTAG’ support for development. The ULINK2 debugger, ‘20-pin
to 10-pin adapter’ and 10-pin ribbon cable are not a part of the LPC185X-Xplorer++ package, the user
needs to buy separately.
To run the KEIL examples you will need the following and the image shows the each components:
•ULINK2
•ARM JTAG to Cortex JTAG Adapter (20-pin to 10-pin Adaptor)
•10-pin ribbon cable
•LPC185X-Xplorer++ Board
