To connect an E2 emulator to the connector on the user system, use the connector conversion adapter that
comes with the E2 and the user system interface cable. Figure 2-2 shows an example of the connection.
After connecting the user system interface cable to the connector conversion adapter, connect the connector
conversion adapter to the connector on the user system.
The connector conversion adapter is provided with a switch. Setting for the switch must be on the “1” side for
the RH850. Operation is not guaranteed if the switch is on the “3” side. For setting the switch, refer to Table

Description
1
The target device is an RH850 microcontroller (default setting).
3
The target device is an RL78 microcontroller.
CAUTION
Note on connector insertion and removal (1):
When connecting or disconnecting the user-system interface cable and the connector conversion
adapter, grasp both sides of the board of the connector conversion adapter. Pulling the user-system
interface cable itself will damage the wiring.
CAUTION
Note on connector insertion and removal (2):
Be aware that the connector conversion adapter must be inserted with the correct orientation.
Connecting the connector conversion adapter with the wrong orientation may cause damage.
