ZUD-CD-10-0092 19/19

CHAPTER 4 LONG TERM TRACE OPTION

This chapter explains an optional product QB-V850E2-SP for extending the trace memory.

4.1 General

The QB-V850E2-SP is a trace memory extension for IECUBE2. Please make sure the supported version of

debugger software.

Figure 4-1. QB-V850E2-SP

4.2 SETUP

PROCEDURE

This section describes how to connect the QB-V850E2-SP to the IECUBE2 main.

1. Remove the cover from the connector on

the top side of the QB-V850E2-SP module.
It might be necessary to loose the screw a
little bit.

2. Make sure that the IECUBE2 is switched off

and the USB cable and power supply
adapter is not connected to the IECUBE2
main module. Then Remove the cover on
the bottom side of the IECUBE2 main
module.

3. Mount the IECUBE2 main module on the

QB-V850E2-SP as shown in the picture.
Now connect the USB cable and power
supply adapter to the IECUBE2 and turn
the IECUBE2 on.

IECUBE2 detects trace memory extension automatically when QB-V850E2-SP is connected. Configuration in

hardware or debugger software is not necessary.
